In reply to Trevor Chandler. @Trevor, Yes, there is a difference! Using sudo strace -o df_debug.txt df -h directs strace to save all trace output (including errors) directly to df_debug.txt. In contrast, sudo strace df -h > df_debug.txt only redirects the standard output of the df command to the file, not the strace output. For capturing detailed tracing information, the -o switch is more effective.

On your #9 command example, is there any diiference and/or benefit in using the output redirection character (>), instead of the -o switch in the stace command?

sudo strace -o df_debug.txt df -h
vs.
sudo strace df -h > df_debug.txt

There are many duplicates of the output to each of your command examples.
