Rudimentary Shell Events

Sometimes I want commands in one terminal to happen only after commands in another terminal have finished.

This is a temporary solution to a problem likely better solved by someone else somewhere :)

Usage

In one terminal:

$> on someEvent ; echo done!

In the other:

$> some_long_process ; trigger someEvent

This will cause the first terminal to halt until some_long_process has finished.

on.sh

#!/bin/sh

##
#
# Very basic shell event listener (still needs proper work)
#
# TODO: support multiple instances of events
# TODO: usage text / help
#
##

fname=/tmp/event_$1.txt

while [ ! -f "$fname" ]
do
	# echo waiting...
	sleep 2
done

rm $fname

trigger.sh

#!/bin/bash

##

# Very basic shell event trigger (still needs proper work)

fname=/tmp/event_$1.txt

touch $fname
