Making Directories

I have a simple question;

Let's assume I'm somewhere other than the home directory using the command line, for example, I've navigated to /home/documents/exam/revision

Is there anyway, from the current location, to create a new directory or file into any the preceding directories, for example, creating a directory called pipes in the home directory.

Or can you only do so by changing to the directory and issuing the mkdir command?

Thanks in advance!

you can use relative (from where you are) or absolute (the fully qualified name) path from anywhere on the system.
~/ indicates your home directory, so if your username was jpaul and your home directory was /home/jpaul, then would create /home/jpaul/new_dir from anywhere in teh system.
../ refers to the directory directly above the one you are at. So if you are in /usr/bin/someplace and you do then you will have created the directory /usr/share/new_dir
./ refers to the current working directory and is usually not of much use in typing in path names.

Realize that you must have permissions to create these directories or they will not be created. Also, to make things easier, you can set up an environment variable to represent a commonly used path. Say, for example you always put files in a location /home/jpaul/backups/current/ but you copy files there from all over the system, then you can create an environment variable called BKUP (in bash you would do export BKUP=/home/jpaul/backups/current/ or edit your .bashrc) then you could (from anywhere) do

Thanks alot!

So... if i was in home/dtaylor/dir1/dir2/dir3

And i wished to create a directory called subdir1 in dir1, I could do the following:

mkdir ~/dtaylor/dir1/subdir1

or

mkdir ../../subdir1 ?

I know I should be testing this for myself, but I don't have Linux at home for the time being.

Should be

Other than that, yes.
