Chapter 3: Hints and Tips

When using e-script in a real-life situation, the following hints may prove useful:

Remember that remote execution via inetd doesn't provide a full working environment (in contrast to a login shell). This can be circumvented by sourcing /etc/profile before any other commands, as in:
```
unpack-and-build-prog	. /etc/profile; \ 
			cd /home/user/src; \ 
			tar xzf $(SRC); \ 
			cd prog; \ 
			make; \ 
			make install
```
The effective user to execute Unix commands is defined in /etc/inetd.conf. (In the example of section 2, this is root). An effective way of allowing a multiple-user setup is to let root run e-script, but to su to a different user depending on each pseudo-command. An example is given below:
```
# This should run as user "sample"	
unpack-and-build-prog	su - sample -c ' \ 
			    . /etc/profile; \ 
			    cd /home/user/src; \ 
			    tar xzf $(SRC); \ 
			    cd prog; \ 
			    make; \ 
 			    make install'
```
A different pseudo-command might obviously su to a different user.
