How do I recursively grep all directories and subdirectories?
find . | xargs grep "texthere" *
2
grep -r "texthere" .
The first parameter represents the regular expression to search for, while the second one represents the directory that should be searched. In this case, . means the current directory.
Note: This works for GNU grep, and on some platforms like Solaris you must specifically use GNU grep as opposed to legacy implementation. For Solaris this is the ggrep command.
