Greetings all; I am as you have proably guessed by now, the originator of some bash scripts that greatly simplify the day to day background operations.
Two of these "scripts" make use of inotifywait to hand them the data they need to do the rest of their jobs. One of them watches /var/spool/mail and is dependent on finding the $pidof kmail so it kmail isn't running, it will not send a message to kmail over the dcop or dbus facility and thereby stuffing up the buffers either of these use. However, there are generally two instances of inotifywait running because I also use a session to watch another directory where a .jar file running as drivewire for a legacy computer in the basement, so that I can send a file to a printer it thinks is attached to that machine, but which in reality is actually sent up the usb cable to this machine and dropped into a file here. Simplified, that file, when closed by drivewire, is then sent via an lp command in that script, thru cups which renders it, then sends it back down that same usb cable to a brother B&W laser printer on that computers desk, where it gets spit out in a beautiful font, at 19 ppm, which is about 20x faster than any pin pounder printer that was ever connected to it 30 years ago. However, if something goes aglay, my scripts try to kill the inotifywait session, and go silent until the proper $pidof's are present again. But occasionally they will kill each others inotifywait sessions as I am currently doing that kill with killall $name. Not the correct way obviously to kill the session that THAT script started. Because inotifywait is not silent when it launches, I have been forced to do an "var=inotifywait $option_string 2>&1 >/dev/null &" to absorb the noise. Am I dumping the PID return? Can I save that launch return and use it to do a specific "kill $savedvar"? The manpage for inotifywait is silent in this regard, but I suspect I am looking at the wrong manpage. Perhaps, since its a bash script in both cases, its the bash manual I should be studying? Thanks for any clues. The bash manual, at around 500 pages, details aren't that easy to find in that tome.
