Programa búsqueda de texto en archivoa

Quisiera saber de algún programa similar a fileseek o searchmonkey, para encontrar cadenas de texto dentro de los archivos de un directorio.

Hi, i would recommend you to use the command line to do so - the command in question is grep. Example:

cd ~/Documents
grep -irl  -E "([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})" *

This will search all documents in the Documents folder for valid E-Mail Adresses and print out each file containing one. Regular Expressions may seem complex at first but are extremely versatile. If you just want to search for a simple Text string, just enter it as it is.
