I want to search all files in the current directory and below for the substring
$form['#node']. So, I have tried, initially:
grep -R "\$form\[\\\\'" . and
grep -R "\$form\[\'" .
But it returns no results. However,
grep -R "\$form\[" returns plenty of results, as there are instances of entries such as
$form['#node'] in the files. Is there any reason why adding the escaped single quote causes an issue? I can't seem to find any clear indication of exactly how to escape a single quote in this case.
I need to check that my escaped characters are working as intended in this scenario.
