Shell scripts - great way to automate repeating tasks

Once you know shell commands, there's no scripting language to learn

Shell Scripts

• Automate steps with a shell script

> cat > hwcgi.sh
#!/bin/sh
c89 -c helloworld.c
ar -rv libhw.a helloworld.o
c89 -c hwcgimain.c
c89 -o hwcgi hwcgimain.o -L. -lhw      

• Execute permission required to execute

> chmod u+x hwcgi.sh
> hwcgi.sh      

• Special scripts: /etc/profile and .profile
