What is file descriptor 10?
Real-world example (where standard output is ignored, standard error redirected to standard output and data from file descriptor 10 is redirected to standard output) that I have lost the documentation/context for:
./cluexec21nodes 'mkdir /home/mortense/sambapub;cd /home/mortense/sambapub;./runcola.sh >/dev/null 2>&1 10>&1 &'
0 Standard Input (stdin) 1 Standard Output (stdout) 2 Standard Error (stderr)
but what is file descriptor 10?
This was used on a Linux system (possibly Red Hat).
