Search files with grep

In a programmers live, you need a recursive file search nearly every day.

Of course, this is possible without a heavy IDE and with a simple but useful bash one liner:

$ grep "pattern" -HniR ./path/to/dir

The options in detail:

• H printing the filename of the match
• n print also the line number
• i for a case *in*sensitive search
• R for recursive

Of course, this can also be combined with grep regular expressions.
