Top Forums Shell Programming and Scripting Using output to input another command Post 302167367 by joeyg on Thursday 14th of February 2008 09:03:37 AM

Tools Use a for loop

#! /bin/bash

for zf in *myfile*.*
do
ls -l $zf
tail $zf
done

Notes:
(1) I do an ls command; not needed - just shows what file is being looked at in the loop
(2) tail is its own command line since guess you want to do more than simply execute this one command

This could all be done in one line as:
tail *myfile*.*
but, I figure this is part of something more complicated.
So, two choices.

NAME
mtail - tail variant designed for web developers monitoring logfiles SYNOPSIS
mtail [options] <file>... DESCRIPTION
MonkeyTail allows a user to tail multiple files on both local and remote hosts and clearly marks inactivity by putting 5 newlines in the output whenever a pause in output over 3 seconds is detected. MonkeyTail is implemented a fairly simple wrapper script around standard tail, ssh, and sudo. OPTIONS
-q Quiet mode --quiet " " -n Output the last N lines of each file before tailing (defaults to 0) <file>... Files to tail. These can specified in the following ways: @<groupname> - expands the group (from .mtailrc) to a list of files to tail <filename> - tails a local file. +<filename> - attempts to sudo and tail a local file (will prompt for pwd if required). <remotehost>:<filename> - attempts to invoke tail via ssh on a remote host. +<remotehost>:<filename> - attempts to invoke sudo tail via ssh on a remote host (will prompt for pwd if required).
