Took me some time to get there... But i did. For future owners searching for this here it is.

The simplest way is to use bgexec scripts. I used the one caeser posted, but there are others online.

To launch your code use:

Code:

bgexec "lftp -f script.txt" callback

To catch the response from lftp use:

Code:

proc callback {input} {foreach line [split $input "\n"] {putlog "$line"}}

Tks for your help caesar.

Following you hint i came this far:

Code:

set lftpexe [open "|lftp -f script.txt"]fconfigure $lftpexe -blocking 0fileevent $lftpexe readable [list lftpcallback $lftpexe]proc lftpcallback {lftpexe} {putlog "Reader"gets $lftpexe splineputlog "Read: $spline"}

Its not working since i get like 10 "Reader" and "Read:" in each second and after a while the lftp process appears as "defunct". From what i understood it means there's something to be read before the precess ends.

I think i may need to close channel inside lftpcallback, but didnt have the time to test it.

3rd option my guess would be to use fileevent with a callback to another proc.

Anyway, I haven't done this before but I recall there was a topic regarding the same issue, like this one. Or you could search the forum with fileevent as keyword.

I've been coding a script to transfer some files using lftp. Lftp is launched with exec. From what i searched in this forum seems i have two options:

1- Run exec and wait for transfer to finish and get a sucess return code or failed. In the meanwhile the eggdrop stops responding and if the transfer takes long enough it will timeout from IRC.

2- Run exec in the backgroud and forget about any sucess confirmation or error handling.

Is there a 3rd option?
