FreeDOS commands you need to know

Just install your legacy software under FreeDOS, and you’ll be good to go! 4 / 4. Many embedded systems run on DOS, although modern systems may instead run on Linux. If you support an older embedded system, you might be running DOS. And FreeDOS can fit in very well. If you get a scrolling list of “Invalid Opcode” errors when you boot the FreeDOS installation CD-ROM on VirtualBox, this is a bug in VirtualBox since we released FreeDOS To fix: When you boot the FreeDOS install CD-ROM, at the first “Welcome to FreeDOS ” boot screen, press the Tab key to edit the boot options.

Lots of people download binary distributions of curl and libcurl. This document does not describe how to install curl or libcurl using such a binary package. This document describes how to compile, build and install curl and libcurl from source code.

You can download and install curl and libcurl using the vcpkg dependency manager:. The curl port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository.

If you get your code off a git repository instead of a release tarball, see the GIT-INFO file in the root directory for specific instructions on how to proceed. A normal Unix installation is made in three or four steps after you've unpacked the source archive :.

If you have write permission in that directory, you can do 'make install' without being root. An example of this would be to make a local install in your own home directory:. The configure script always tries to find a working SSL library unless explicitly told not to. If you insist on forcing a build without SSL support, even though you may have OpenSSL installed in your system, you can run configure like this:. Something like this should work:. If you have shared SSL libs installed in a directory where your run-time linker doesn't find them which usually causes configure failuresyou can provide this option to gcc to set a hard-coded path to the run-time linker:.

To force a static library compile, disable the shared library creation by running configure like:. If you're a curl developer and use gcc, you might want to enable more debug options with the --enable-debug option. But if you want to alter it, you can select how to deal with each individual library.

Especially important is how to install free dos understanding if you are not going to follow the advice given above. If your app is misbehaving in some strange way, or it is suffering from memory corruption, before asking for further help, please try first to rebuild every single library your app uses as well as your app using the debug multithreaded dynamic C runtime. There are other make targets available to build libcurl with more features, use:. If you have any problems linking libraries or finding header files, be sure to verify that the provided Makefile.

It is also possible to override these paths with environment variables, for example:. If you want to use these you need to set these vars:. Almost identical to the unix installation. Run the configure script in the curl source tree root with sh configure. The configure utility, unfortunately, is not available for the Windows environment, therefore, you cannot use the various disable-protocol options of the configure utility on this platform. You can use specific defines to disable specific protocols and features.

To set this definition you have the following alternatives:. Compilation has been verified with lwIP 1. Otherwise the linker will look for dynamic import symbols.

It is not necessary to use the option --without-openssl. When Secure Transport is in use, the curl options --cacert and --capath and their libcurl equivalents, will be ignored, because Secure Transport uses the certificates stored in the Keychain to evaluate whether or not to trust the server. This, of course, includes the root certificates that ship with the OS.

The --cert and --engine options, and their libcurl equivalents, are currently unimplemented in curl with Secure Transport. When building curl for Android it's recommended to use a Linux environment since using curl's configure script is the what tricks can i do to raise my body temperature way to build curl for Android. Once you have installed the Android NDK, you need to figure out where it has been installed how to use wallflowers - bath and body works then set up some environment variables before launching configure.

When building on Linux or targeting other API levels or architectures, you need to adjust those variables accordingly. After that you can build curl like this:. Set environment variables to point to the cross-compile toolchain and call configure with any options you need. Be sure and specify the --host and --build parameters at configuration time. The --prefix parameter specifies where curl will be installed.

If configure completes successfully, do make and make install as usual. There are a number of configure options that can be used to reduce the size of libcurl for embedded applications where binary size is an important factor. First, be sure to set the CFLAGS variable when configuring with any relevant compiler optimization flags to reduce the size of the binary. Note that newer compilers often produce smaller code than older versions due to improved optimization.

Be sure to specify as many --disable- and --without- flags on the configure command-line as you can to disable all the libcurl features that you know your application is not going to need. The GNU compiler and linker have a number of options that can reduce the size of the libcurl dynamic libraries how to install free dos some platforms even further.

Be sure also to strip debugging symbols from your binaries after compiling using 'strip' or the appropriate variant if cross-compiling. If space is really tight, you may be able to remove some unneeded sections of the shared library using the -R option to objcopy e. You may find that statically linking libcurl to your application will result in a lower total size than dynamically linking. Note that the curl test harness can what are anodes used for the use of some, but not all, of the --disable statements suggested above.

Use will cause tests relying on those features to fail. The test harness can be manually forced to skip the relevant tests by specifying certain key words on the runtests. Following is a list of appropriate key words:. This is a probably incomplete list of known CPU architectures and operating systems that curl has been compiled for. If you know a system curl compiles and runs on, that isn't listed, please let us know! Related: Changelog Developing curl Get help.

Jump to navigation. In my previous article, 8 Linux file managers to try , I compared a number of file managers, but there was not enough space to go into detail about any of the several file managers that I mentioned briefly.

This article will delve a bit further into Midnight Commander, and I plan to write more to cover some of the other file managers in more detail.

Our latest Linux articles. It is particularly useful when a GUI is not available but can also be used as a primary file manager in a terminal session even when you are using a GUI.

It can be used with almost any of the common shells and remote terminals through SSH. Clicking on a file will select it, clicking on a menu item or a function key button will launch that menu or function.

This command installs Midnight Commander:. The figure below shows Midnight Commander when run as root in a terminal emulator session. The user interface for Midnight Commander is two text-mode file panels, left and right, which each display the contents of a directory.

The top of each panel displays the name of the current directory for that panel. The bottom portion of the interface displays information about the file or directory highlighted in each panel, a hint feature, and a line of function key labels; you can simply press the function key on your keyboard that corresponds to the function you want to perform or you can use the mouse to click on the desired button.

The selected file or directory is highlighted by a bar, white on blue in the figure above. Multiple selections can be made by holding the Shift key and pressing the Up or Down arrow keys. Just below each directory panel is an area that displays a small bit of information about the selected file. That includes the name, size, and permissions. This data is not displayed by default. To enable the display of file information, select either the Right or Left menu item , then choose Listing mode , select the User mini status line and press the Enter key to place an X there.

Then select OK and press the Enter key. Between the hint line and the function keys is a command line where you can type in any Linux command. Just above the hint line is a bit of information about the total space and the amount of free space in the current file system. This information is not about the current directory, it is for the filesystem as a whole.

Along the very top of the Midnight Commander interface is a menu bar containing menu items for configuring Midnight Commander, the left and right panes, and for issuing various file commands. Midnight Commander, right pane menu open. You can use the mouse and click on the menu items, or press the F9 key to open the pull-down menus. Once the menu is opened, you can select a different one on the menu bar by using the Right and Left arrow keys. The Up or Down arrow keys are used to select one of the items in the current menu.

Simply press the Enter key to activate the selected menu item. Configuration of the panels is accomplished by selecting the Left or Right menu item from the menu bar. You can select the content of the panel, such as detailed information about the file selected in the other panel or a tree view. Navigation of the filesystem in the directory panes is accomplished with the arrow and tab keys. The Up or Down arrow keys allow selecting a file or directory.

Press the Enter key to enter a highlighted directory. Select the double dot.. Use the Tab key to switch between the two directory panes. Navigation and menu selections can also be made with the mouse if you are running Midnight Commander in a terminal session on a GUI desktop. Just single click on any menu item, file, or directory to select it.

One you have located and highlighted a file on which you want to perform some action, the function keys provide shortcuts to basic file operations such as copy, move, delete and so on. To delete a file, for example, locate the desired files, highlight them, and press the F8 key to delete the file or files. You can also delete directories and entire directory trees and all of their contents recursively. Midnight Commander will also ask you to verify that you wish to do that.

Use the F5 key to copy highlighted files from one panel to the other, and the F6 key to move the highlighted file to the directory in the other panel.

Midnight Commander allows viewing of text files. Highlight the desired file and press the F3 key. The up and down arrow keys allow scrolling of long files.

The F3 key , or pressing Esc key twice will return Midnight Commander to the directory panel. You can also edit files by pressing F4 key instead of F5 key. I prefer vim for editing but the Midnight Commander editor is fine for making a few minor changes. One of my favorite features of Midnight Commander—and of my other favorite file managers—is the ability to drill down into the contents of various types of archive files like zip, rpm, tar, tgz, cpio and others. Simply highlight the desired archive file and press the Enter key.

Midnight Commander shows the complete contents of the archive. You can navigate through the directory hierarchy inside the archive and open text files and scripts to view their content. Midnight Commander makes it possible to directly copy individual files from the archive out to replace damaged or missing ones. I have used this capability many times to recover a damaged file from a backup tarball or to copy a good copy of a damaged executable or configuration file out of an rpm.

Running scripts of various types, like BASH scripts is very simple. Just highlight the executable file and press the Enter key. MC executes the script and displays the result. Press the Enter key to return to Midnight Commander. Between the hint line and the function key line is a command line. To enter a command just start typing. When you press the Enter key the command will be executed and the results displayed. To return to Midnight Commander, press the Enter key. Midnight Commander does not provide the more advanced command line editing that BASH does, but it does provide a History menu with a short listing of recent commands.

Use the arrow keys to select the desired command and press the Enter key to execute it. Midnight Commander has an excellent help function. Just press the F1 key to open the help panel. Navigate to the highlighted Contents and press the Enter key to access the body of the Help function. Navigation through the Help is by keyboard or mouse. Additional documentation is available on the Midnight Commander web site. It contains some good information but it is not nearly as complete as the Help feature.

In fact, I was very surprised by the quality of the Midnight Commander Help feature. In my experience, Help features are quite terse and provide little or no big picture guidance. Some tend to be marginally helpful at best. The MC Help feature is really more like a complete set of documentation than what I have come to think of as typical help. Be certain you are in the correct pane and have highlighted the correct file before pressing F8 to delete a file or entering a command that might alter, delete or move a file to an obscure location.

Midnight Commander is a very powerful, easy to use text mode file manager. It rivals most of the GUI file managers in features and ease of use. I find myself using it many times instead of a one of the GUI file managers. I recommend that you try it for yourself and see how it works for you. Then you navigate just by pressing Left or Right, without the need to use Enter or navigate until the top to select the double dot.

MC UI is too heavy for me, i don't understand why they need to add a menubar and split the path list, i like much more Ranger. I install MC on every Linux system I use. It is much better than a bare terminal if you cannot get into X and need to fix your system. MC is awesome because it's a clone of Norton Commander which was awesome.
