use $!
Use $! to get the pid of the last background process. $$ gives the pid of the current executing process. So, basically you are killing the process that has started the timer.ksh(the parent process). And so all processes get killed.

What is the best way for a parent to kill a child thread that has blocked on a command it cannot finish and will never read another line of its code? Will pthread_cancel() work with a thread that will never stop processing its current line of code? Thanks. (4 Replies)

pid(n) Tcl Built-In Commands pid(n)
__________________________________________________________________________________________________________________________________________________
NAME
pid - Retrieve process identifiers
SYNOPSIS
pid ?fileId?
_________________________________________________________________
DESCRIPTION
If the fileId argument is given then it should normally refer to a process pipeline created with the open command. In this case the pid
command will return a list whose elements are the process identifiers of all the processes in the pipeline, in order. The list will be
empty if fileId refers to an open file that is not a process pipeline. If no fileId argument is given then pid returns the process identi-
fier of the current process. All process identifiers are returned as decimal strings.
EXAMPLE
Print process information about the processes in a pipeline using the SysV ps program before reading the output of that pipeline:
set pipeline [open "| zcat somefile.gz | grep foobar | sort -u"]
# Print process information
exec ps -fp [pid $pipeline] >@stdout
# Print a separator and then the output of the pipeline
puts [string repeat - 70]
puts [read $pipeline]
close $pipeline
