In most DOS and UNIX command shells, as well as in the Microsoft Windows command line interpreters cmd.exe and Windows PowerShell, the working directory can be changed by using the CD or CHDIR commands. In Unix shells, the pwd command outputs a full pathname of the working directory; the equivalent command in DOS and Windows is CD or CHDIR ...
Alternatively, from command shells such as bash, a user can change environment variables for a particular command invocation by indirectly invoking it via env or using the ENVIRONMENT_VARIABLE=VALUE <command> notation. A running program can access the values of environment variables for configuration purposes.
Git does periodic repacking automatically, but manual repacking is also possible with the git gc command. [46] For data integrity, both the packfile and its index have an SHA-1 checksum [47] inside, and the file name of the packfile also contains an SHA-1 checksum. To check the integrity of a repository, run the git fsck command. [48] [49]
The following is an example build command that uses this file to specify options to gcc. The output of command pkg-config --libs --cflags libpng is passed to gcc via its command line interface. $ gcc -o test test.c $( pkg-config --libs --cflags libpng )
In computing, Bash (short for "Bourne Again SHell,") [6] is an interactive command interpreter and command programming language developed for UNIX-like operating systems. [7] Created in 1989 [ 8 ] by Brian Fox for the GNU Project , it is supported by the Free Software Foundation and designed as a 100% free alternative for the Bourne shell ( sh ...
A restricted mode is part of the POSIX specification for shells, and most of the Linux/Unix shells support such a mode where several of the built-in commands are disabled and only external commands from a certain directory can be invoked. [72] [73] PowerShell supports restricted modes through session configuration files or session ...
An INI file is a configuration file for computer software that consists of plain text with a structure and syntax comprising key–value pairs organized in sections. [1] The name of these configuration files comes from the filename extension INI, short for initialization, used in the MS-DOS operating system which popularized this method of software configuration.
Environment Modules modulefiles are written in the Tcl (Tool Command Language) and are interpreted by the modulecmd program via the module [7] user interface. The key advantage of Environment Modules is that it is shell independent and supports all major shells such as Bash (bash), KornShell (ksh), Z shell (zsh), Bourne shell (sh), tcsh, and C ...
