Linux --- set the command search path

Linux-set the command search path-Linux general technology-Linux programming and kernel information. For more information, see the following. Use echo $ PATH

The $ PATH variable is displayed, and the output is as follows:
/Usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11: /usr/games:/usr/X11R6/bin

It is an environment variable that represents the Shell search path when the command is executed.

When executing a command, Shell searches for the PATH defined by the $ PATH variable and runs an executable file with the same name as the command. If the executable files such as programs and scripts are not in the above path, you must use the absolute path or relative path to locate the executable file.

For example:
/Usr/local/mplayer-menu xxx. rmvb
/Etc/init. d/powernowd start
Cd/usr/local/&./mplayer-menu xxx. rmvb

You can modify the/etc/environment file to set your command search PATH and find the starting line of PATH.
PATH = "/usr/local/sbin:/usr/local/bin:/usr/sbin"

Add your custom path in double quotation marks and separate them.
