Bash OR operator
My script is working with this:
if pgrep -f "/home/tiger/bin/pymp" >/dev/null 2>&1 ; then
I want it to check for mpv2 also.
This is what I have so far:
if [[ /usr/bin/pgrep -f "/home/tiger/bin/pymp" ]] || [[ /usr/bin/pgrep -f "/usr/bin/mpv2" ]] >/dev/null 2>&1; then
These are the errors I'm seeing:
/home/tiger/bin/pauseMusic.sh: line 3: conditional binary operator expected
/home/tiger/bin/pauseMusic.sh: line 3: syntax error near -f'if [[ /usr/bin/pgrep -f "/home/tiger/bin/pymp" ]] || [[ /usr/bin/pgrep -f "/usr/bin/mpv2" ]] >/dev/null 2>&1; then'

The [[ and ]] operators are for explicit comparative tests. If you want to check two command results, just use the shell:
$ if /usr/bin/pgrep -fq "/home/tiger/bin/pymp" || /usr/bin/pgrep -fq "/usr/bin/mpv2" ; then do_stuff; fi
Not all versions of pgrep support the -q argument to suppress output. If this is the case for you, you can suppress each pgrep individually or combine the redirection:
$ if { /usr/bin/pgrep -f "/home/tiger/bin/pymp" || /usr/bin/pgrep -f "/usr/bin/mpv2";} > /dev/null 2>&1 then do_stuff; fi
or
$ if /usr/bin/pgrep -f "/home/tiger/bin/pymp" > /dev/null 2>&1 || /usr/bin/pgrep -f "/usr/bin/mpv2" > /dev/null 2>&1 ; then do_stuff; fi
