experts,
I just started to study about the shell script.
And I was reading a stackoverflow page: 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!

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