how to exclude the GREP command from GREP
I am doing "ps -f" to see my process.
but I get lines that one of it represents the ps command itself.
I want to grep it out using -v flag, but than I get another process that belongs to the GREP itself :
I would like to exclude
[root@localhost ~]# ps -f
UID PID PPID C STIME TTY TIME CMD
root 15794 15792 0 13:48 pts/2 00:00:00 -bash
root 16157 15794 0 14:01 pts/2 00:00:00 ps -f
[root@localhost ~]# ps -f | grep -v ps
UID PID PPID C STIME TTY TIME CMD
root 15794 15792 0 13:48 pts/2 00:00:00 -bash
root 16160 15794 0 14:02 pts/2 00:00:00 -bash
while all I want is to get my pid line only.
or maybe you know another command that returns my pid and ppid only ?
thanks

GZGREP(1) General Commands Manual GZGREP(1)
NAME
gzgrep, gzegrep, gzfgrep - search possibly compressed files for a regular expression
SYNOPSIS
gzgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
gzgrep is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep. If no file is speci-
fied, 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 gzgrep is invoked as gzegrep or gzfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, gzgrep
uses it as the grep program to be invoked. For example:
for sh: GREP=fgrep gzgrep string files
for csh: (setenv GREP fgrep; gzgrep string files)
