How to increase executions speed of loops.?

I have a small script that loops through all files of a folder and executes a (usually long lasting) command. Basically it's

for file in ./folder/*; do ./bin/myProgram $file > ./done/$file done

(Please Ignore syntax errors, it's just pseudo code).

I now wanted to run this script twice at the same time. Obviously, the execution is unnecessary if ./done/$file exists.

Hi, I'm having problems with a script which some of you helped me with last week. It's a script to check the status of orders in an SQL database, and if the count(*) is zero, then the script stops.

Is there a way to specify multiple variables (not just integers) in for loops in bash? I may have 2 files containing arbitrary text that i would need to work with.

What i functionally need is something like this:

for i in $(cat file1) and j in $(cat file2); do command $i $j; done

Any ideas?

Hi I have to write a shell script which copy files from one folder to another. When I try to do it directly from command prompt cp filename.dat /outgoing/filename.dat its working fine. But when I put the same command inside a shell script say test.sh its not getting copied. and when I check $?
