MTAIL(1)							   User Commands							  MTAIL(1)

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).
