[SOLVED] shell script question: { set +x; } 2>/dev/null

Issue

experts,

I just started to study about the shell script.

And I was reading a stackoverflow page: href="https://stackoverflow.com/questions/13195655/bash-set-x-without-it-being-printed">Bash set +x without it being printed

My question is simple as you see:

{ set +x; } 2>/dev/null

On the shell script, what does the '{ set +x; }' mean?

I already got the answers about the "2>/dev/null" so far.

but I cannot find any idea about the "{set +x;}" but "set -x".

Please teach me what it is.

Thank you!

Solution

set -x enable a mode, that prints all executed commands to the terminal.

set +x disables this mode.
