Long summary:
The following are two examples of a simple shell script. As the reader can see, this is a
series of commands to change to the userâ s $HOME directory, create a subdirectory, and
print out the line from the env command containing the string PATH; the reader could
execute these same series of commands from the command line.
n assigning a variable, there is no whitespace around the â =â operator. export changes
an ordinary shell variable into an environment variable, which is passed to subshells or
child shells.
The value of a shell variable is referenced by prepending a â $â to the name. Note that
using double quotes (") or grav´e quotes ( ) expands to the variableâ s value before its use
whereas escaping the â $â or using single quotes (´) does not.
