How To Combine Commands in Linux

**vokevybez** · July 5th, 2012

How do i combine commands like for example if i wanted to combine

Code:

cd /home

and

Code:

cd /media

consecutively. Is there a specific symbol or something of the sort?

There is a syntax to
a) Run commands one after the other (only if the command before it is successful)
b) Run commands all at once.

a) uses "&&"

For example,

Code:

cd /root && touch test && touch test2

That would run one command after the other

b) uses "&"

For example

Code:

cd /root & touch test & touch test2

That would run all of them at once, and would probably not be advisable.

c) Run the commands sequentially, regardless if the previous command in the chain was successful or not: use the semicolon.

Code:

cd /home ; ls -l ; cd /root ; ls -l

Most of the information has been presented here for you but the gruesome details can be seen in the bash man pages under 'Lists'.

Real men read the man pages because they like learning about all those gruesome details! I'll admit the bash man page is a bit overwhelming though. The "grep" man page isn't far behind.
