Thanks for taking the time to comment.

Multiple arguments could be added if you want that. I personally do not need it as I search the cmdline patterns I need without using spaces. I use dots instead. Quick and dirty.

I write 100's of these small scripts for my own use only so I have my own style, peculiar as it may be. I never need indentation because I always keep scripts short; I only use it occasionally and randomly.

I do not use -e with sed, unless I'm using branches or loops.

The execs seem superfluous but actually make a difference, at least on the UNIX I use. Try it with and without and see if you notice.

All my scripts are portable to Bash, but they're also portable to the most basic of Bourne-compatible shells too. I do not use Bash.
