Below is the collection of Linux command line tips which I’ve found useful for Linux users. To get more information about the command mentioned below just open your terminal and type man <command>.

Suppose you have a long-running task (for example, compiling a large program) that you need to run, but you also want to get some other work done. Linux lets you start a task in the background and keep on doing other things from the command prompt.

We will see in this article how to send commands in the background, then return them to the foreground, and make sure that also closing the current shell or terminal the process doesn’t remains tied to the session but continue to work.

An alternative to these command is using screen, as read in a former article, but now let’s seethe command bg and the spacial character &

SSH has many features which are helpful when working regularly with files on remote servers; together they can give a vast increase in productivity over the bare use of SSH. If you regularly use SSH, it’s worth spending a little time learning about these and configuring your environment to make your life easier.

SCP
The scp command allows you to copy files over ssh connections. This is pretty useful if you want to transport files between computers, for example to backup something. The scp command uses the ssh command and they are very much alike. However, there are some important differences.

The scp command can be used in three* ways: to copy from a (remote) server to your computer, to copy from your computer to a (remote) server, and to copy from a (remote) server to another (remote) server. In the third case, the data is transferred directly between the servers; your own computer will only tell the servers what to do.

find will find files recursively in sub directories, if any. If that's what you want, great. If you only want files in the current directory, you can use:

for i in *.tar.gz; do tar xzvf $i; done

Here’s a simple but nifty trick. Say you’re navigating around in the Terminal and you would like to see the present working directory in the Finder? Just type

% open .
and the Finder will open up the folder you’re in. This works in both xterms and the Apple Terminal.
