.profile and the ENV file

Here are the steps involved in changing the startup files for the user:

you may need to change the contents of the .dtprofile in your home directory and make sure that the following line is uncommented (no leading #)
```
   DTSOURCEFILE=true
```
add these lines at the VERY END of the .profile
```
   ENV=$HOME/.shrc
   export ENV
```
create the ENV file in your home directory
```
   $ cd
   $ touch .shrc
```

here are the contents of the $HOME/.shrc file

   EDITOR=vi
   # PRINTER=HP5L
   # TERM=vt100
   HISTFILE=$HOME/.sh_history
   HISTSIZE=128

   set -o vi
   set -o noclobber

   export PS1="$LOGNAME@$(hostname)>$(echo '$PWD')$"
   export PS2='cont>'

   alias ll='ls -l '
   alias dir='ls -l'
