terminate program

How do I end my perl script in the middle, if I check and see the input is wrong and i want to end the program

like exit(1); in C

RE: terminate program

pretty simple....

if (some condition) { exit; }

or, if you would like to print to STDOUT on the way out
if (some condition) { die "Failed the condition\n"; }

# you often use die to get out after failure to do something you
# needed to do, like open a file
open(IPF,"<input_File_name") or die "Failed to open input file, $!\n";

'hope this helps.

RE: terminate program

goBoating, doesn't die print to STDERR, not STDOUT?

RE: terminate program

Note: because die prints to STDERR and not STDOUT, if you are using it in a cgi script whatever you print that way will usually NOT show up! My solution was to write a CgiError subroutine which takes an error message and prints an html page showing the error message and then exits. This achieves the same end, but allows you to display the error in the browser.
