Exiting a program! - perl
how would you exit out of a programm correctly, without having for the program to crash?

for example
Code:
print "Enter quit";
$input = <STDIN>;

if ($input eq "quit")
{
  {QUIT THE PROGRAM}
}
else 
{
  print "invalid input";
}

one more thing, how do u exit a program "correctly", if the user unexpectedly closes the program?

thanks

thanks birei,

instead of starting a new thread, do u happen to know, how to list files in a specific shell wildcard, so for example,
Code:
print "Enter a pattern (The pattern has to be in [])";
$input = <STDIN>;

if ($input is in [])
{
  list files with the specific file pattern;
}
else
{
  print "invalid input!";
}

I appreciate your help!!

Use 'glob' function.

For help:
Code:
$ perldoc -f glob
