    Question How To Combine Commands in Linux

    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'.
    You think that's air you're breathing now?

    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.

    Another well written man page is the 'find' page, pity they are all not as well done .
