<file>, file with the commands
-h, usage and options (this help)
-l, see this script"
This script is useful in a situation when one has to regularly run
multiple commands that are listed in a file and may have to stop the
execution of the file before all commands are done executing. Upon
next execution of the file, to avoid re-running the already run
commands, one would have to manually re-arrange the commands.
This script eliminates the need for that, as it acts as a wrapper to
the commands listed in a file.
If the execution of this script is interrupted, the commands stored in a
file get rotated, so the commands which have already been executed will
be appended to the end of the file. The only command that will be re
executed is the one which did not finish running when the file execution
The last command in file must be terminated by a new line character.
