Question. How do I add new path to PATH variable under Linux and UNIX operating system?
Answer. The syntax for setting path under UNIX / Linux dependent on which shell you are using. BASH / SH shell uses following syntax:
export PATH=$PATH:/path/to/dir1:/path/to/dir2
For tcsh or csh, shell enter:
set PATH = ($PATH /path/to/dir1 /path/to/dir2)
You
can type above command at the terminal or add it to your .bashrc (for
BASH/sh shell) or .cshrc (for chs / tcsh shell) so that PATH can be set
each time you login into box. For example add /usr/local/bin to your
path under BASH, enter:
export PATH=$PATH:/usr/local/bin
Or add as follows to your .bashrc file:
echo 'export PATH=$PATH:/usr/local/bin' >> ~/.bashrc
If you are using CSH / TCSH, enter:
echo 'set PATH = ($PATH /usr/local/bin /scripts/admin)' >> ~/.cshrc
To display path settings, enter:
$ echo $PATH
