While loop to test if a file exists in bash
...e file actually exists by adding:
while [ ! -f /tmp/list.txt ]
do
sleep 2 # or less like 0.2
done
ls -l /tmp/list.txt
You might also make sure that you're using a Bash (or related) shell by typing 'echo $SHELL'. I think that CSH and TCSH use a slightly different semantic for this loop.
