CLI cheat sheet

Postby carlos on Fri Aug 03, 2007 10:02 am

Just found this great little cheat sheet for CLI commands.

Download it, print it and keep it local. Its great for beginners (like myself) who have a hard time remember all of the commands :D

...or use the arrow keys - up and down...
Tab comes in handy as well for filling out...

Then you can !+number to repeat a history command, e.g. if history displays
Code: Select all
169  sleep 40m; cd /datastorage/user1/enc/JDownloader ; java -jar /datastorage/user1/enc/JDownloader/JDownloader.jar

just type !169 to do it again. No need for arrow scrolling or retyping.

When looking for some command you partially remember, use
Code: Select all
 history | grep keyword
to only display this, e.g.
Code: Select all
history | grep JDownloader
will find the above command.

Great resource thread! Thank you for putting this together. I've been lurking in the forums since making the switch from W8 to Linux, and I've been looking for something like this. I've been creating my own CLI lists as I go, but they're mainly geared towards building Android...Outside of those commands and a few very basic ones, I always needed to search for commands, prior to executing them. This will provide me with a very handy quick reference guide, so I can begin to commit some of these commands to memory. :)

Here are some of my faveorite commands that I use regularly. Look them up if you need help with them by doing man <command>. Replace all instances of <command> or <2nd_command> with an actual command that you want to use. Ignore anything after a // as thats a comment!

ls -aR //list all files recursively
less //lets you scroll through large outputs
cat //list entire file. Useful when piped into other commands
grep //search for stuff within files or output
whereis //find stuff
find //find more stuff
locate //Guess what? Also lets you find stuff.
which //And who would have thought! Find more stuff!
pushd //push directory
popd //pop directory
cd //change directory
mkdir //make directory
rmdir //remove directory
<command> | <2nd_command> //piping commands into eachother
<command> > file.txt //outputs to a file.
man //get help
top //lists processes and resources usage
kill //kill a frozen or resource hogging proccess

And a few others like netstat and blkid and such that have there uses, but not used regularly. Why do I use top regularly? I'm a n00b programmer, and sometimes my programs get memory leaks so I use top to find the offending proccess and then kill it. Why do I also use 5 different commands to search for stuff? Each command searches for different things in different ways. All 5 have their uses. Though grep is probably most useful. And yes, I do (mostly) read man pages when I get stuck.

I may post more useful commands in the future. There are a LOT of them.

Happy command line adventures,
