the command "ps -ef | grep -v grep | grep listen" gives (all bar
command line delted)

/usr/etc/tcplisten ftp finger rlogin remsh rexec telnet 
listen -n tcp -l 0002040190570101 

while "ps -ef | grep listen" gives (all bar command line delted)

/usr/etc/tcplisten ftp finger rlogin remsh rexec telnet 
listen -n tcp -l 0002040190570101 
sh -c ps -ef | grep listen 
grep listen 

now obviously the shell to run the grep (*) and the grep itself have
now died so if you are wanting just the running commands or something
similar you need to remove the greps. In otherwords sometimes you need
it.
