here is the output when i try to execute as a non-root user:
./javathreads: line 2: /home/proc_threads/tempfile: Permission denied awk: cmd. line:1: fatal: cannot open file `/home/proc_threads/tempfile' for reading (Permission denied)
The script is running, but the 'awk' line is failing to read /home/proc_threads/tempfile. What are the permissions on that file and directory?
$ ls -ld /home/proc_threads $ ls -l /home/proc_threads/tempfileUnless you have some other use for the contents of tempfile, you could use a pipeline instead to avoid any permissions issue.
If you don't mind, I would like to see the pipeline equivalent. :)
ps -C java -o thcount | awk ' { total += $1 } END { print total } '
Now, as dearly as I love awk, ps -C java --no-heading | wc -l
