PT-ALIGN(1)	      User Contributed Perl Documentation	   PT-ALIGN(1)

NAME
       pt-align	- Align	output from other tools	to columns.

SYNOPSIS
       Usage: pt-align [FILES]

       pt-align	aligns output from other tools to columns.  If no FILES	are
       specified, STDIN	is read.

       If a tool prints	the following output,

	  DATABASE TABLE   ROWS
	  foo	   bar	    100
	  long_db_name table  1
	  another  long_name 500

       then pt-align reprints the output as,

	  DATABASE     TABLE	 ROWS
	  foo	       bar	  100
	  long_db_name table	    1
	  another      long_name  500

RISKS
       Percona Toolkit is mature, proven in the	real world, and	well tested,
       but all database	tools can pose a risk to the system and	the database
       server.	Before using this tool,	please:

       o   Read	the tool's documentation

       o   Review the tool's known "BUGS"

       o   Test	the tool on a non-production server

       o   Backup your production server and verify the	backups

DESCRIPTION
       pt-align	reads lines and	splits them into words.	 It counts how many
       words each line has, and	if there is one	number that predominates, it
       assumes this is the number of words in each line.  Then it discards all
       lines that don't	have that many words, and looks	at the 2nd line	that
       does.  It assumes this is the first non-header line.  Based on whether
       each word looks numeric or not, it decides on column alignment.
       Finally,	it goes	through	and decides how	wide each column should	be,
       and then	prints them out.

       This is useful for things like aligning the output of vmstat or iostat
       so it is	easier to read.
