Hello, I have the log file from squid. The second file is IP_text (one IP address per line) now I'd like to select all lines from log_file that contains one of the IP's in IP_text file and put that all in third file. Something like cat access.log|grep `cat IP_text` but that does't work :-( Any idea THX Janez -- \\\___/// \\ - - // ( @ @ ) +-----------------------oOOo-(_)-oOOo---------------------------+ | | | KONTRANET: WWW.KUD-KONTRABANT.SI | | WWW.KONTRABANT.COM | | | | Janez Vrenjak | | janez@kud-kontrabant.si janez@kontrabant.com | | | | tel.: +386-(0)1-7227 595 | | +386-(0)61-172 40 11 | | +386-(0)41-571 440 | | | +------------------------------------Oooo-----------------------+ oooO ( ) ( ) ) / \ ( (_/ \_) If you don't like the way I drive, stay off the sidewalk! - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.rutgers.edu
