Triggering when a proc has finished...

Is there anything that can trigger 1 proc as soon as the previous proc has finished?

Yes, make the last command in the proc, a call to the next one.

proc first_proc {arg1 arg2} {
 code1
 code2
 code3
 second_proc $arg1 $arg2
}

proc second_proc {arg1 arg2} {
 command
 command
}

Yes, but I am using lftp inside the tcl script, and is there any way of making it start the next proc, when lftp has stopped listing the dir?

You could use vwait. Set trigger 0
then after issuing the list command, issue a vwait on trigger. Then after listing has completed, set trigger 1.

The concept is demonstrated here:

That will not work with lftp because it is lftp that is doing the listing, and u cant set the listing to a variable...
The list is ouputted to a txt file!

how exactly is lftp being called from the proc in the first place?
