Setting the $PATH environment variable in Linux

To view the current path, either of the following commands work:

1.
$ echo $PATH

or

2.
$ set | grep PATH

To set the $PATH  environment variable in Linux (add a new directory to the current path while retaining the other directories):

$ export PATH=$PATH:<new_directory>

Below is a sample screen display:

$ echo $PATH
/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home/user/bin

$ export PATH=$PATH:/home/user/temp
$ echo $PATH
/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home/user/bin:/home/user/temp
