Hello,

I'm having a problem with bash, tr, or echo... I'm not sure who the culprit
is here. In any case, here's a short script:

>#!/bin/sh
>
>OPTIONS="A B C"
>
>FOUND="FALSE"
>FIND=`echo a | tr '[a-z]' '[A-Z]'`
>
>echo $FIND
>
>for opt in $OPTIONS ; do
>  if [ $opt = $FIND ] ; then
>    FOUND="TRUE"
>  fi
>done
>
>echo $FOUND
>

What it should echo at the end is TRUE since 'A' is in "A B C".
But it echos FALSE. Note, that this works on my UNIX box. Also, if I say
FIND=`echo A | tr '[a-z'] '[A-Z]'` that fails also.

Thanks,
