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

       The following section is included to inform users about the potential risks, whether known or unknown, of using this tool.  The two main
       categories of risks are those created by the nature of the tool (e.g. read-only tools vs. read-write tools) and those created by bugs.

       pt-align is a read-only tool.  It should be very low-risk.

       At the time of this release, we know of no bugs that could cause serious harm to users.

       The authoritative source for updated information is always the online issue tracking system.  Issues that affect this tool will be marked
       as such.  You can see a list of such issues at the following URL: http://www.percona.com/bugs/pt-align <http://www.percona.com/bugs/pt-
       align>.

       See also "BUGS" for more information on filing bugs and getting help.

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.
