SHELL PROMPT CONTROL

Shell prompts to identify 
system and logged in users.

The entries can be made in 
the /etc/profiles file that 
TELNET and interactive terminal 
logins use.

If your SHELL=/bin/sh  
#for example SOLARIS

   PS1="`hostname1{$LOGNAME} "

If your SHELL=/bin/bash   
# for example Linux

   PS1='\h:\w\$ '

If your SHELL=/bin/zsh

   PS1="%m"%~%# "

The details of environment 
variable assignments are usually
documented in the man pages for 
the shell being used.

You may wish to test the 
substitutions by spawning a 
subshell (issuing the sh, bash, 
zsh, ksh, ash or other shell 
command), then perform the 
environment variable substitution 
assignments and see what happens.  
When you are satisfied with the
results, then place appropriate 
entries in the /etc/profile or 
startup script for your favorite shell program.
