Experimentation:

Code:
$ ps ax | grep rv_
 3382 pts/1    T      0:00 /bin/sh ./rv_server
 3414 pts/1    T      0:00 /bin/sh ./rv_test
 3443 pts/1    T      0:00 /bin/sh ./rv_test
 3450 pts/1    S+     0:00 grep -i rv_
$ pkill -9 rv_
$ ps ax | grep rv_
 3453 pts/1    S+     0:00 grep -i rv_
[3]   Killed                  ./rv_server
[4]-  Killed                  ./rv_test
[5]+  Killed                  ./rv_test
$ ps ax | grep rv_
 3455 pts/1    S+     0:00 grep -i rv_

Perfectly agree, I missed it. Operand is a pattern and not a literal. Thanks

zfgrep

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)
