one way, using similar to what you have, and different FS for purposes of example:

Code:
#  df -h /tmp
Filesystem             size   used  avail capacity  Mounted on
swap                    78G   670M    77G     1%    /tmp

so,


#  df -h /tmp |awk 'NR==2{print substr($4,1,length($4)-1)}'
77

using grep has potential to hit multiple matches, so df the FS directly...

This is nice.... caveat - works for nawk, but not (solaris) awk

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.
