Need help with grep command
Hi guys, i wondering with any1 could help me with this.
I have this script will i need to "grep" an integer form a file x2. If the value is 0 then it's ok. But anything greater then 0, i'll ask the script to echo an error message. This is how the script looks like:
Code:
MESSAGEFILE=x2
STRING="0"

if  grep "$STRING"  /tmp/$MESSAGEFILE > /dev/null
 then
  echo " data is running smoothly"
  exit 0
fi
echo " - Data is pilling up"
exit 2

the problem i'm having now is how do i grep an integer and check whether if it's greater then or equals to 0?
Any advice would be greatly appreciated.

zegrep

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME

     zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files

SYNOPSIS

     zgrep [grep-flags] [--] pattern [files ...]

     zegrep [grep-flags] [--] pattern [file ...]

     zfgrep [grep-flags] [--] pattern [file ...]

DESCRIPTION

     zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1).

     The grep-flags and pattern arguments are passed on to grep(1).  If an -e flag is found in the grep-flags, zgrep will not look for a pattern
     argument.

     zegrep calls egrep(1), while zfgrep calls fgrep(1).

EXIT STATUS

     In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.

SEE ALSO

     egrep(1), fgrep(1), grep(1), gzip(1), zcat(1)
