i need a help with a script (duh!)
the script is supposed to open 2 files with "tailf -f" or some eggdrop/tcl built-in function, and check each line in a if,
now to the problem, woun't the bot freeze all it's other functions while checking the files?

it would if you used exec tail -f, exec is a blocking function.

No.

Eggdrop is not threaded, and thus, it has to block/freeze to perform the action.

It all depends what the script/exec will be doing. As you maybe able to speed things up, without the use of tailf.

You can do it 2 ways. You can either use a pipe instead of exec (read the 'open' command) and use non-blocking io on the pipe (see 'filevent').

Or you can write the whole thing in Tcl (use the 'file' command to monitor the access time, then just seek to the end and get the new data).

Thanks for the help, but i solved it in another weird way

learned C and coded my own crapy bot (with threads) just for this function
