Top Forums Shell Programming and Scripting PERL - Use of uninitialized value in pattern match (m//) Post 302938642 by balajesuri on Wednesday 18th of March 2015 07:03:48 AM

I think this is what you mean:
Code:
   for $line (<FILE>) {
      if ($line =~ /(.....)\//) {
        $participant = $1;
      }
      print "$participant";
   }
   close(FILE)

And don't close(FILE) inside the for-loop. If you do so, perl will not be able to read from the file in next iteration.

continue(3tcl)						       Tcl Built-In Commands						    continue(3tcl)

__________________________________________________________________________________________________________________________________________________

NAME
continue - Skip to the next iteration of a loop SYNOPSIS
continue _________________________________________________________________ DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_CONTINUE code, which causes a continue exception to occur. The exception causes the current script to be aborted out to the innermost containing loop command, which then continues with the next iteration of the loop. Catch exceptions are also handled in a few other situations, such as the catch command and the outermost scripts of procedure bodies. EXAMPLE
Print a line for each of the integers from 0 to 10 except 5: for {set x 0} {$x<10} {incr x} { if {$x == 5} { continue } puts "x is $x" } SEE ALSO
break(3tcl), for(3tcl), foreach(3tcl), return(3tcl), while(3tcl) KEYWORDS
continue, iteration, loop Tcl continue(3tcl)
