Linux – find files containing specific text

Handy command on Linux/Mac to find all files matching a pattern containing a specific text. This will also print file name.

$ find . -type f -name "*.php" -exec grep -H foo {} \;
./dir1/file1.php:function foo () {
./dir1/file2.php:foo();

Few points to note

1. grep -H causes the command to print file name
2. -type f will only run the command (specified by -exec) on files
3. {} gets filled with file name.
4. Backslash before semicolon (\;) is used to protect it from shell interpretation.
