Files related to environment variables may also have / etc/bashrc, etc., but this is the shell variable, which is local and works for specific shellers. / etc/profile is global and applies to all shell.

The profile file tells shell what language to use, what shell to use, the search path for the command, and so on.

Some standard environment variables:

SHELL default shell

LANG default language

PATH linux looks for the default path of a command, which generally includes / bin,/usr/bin,/sbin,/usr/sbin

/ usr/X11R6/bin,/opt/bin,/usr/local/bin, etc. Users can add their own.

Such as / home/bin, etc.

Default path to the MANPATH man manual

INPUTRC default keyboard image, see / etc/inputrc for details

The environment variable of BASH_ENV bash shell, usually in ~ / .bashrc

The console applicable to the DISPLAY X window, and the DISPLAY=:0 corresponds to the console F7, which corresponds to the control.

The platform F8 sends GUI application programs to the remote computer.

The default terminal in COLORTERM GUI, usually gnome-terminal.

USER automatically sets the user name of the currently logged-in user.

LONGNAME is usually set to $USER

MAIL sets the standard mail directory for a specific $USR

Command output with HOSTNAME set to / bin/hostname

HISTSIZE is set to the number of commands remembered by the history command

Example:

#

# / etc/profile

#

# modify or add PATH to customize the search path of the command. If you do not want to add the executable file to the default directory, you can use it in the terminal.

# Ling, then change it.

Export PATH= "/ bin:/usr/bin:/sbin:/usr/sbin:/usr/X11R6/bin:/opt/bin:/usr/local/bin"

Export MANPATH= "/ usr/man:/usr/X11R6/man"

Export LESSCHARSET= "latin1"

Export INPUTRC= "/ etc/inputrc"

Export LESS= "- R"
