Full Discussion: capturing the output of grep as integer variable
Top Forums UNIX for Dummies Questions & Answers capturing the output of grep as integer variable Post 10560 by Rado1x on Friday 16th of November 2001 09:05:34 AM

Use :
counter=`ps -ef|grep $project | grep -v grep | nawk '{print $2}'`

It may be difficult to seen, but your pine is inserted in to ` ` - this is not quote; this character is left from "1" on the keyboard.

You can use counter=$( ... your pipe ..)

Syntax is depending on the shell. See "command substitution" section in the man page.

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)
