How To Read / Print $PATH Shell Variable

Q. I’m new to Unix / Linux and I’d like to print current values of $PATH variable. How do I read $PATH from a shell prompt?

A. To read or print any shell variable value use echo command.

Display a line of text

Use the command as follows to display message ‘This is a test’ on screen:
echo 'This is a test'

Display $PATH values

Type the command as follows:
echo $VAR_NAME
echo $PATH
Sample output:

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
