I want to argue with Asher.

I really ought to learn bash scripting.

That's another thing about shells. Helpful for automation.

Eg, here's a script I combine with a cron job at work (cron job = triggered on a timer, in this case at 3am). It restarts a server process, and in the event of any problems automatically emails an onduty tech or pages someone if unavailable.

#! /bin/csh -f

if ( $#argv != 1 ) then
    echo " "
    echo "WRONG NUMBER OF ARGUMENTS GIVEN : Please use the following syntax:"
      echo "earlyMorningProcessRestarter.csh (true or false)"
    echo "If the argument is true, the process checker will restart the server processes. "
    echo "If the argument is false, the processes will be checked, and support will be paged if down."
else

    setenv restartBackend $1
    #st_checkprocesswrapper.csh > /tmp/LatestProcessCheck.results
    grep /bin/gss /tmp/LatestProcessCheck.results > /tmp/LatestGSSCheck.results

    if ( $restartBackend == 'true' ) then

        if (  `grep -c '* NOT RUNNING'  /tmp/LatestProcessCheck.results` == 0 )
then
            echo "Processes on `hostname` are all up and running.  No need to restart at `date`.";

        else if ( `grep -c '* NOT RUNNING'  /tmp/LatestProcessCheck.results` == 1 &&  `grep -c '* NOT RUNNING'  /tmp/LatestGSSCheck.results` == 1 ) then
            echo " gss not running - but ok : No need to restart  at `date`."

        else
            cat /tmp/LatestProcessCheck.results | mail (censored)
            echo "Restarting on `hostname` at `date`" | mail (censored)
            /home/lnstprod/utils/ldn_intradayrestart.csh lnstprod

        endif

    else if ( $restartBackend == 'false' ) then

        if (  `grep -c '* NOT RUNNING'  /tmp/LatestProcessCheck.results` == 0 ) then
            echo "Processes on `hostname` are all up and running.  No need to page (censored) at `date`.";

        else if (  `grep -c '* NOT RUNNING'  /tmp/LatestProcessCheck.results` == 1 &&  `grep -c '* NOT RUNNING'   /tmp/LatestGSSCheck.results` == 1 ) then
            echo " gss not running - but ok : No need to page (censored) at `date`."

        else
            /opt/bin/bing eu-fit-middle-office "Server Processes not running on `hostname` please see email"
            cat  /tmp/LatestProcessCheck.results | mail (censored)
        endif

    else
        echo " "
        echo "INVALID ARGUMENT GIVEN "
    endif
endif

Here's an obvious one.

Search and replace in text files...

I think I already said this, but I don't use my computer for much more than word processing, web browsing, and game playing; so I'm going to throw something out here and see if it makes any sense.

Could such a tool (or a similar tool) be used to... say... collectively modify the meta-data on all my music files so that they adhere to some uniform standard that works with how I want to organize them?

[Asher]

Yes, provided you can find a tool to modify meta-data of music files.

Such a thing is likely to contain logic, and is thus better implemented like a script I have above.

An easier solution is to use an existing tool that already does that, eg Mp3tag
