Hi, try (using bash or ksh93) :

Code:
while IFS=: read val key
do
  if [ "$key" = "$INPUT" ]; then
    echo "$val"
  fi
done <<< "${VAR//,/$'\n'}"



Code:
$ INPUT=aaa
$ while IFS=: read val key; do   if [ "$key" = "$INPUT" ]; then     echo "$val";   fi; done <<< "${VAR//,/$'\n'}"

$ INPUT=bbb
$ while IFS=: read val key; do   if [ "$key" = "$INPUT" ]; then     echo "$val";   fi; done <<< "${VAR//,/$'\n'}"
