Bash script that will pop a line item for a file and pass it to a command.

process_params.sh

#!/bin/bash

echo "Starting..."

param=`sed -e 1$'{w/dev/stdout\n;d}' -i~ params.out`

while [[ -n $param ]]; do
	echo "Starting process for $param..."
	<some-command> $param &
	curr_pid=`echo $!`
	echo "Current pid is $curr_pid"
	is_running="yes_it_is"
	while [[ -n $is_running ]]; do
		echo "Sleeping..."
		sleep 5s
		is_running=`ps -ww -fp "$curr_pid" | grep <some-useful-regex-for-command>`
		#echo "debug: $is_running"
	done
	echo "Last process for $param completed!"
	echo "Popping next param..."
	param=`sed -e 1$'{w/dev/stdout\n;d}' -i~ params.out`
done

echo "Done!"

TODO

• Have <some-command> pass in as command line arg to this script.
• Have <some-useful-regex-for-command> pass in as command line arg to this script.
• DRY this script, i.e. move duplicated code to function(s).
