Is there any way to check the first $NUM chars of a variable?
For example if I have a veriable which contains
VAR="LONGMORE LTD"
Can i check the first character begins with L?

With ksh93, bash, zsh:
For old shells use case:
[[ $VAR == L* ]]&&echo OK||echo KO
For old shells use case:
case $VAR in L*) echo OK;;*)echo KO;;esac

Hey there,
If you need to be more generic (like sometimes you want to match the first 3 letters and sometimes 2, etc) you can use expr's : (colon) operator to do string and substring matching.
Hope that helps,
Mike
