Processes

• Sometimes a command or program you run in the terminal goes on too long, or is obviously doing something

you did not plan.

• If there is no obvious way (such as a menu option or button) to stop the program running, try using Ctrl-c
• A command can include the output of another command by generating a process via the `` or $() operators.

Questions

• Try these three commands:

ls
echo `ls`
echo $(ls)

• The results are the same but the method is different. Does it matter?
