env is a shell command for Unix and Unix-like operating systems. It is used to either print a list of environment variables or run another utility in an altered environment without having to modify the currently existing environment. Using env, variables may be added or removed, and existing variables may be changed by assigning new values to them.
The SET command without any arguments displays all environment variables along with their values; SET " ", zero or more spaces, will include internal variables too. In CMD.EXE , it is possible to assign local variables that will not be global using the SETLOCAL command and ENDLOCAL to restore the environment.
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
PATH is an environment variable on Unix-like operating systems, DOS, OS/2, and Microsoft Windows, specifying a set of directories where executable programs are located. In general, each executing process or user session has its own PATH setting.
The license was GPL-1.0-or-later. "In addition to supporting backward-compatibility for scripting, Bash has incorporated features from the Korn and C shells.

TMPDIR is the canonical environment variable in Unix and POSIX [1] that should be used to specify a temporary directory for scratch space.Most Unix programs will honor this setting and use its value to denote the scratch area for temporary files instead of the common default of /tmp [2] [3] or /var/tmp.
The C shell implements both shell and environment variables. [14] Environment variables, created using the setenv statement, are always simple strings, passed to any child processes, which retrieve these variables via the envp[] argument to main(). Shell variables, created using the set or @ statements, are internal to C shell. They are not ...
Variable completion is the completion of the name of a variable name (environment variable or shell variable). Bash, zsh, and fish have completion for all variable names. PowerShell has completions for environment variable names, shell variable names and — from within user-defined functions — parameter names.
