You have a parent process that each time you do a ps -ef and grep for your userid, you will see the same parent, but different children processes.

$ ps -ef|grep unixops
unixops 8075 8070 0 13:53:20 pts/11 0:00 grep unixops
unixops 8070 595 1 13:53:13 pts/11 0:00 -ksh
$ ps -ef|grep unixops
unixops 8077 8070 0 13:53:27 pts/11 0:00 grep unixops
unixops 8070 595 1 13:53:13 pts/11 0:00 -ksh

Note that each show pid 8070 (-ksh) but the "grep unixops" has different pids. After completing the requested work (searching for unixops), the child process died. This is normal.

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.
