Hi all.

I have a little bash script that simply outputs "foo" into a file under the /tmp dir

!#/bin/bash
echo foo &> /tmp/foo.txt
exit $?

A little thing about this code is that I'm executing it thought "C"'s "execl" command. It works fine the first time...but then hangs the second....if I kill the process and leave it for a while, it will work again...once...and then hang until I kill.

I think that there is a combat for resources here and that either the bash script or the C script is tieing up the I/O Stream....I have reason to believe it's the bash...although I've been wrong many...many times before. ^_^

Long story short, is there any way to "flush" out the I/O stream in bash?

Thanks in advance! ^_^
