Mod edit #2: Just a note to say that this has an install feature to modify your registry, to auto-load this script in the future. It can be uninstalled in a similar way to undo this feature. By default, it doesn't install itself permanently.
============
ALIASES
First of all it declares the following builtin aliases (doskey macros)
alias
show all aliases
alias name=text
assign name for the commands
alias -r [FILENAME]
read a file FILENAME or %CMD_ALIASFILE% and load new list of aliases
unalias name
remove alias by name
history
show the history of the current session
history -c
clear the current history of commands
history -w
write (append) the current history ot the file defined in %CMD_HISTFILE%
cd [path]
show the current directory or proceed to the directory path
cd -
return to the previously visited directory
cd ~
proceed to the %USERPROFILE% directory
exit, CTRL-D
write the history to the file history file and finish the current cmd.exe session. Pressing CTRL-D buttions should be ended by pressing the ENTER button.
============
ENVIRONMENT
CMD_SETCMDDIR
Points to the directory where the main script setcmd.bat is located
CMD_ALIASFILE
Define the name of the file of aliases or DOSKEY macros.
CMD_ALIAS_NOBUILTINS
Any non-empty value disables setting of builtin aliases at startup.
CMD_HISTFILE
Define the name of the file in which command history is saved.
CMD_HISTFILESIZE
Define the maximum number of lines in the history file.
CMD_HISTSIZE
Define the maximum number of commands remembered by the buffer. By default DOSKEY stores 50 latest commands in its buffer.
User file
Putting setcmd.rc.bat file to CMD_SETCMDDIR, HOME or USERPROFILE directory you can change behavior of the main script. You can define some variables (for example set PATH etc) or re-declare the variables from the list above.
============
AUTORUN
Run the script once for automate its execution when cmd.exe launching:
Code: Select all
setcmd autorun -i
Run the following command to uninstall the script
Code: Select all
setcmd autorun -u
In this case (only this case!) the script modifies the Window Registry node "HKCU\Software\Microsoft\Command Processor" to autoload the script. This has been developed to give to the end user the choice how to use the script.

Example of aliases file is here: https://github.com/ildar-shaimordanov/c ... md.aliases

::
:: The tool was developed to enhance the functionality of `cmd.exe`
:: similar to Unix-like shells. It is completely written as batch script
:: and does npt add any external binaries. Nevertheless, it gives more
:: functions and flexibility to `cmd.exe` and do maintainance little bit
:: easier.
::
:: In fact, this script is weak attempt to be closer to other shells -
:: powerful, flexible and full-functional ones. Nevertheless, it works!
:: This script can be found useful for those folks, who are not permitted
:: to setup any other binaries excepting those applications permitted for
:: installation. The better way is to use the other solutions like
:: `Clink`, `ConEmu` or something else.

:: # USER DEFINED FILE
::
::
:: The user defined file `setcmd.rc.bat` allows to customize the user's
:: environment. Firstly, it is checked for existance in the same directory
:: where `setcmd.bat` is located, further it is checked under the `HOME`
:: directory and finally under the user's profile. If these files exist
:: they are called and affects on the further execution. Each of them can
:: override previous settings.
::
:: This behavior is very close to the existing in unix world when settings
:: of `~/.bashrc` override settings of `/etc/bashrc`.
::
:: The `CMD_SETCMDDIR` environment variable points to the directory where
:: the main script `setcmd.bat` is located. It can be used, if some
:: settings are placed under this directory.

::
::
:: Behaviour of the script depends on some environment variables described
:: below. Most of them have synonyms in unix and the same meaning.
::
:: Uncomment a line if you want to turn on a feature supported by a
:: variable. The better place for tuning all these variables is auxiliary
:: `setcmd.rc.bat` script (see the description above).
