You should have asked about getting the pid of the new process then. As a matter of fact, you can, but as it says on the help page for "pid" you can't do it with exec. Use the "open" command to run the program and then use the "pid" command with the file handle that open returns to get the child process's pid.

set fp [open "|someprogram arg1 arg2" "r+"]
putserv "privmsg #sheep :pid of child is [pid $fp]"

You'll have to change your program some because open and exec work a bit differently.

means open also that it is executed ? ? or is that just a part of the proc file ?

Read the help page for "open"

Open can run a program just like exec, except it makes the other program run in the background.

So if you use open, you don't also use exec.

Read the part of the help page for open titled "COMMAND PIPELINES."

fileevent should work nicely if you configure the handle for nonblocking operations, or you can use a while loop with 'eof' and 'gets' to poll for it.

hmm i think i know what you mean and its not a while but it seems if i use open the eggy keeps open the file ... so wen it ends it is still running but .. the program is not active no more so .. ? maybe it is an error in the exe it self :/ don't realy know but it should close by it self .. :/ it normaly does, is it possible that the eggy keeps the file open ?
