grep -v is not excluding the strings (I figured it out in my answer)












-1














im trying to narrow down a flag to catch by removing strings with certain unwanted words so i use



cat $(find / -size 33c -group bandit6 -user bandit7) | grep -v 'Permission'


but my results end up being

so it appears to $() was the problem



cat $(find / -size 33c -group bandit6 -user bandit7) 2>/dev/null


will not work, however



cat $(find / -size 33c -group bandit6 -user bandit7 2>/dev/null)


will work
i imagine grep -v may work with some mixture of stderr inside the brackets aswell
