List processing with bash

Just a simple example of a bash script to process items found in a list. [code language="bash" gutter="false"] #!/bin/bash INPUT=/data/tmp/just-users.txt OLDIFS=$IFS IFS=, [! -f $INPUT] && { echo "$INPUT file not found"; exit 99; } while read uid do THUMBEXT=".jpg" PROFEXT="_profile.jpg" echo "$uid$THUMBEXT" echo "$uid$PROFEXT" done < $INPUT IFS=$OLDIFS [/code] This script takes a list of uid values and appends text to form an image name.
