What you are looking for is to set $| = 1; on the currently selected file handle (by default STDOUT). $| also known as $OUTPUT_AUTOFLUSH and also $AUTOFLUSH turns OFF buffering when set and so you will see the results of every print as it happens instead of when perl figures it's time to flush the output buffer. Buffering is ON in perl by default. If you are printing to STDOUT you have only to do a $| = 1; somewhere before your while loop. If you print to some other handle be sure to select(HANDLE); before you assign to $|, etc.

KILLALL5(8)						Linux System Administrator's Manual					       KILLALL5(8)

NAME
killall5 -- send a signal to all processes. SYNOPSIS
killall5 -signalnumber [-o omitpid[,omitpid..]] [-o omitpid[,omitpid..]..] DESCRIPTION
killall5 is the SystemV killall command. It sends a signal to all processes except kernel threads and the processes in its own session, so it won't kill the shell that is running the script it was called from. Its primary (only) use is in the rc scripts found in the /etc/init.d directory. OPTIONS
-o omitpid Tells killall5 to omit processes with that process id. NOTES
killall5 can also be invoked as pidof, which is simply a (symbolic) link to the killall5 program. EXIT STATUS
The program return zero if it killed processes. It return 2 if no process were killed, and 1 if it was unable to find any processes (/proc/ is missing). SEE ALSO
halt(8), reboot(8), pidof(8) AUTHOR
