while loop is all I need now
Hi all,
now all I need is to make my while loop to work, which might be syntax.

So I have

i=1
while[-n `diskutil list | grep disk1s"$i"s2 | awk '{print$3}' ]; do
echo `diskutil list | grep disk1s"$i"s2 | awk '{print$3 " " $4}'
i+=1
done

If I remove the while loop portion just keeping the i= and the echo line it works perfectly, If I make the i=2 and so forth it works perfectly, so I know that my while loop is not correct.

Thanks,
Steven Stuart

zgrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
