Thanks for replies.

Second time someone asked why not using getopts. I have not looked into it so far, although I probably should.

With manually parsing options, I consider each argument as an operation rather than an option. No real option ability...

When the program is called with no operations, or a non existent op, they get this or in the former, without the error message.:

Code:
$ aurt -qR

  Input Error: Please try again or see    aurt --help

 |-------------------------------------------------------------------------------------|
 | -S  Install Update                -F  Files Provided By Pkg          NOTES:         |
 | -Sv Update By Version             -s  Search For Pkg                                |
 | -Sf Force Install Update          -p  Pacman Log                                    |
 | -R  Remove Pkg And Bld Dir        -h  Help                      leafpad-aurt: lat   |
 | -C  Ck All Pkgs For Updates                                  thunar-base dir: tbd   |
 | -D  Package Dependency Details                              Orphans:  R $(p -Qtdq)  |
 |=====================================================================================|

The scripts:
Code:

I was contemplating using the --quiet "option" with the -S and -Sv operations only, as the rest couldn't use --quiet.

I read getopts will not take long options? My script needs the ability to process package names, ie: aurt -S <package name> That and manually parsing them seemed more straight forward to me when I started, likely because of my inexperience.

At this point, it sounds like I need to get my head around understanding getopts and figure out how to deal with the program names separately?

Just reading the replies from you guys gives my more things to research, test, and think about.

The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
