Need to suppress rowcount headers when using \G
I have two suggestions

SUGGESTION #1 : Use grep command

You could use the grep command to filter it out

mysql -u... -p... -ANe"SHOW SLAVE STATUS\G" | grep -v "^\*\*\*\*\*\*\*\*\*"


Here is a quick demonstration:

[root@***** ~]# mysql -uroot -p... -ANe"SHOW SLAVE STATUS\G"

SUGGESTION #2 : Use tail command (if expecting one row of output)

Run the \G command to a text file. Use tail to print everything but the first line:

[root@***** ~]# mysql -uroot -p -ANe"SHOW SLAVE STATUS\G" &gt; junk.txt
[root@***** ~]# LINECOUNT=`wc -l &lt; junk.txt`
[root@***** ~]# (( LINECOUNT-- ))
[root@***** ~]# tail -${LINECOUNT} junk.txt
