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

 |=====================================================================================|
 |    Aurt, a tiny AUR helper script.         USAGE:  $ aurt [operation] [package]     |
 |-------------------------------------------------------------------------------------|
 | -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:
https:bbs.archlinux.org/viewtopic.php?id=232437

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.

sysstat

SYSSTAT(5)							Linux User's Manual							SYSSTAT(5)

NAME

       sysstat - sysstat configuration file.

DESCRIPTION

       This  file is read by sa1(8) and sa2(8) shell scripts from the sysstat's set of tools.  It consists of a sequence of shell variable assign-
       ments used to configure sysstat logging.  The variables and their meanings are:

       HISTORY
	      The number of days during which a daily data file or a report should be kept. Data files or reports older than this number  of  days
	      will be removed by the sa2(8) shell script.

       COMPRESSAFTER
	      Number of days after which daily data files are to be compressed, either by gzip or bzip2.

       SADC_OPTIONS
	      Options  that  should be passed to sadc(8).  With these options (see sadc(8) manual page), you can select some additional data which
	      are going to be saved in daily data files.  These options are used only when a new data file is created. They will be  ignored  with
	      an already existing one.

FILES

       /etc/sysconfig/sysstat
