[Solved] If doesn't evaluate the first test
Good afternoon,
I am tearing hair out over this. It should be so simple. I have an if statement to evaluate whether or not replication is working. I am testing variables from mysql to see if they are both "Yes". I have put some echo statements in to see how far the code proceeds. It always seems to skip the initial test (or evaluate it as false) and run to the end of the script. I could really use another pair of eyes on this.
Thanks
Jim

Code:
#!/bin/bash

# variables
host="ipaddr"
user="user"
pass="password"
var="Yes"

#Connect
out=$(mysql -h $host -u$user -p$pass -se "show slave status")
echo $out > /tmp/working.txt
awk '{print$11, $12, $16, $17, $19, $20}' /tmp/working.txt >> /tmp/variables
rm -f /tmp/working.txt
read log pos io sql error query < /tmp/variables

echo $io $sql

if [$io = "Yes" -a $sql = $var]; then
rm -f /tmp/variables
echo "made 1"
        else
mail -s "replication broke" email@gmail.com < /tmp/variables
echo "hit 2"
fi
rm -f /tmp/variables
echo "done"

xfs_estimate

xfs_estimate(8) 					      System Manager's Manual						   xfs_estimate(8)

NAME

       xfs_estimate - estimate the space that an XFS filesystem will take

SYNOPSIS

       xfs_estimate [ -h? ] [ -b blocksize ] [ -i logsize ]
		    [ -e logsize ] [ -v ] directory ...

DESCRIPTION

       For  each directory argument, xfs_estimate estimates the space that directory would take if it were copied to an XFS filesystem.  xfs_esti-
       mate does not cross mount points.  The following definitions are used:
	      KB = *1024
	      MB = *1024*1024
	      GB = *1024*1024*1024

       The xfs_estimate options are:

       -b blocksize
	      Use blocksize instead of the default blocksize of 4096 bytes.  The modifier k can be used after the number to  indicate  multiplica-
	      tion by 1024.  For example,

		   xfs_estimate -b 64k /

	      requests an estimate of the space required by the directory / on an XFS filesystem using a blocksize of 64K (65536) bytes.

       -v     Display more information, formatted.

       -h     Display usage message.

       -?     Display usage message.

       -i, -e logsize
	      Use  logsize instead of the default log size of 1000 blocks.  -i refers to an internal log, while -e refers to an external log.  The
	      modifiers k or m can be used after the number to indicate multiplication by 1024 or 1048576, respectively.

	      For example,

		   xfs_estimate -i 1m /

	      requests an estimate of the space required by the directory / on an XFS filesystem using an internal log of 1 megabyte.

EXAMPLES

       % xfs_estimate -e 10m /var/tmp
       /var/tmp will take about 4.2 megabytes
	       with the external log using 2560 blocks or about 10.0 megabytes

       % xfs_estimate -v -e 10m /var/tmp
       directory		     bsize   blocks    megabytes    logsize
       /var/tmp 		      4096	792	   4.0MB   10485760

       % xfs_estimate -v /var/tmp
       directory		     bsize   blocks    megabytes    logsize
       /var/tmp 		      4096     3352	  14.0MB   10485760

       % xfs_estimate /var/tmp
       /var/tmp will take about 14.0 megabytes
