Could you be more precise ? As far I know 'forking' is an action to create a child process from a main program

There isn't a program [Ff][Oo][Rr][Kk] on neither Slackware 9.1 or 10.0. I have a full install (including extra packages) of both on different partitions and the only thing I can find is a help file from tclX.

Are you talking about this? http://sourceforge.net/projects/fork/

aha yes, thats the sourceforge link i was after,
fork is a program used to execute a command detached from the shell, the shell recieves NO messages from it..
it's commonly used in webserver environments(as i'm using it for) and also is used during startup-scripts ofccasionally if the process is going to take along time to execute, yes the system must still continue to boot regardless.

thansk for the link, i don't knowwhy i didn't find it myself...

bash supports forking internaly :

#!/bin/bash
updatedb &
echo "I actually display this message while updatedb is running

"

If you use &, you DO get messages from the program (if it outputs any of course..

).

no, if you use the null device :
command 1> /dev/null 2> /dev/null &

Yes, you have a choice of the above or using fork, personally, fork is a little quicker to type in :)

Ok so :

Code:

#!/bin/bash
exec $1 1> /dev/null 2> /dev/null &

Save it at /usr/bin/fork and chmod +x it

Oh shush you :D - that's probably all fork is, a two line shell script :P!

To be honest, I just did add it to my /usr/bin,

cheers ;)
