Trying to find instance of regex pattern ['“]rm[ ].*['”] using grep

Question

I'm trying to find lines similar to these input strings. Basically -a single or double quote -followed by 1 or more blanks -followed by rm -followed by 1 or more spaces

Below would be some example matches.

build2('rm myfile')
build2(" rm myfile')
'rm myfile'

I can use a regex tester like regexpal dot com and it works fine but how would I do it using grep if my input file is called myfile.txt? I've tried the command from shell prompt below but grep does nothing but response with a > character on the next line.

grep "['"] *rm *" myfile.txt

Answer 1

You use double quotes around your call to grep. Therefore, you need to escape the double quote inside your pattern.

grep "['\"] *rm *" myfile.txt
