UNIX Command Line: Basics

trinadin — Fri, 17 Jun 2011 04:40:21 +0000

Meant as a quick reference of basic commands for people who are new to using UNIX shell.

Click on any of the links below to quickly jump to that section of the page.
You may also hover your mouse over each link to see the full title of that section.

Directory Examples:

File and directory paths in UNIX use the forward slash "/" to separate directory names.

/	"root" directory
/usr	directory usr (sub-directory of / "root" directory)
/usr/SUBDIR	SUBDIR is a subdirectory of /usr

Navigating the File System:

pwd	Display the "present working directory", or current directory.
cd	Change current directory to your HOME directory.
cd /usr/SUBDIR	Change current directory to your HOME directory.
cd INIT	Change current directory to INIT which is a sub-directory of the current directory.
cd ..	Change current directory to the parent directory of the current directory.
cd $THISVARIES	Change current directory to the one defined by the environment variable 'THISVARIES'.
cd ~trin	Change the current directory to the user trin's home directory (if you have permission).

Listing Directory Contents:

ls	List a directory.
ls -l	List a directory in long (detailed) format.
ls -a	List the current directory including hidden files. Hidden files start with "."
ls -ld *	List all the file and directory names in the current directory using long format. Without the "d" option, ls would list the contents of any sub-directory of the current. With the "d" option, ls just lists them like regular files.

Changing File Permissions and Attributes:

You must be the owner of the file/directory or be root before you can do any of these things.

chmod 755 file	Changes the permissions of file to be rwx for the owner, and rx for the group and the world. (7 = rwx = 111 binary. 5 = r-x = 101 binary)
chgrp user file	Makes file belong to the group user.
chown trin file	Makes trin the owner of file.
chown -R cliff dir	Makes cliff the owner of dir and everything in its directory tree.

Moving, Renaming, and Copying Files:

cp file1 file2	Copy a file.
mv file1 newname	Move or rename a file.
mv file1 ~/SUBDIR/	Move file1 into sub-directory SUBDIR in your home directory.
rm file1 [file2 ...]	Remove or delete a file.
rm -r dir1 [dir2...]	Recursivly remove a directory and its contents. BE CAREFUL!
mkdir dir1 [dir2...]	Create directories.
mkdir -p dirpath	Create the directory dirpath, including all implied directories in the path.
rmdir dir1 [dir2...]	Remove an empty directory.

Viewing and Editing Files:

cat filename	Dump a file to the screen in ASCII.
more filename	Progressively dump a file to the screen: ENTER = One Line Down / SPACEBAR = Page Down / Q = Quit
less filename	Like more, but you can use Page-Up too. Not on all systems.
vi filename	Edit a file using the VI editor. All UNIX systems will have VI in some form.
emacs filename	Edit a file using the Emacs editor. Not all systems will have Emacs.
nano filename	Edit a file using the Nano editor. Not all systems will have Nano.
head filename	Show the first few lines of a file.
head -n filename	Show the first n lines of a file.
tail filename	Show the last few lines of a file.
tail -n filename	Show the last n lines of a file.

Where’s Chuck D. When Ya Need Him?

trinadin — Wed, 01 Jun 2011 14:24:25 +0000

I'm back. I'm finally back. Are you happy to see me? I'm happy to see me.

Note to self: Do not rely on the hosting accounts of others. Your shit will be lost eventually.

So, I'll be completely rebuilding this site. Sort of, at least. I'm going to use the same theme as last time. I'll still have to tweak it quite a bit but whatever, no biggie. It's always good to brush up on my WordPress skills anyways since it's apparently TAKING OVER THE FUCKING WORLD.

But... but... what will I post? Do I have anything worth saying? Am I even that interesting?

Fuck ya I am. To me at least. I mean, do "you people" even have the slightest idea how many rants flow through my head on a daily basis? Like, at least 2, in a row, at a time. Hell, I've even gone as far as to create a category dedicated specifically to these rants, which is appropriately titled "Rants" and falls appropriately under "Relapses."

Now, if you've already looked, then you've no doubt seen that it hasn't been populated with anything yet. This is due largely to the fact that, well, let's face it, not every single one of my rants is "post worthy." Some of them most certainly are though, and as soon as I'm able to get them typed up, you best believe they'll be making their way up here with a quickness.

To wrap things up, please explain in one word or less what you've learned here so far...

Nothing?! PERFECT! You picked up exactly what I put down. Mission accomplished on my part.

Anyways, stay tuned folks, there's more mediocrity on the way than you can shake a stick at!
