ksh case structure
Hello Experts,

I ve been trying to build another shell where I am using the following code.

Code:
 
transact="tv5cpc1"
 
case "$transact" in
  "...cp..")
   xActType=""
   ;;
  "...de..")
   xActType="sp_dep"
   ;;
  "...ep..")
   xActType="sp_epa"
   ;;
  "....v.")
   xActType="sp_pt"
   ;;
  *)
   xActType="NA"
   ;;
  esac

The problem I am facing is that it always comes to the default case and not any of the cases above it. I believe their is some mistake in the way I have given the Regular Expressions for cases.

Please hint towards the mistake.

Regards

You need question marks '?' instead of dots '.' in the patterns.

reason?
Hello Radoulov,

Ok, "?" solves the problem, thanks Smilie.
Could you please tell the reason for that! A "." would match any single character, right?

Regards

You're confusing shell patterns with regular expressions.
The dot '.' is a regular character whenever patterns are processed.

Thanks Radoulov.
And thanks for the pointer to the "pattern" and "regEx" difference(I would ve liked it if you would ve given this as first reply and not directly telling me about "?". Would help me learn more Smilie ).

Regards
