How are the indented lines added several of the cells like Screen Shortcuts? RE: http://getsatisfaction.com/cheatography/topics/adding_a_two_line_entry_in_a_list
Ah, Q&A means I would be able to cheat with it and use it for two column with an extra line. Thanks for the info.
(Replying to my original post seems unintuitive for trying to reply under your post, but not to the overall thread... assuming this post as I'm thinking it might.)
I think the "Bash Shortcuts" part is a little misleading. The "ctrl-a", "ctrl-e", "ctrl-k" is in emacs mode. But there should be many people preferring vim-mode or some thing like that.
Love your work....it is so ....so helpful! I would like to format a MicroDisk using Linux Centros. When I look at the Partition on the MicroDisk, I see the following comment....(non-Linux). This makes sense, since I formatted with a computer running Win 7! I want to use it on my Linux system but do not know how to do it. I tried format /dev/scd1 but no joy!
Thank you
Don
I'd just like to point out a trick I use with the head and tail commands:
First, you can designate the number of lines to return, like so: head -100 filename
I often use both head and tail together to get a section of a file by piping the output of one into the other. The following command gets 100 lines, starting 1000 lines before the end of the file:
tail -1000 filename | head -100
You could, of course, reverse the commands to get a section near the top of the file. To get lines 91-100:
head -100 filename | tail -10
I just wanted to take a moment to thank you for putting this together. This is a big help to me I am new to OpenFiler witch I believe uses bash at the core so I am of course new to Linux. I didn't really think it would be quite so difficult to find resources that one can use to navigate the command line but I guess most folks use the GUI. But, I'm not most folks when I bought my first IBM 8088 I started with DOS.Anyway, thanks for the time and effort you put into this, sorry about digressing there.
However, I don't like the "chmod" commands you are using. I don't think anybody should use the numeric version of chmod anymore. Your example "chmod -R 600 folder", is the best way to lock yourself out of your own folder and loose any executable bits on the scripts. I would rather use the symbolic version:
chmod -R u+rw folder # Add read-write for user on all files in folder
chmod -R og-rwx # Remove read write and execute bits for "other" and "group" on all files in folder
And my all-time favorite:
chmod -R og=u-w folder # Give other and group the same rights as user, but removing writing rights.
Great resource - thanks for taking the time and trouble to put this out there.
My favorite ls options are '-ltr' . The t sorts files by time, and r reverses that, so newest files show up right above the prompt, no matter how long the listing is.

Thanks for creating this cheat-sheet Dave. The one thing I missed was "grep -o"; Show only the part of a matching line that matches PATTERN
I've added "grep -o" to the cheat sheet :)
The I/O redirection section could use "2>" and "&>" examples, I always forget how to redirect stderr
Good idea - I'll add that (once I remember how they work myself ... :) )
I've updated that section to include stderr redirection. :)

Those indented bits are a "question and answer" format box.

On the redirects, the one I most commonly use is ignoring errors (2>/dev/null, or more succinctly 2>&- ).
For example, if I'm looking for files and I don't care that I haven't access to parts of the filesystem, we might do something like:
find / -name "*.html" 2>&-
ls -h is handy - changes sizes to human readable formats. Goes along good with -S. If I'm using it it is generally a ls -alhS
I think the "Bash Shortcuts" part is a little misleading. The "ctrl-a", "ctrl-e", "ctrl-k" is in emacs mode. But there should be many people preferring vim-mode or some thing like that.
Thanks a lot for your sheet, I just need such a linux command summary such as this sheet.
Awesome job! This will definitely come in handy
download PDF is broken
Good work. Thanks, its helpful.
Hi,
Fantastic good job..
Thanks

Excellent Stuff man.. I think these are the most commonly used commands.. Good Effort.
you need to figure out how to split your command sheet as a pdf
hi!.these are useful cheat sheet .
CTRL-Z sleeps (stops) the running process. fg [#] brings it back to foreground.
top
CTRL-Z
ps aux | grep top
fg
Show human readable format (kb, mb...)
ls -lh
This cheat-sheet is very good! Thanks for that.

Your example "chmod -R 600 folder", is the best way to lock yourself out of your own folder and loose any executable bits on the scripts. I would rather use the symbolic version:

And my all-time favorite:
chmod -R og=u-w folder # Give other and group the same rights as user, but removing writing rights.
Of course, this also handles t and s bits:
chmod u+s file
chmod o+t folder
I would also add the tar command. No sysadmin would survive without it.
To extract tar.gz archive
tar xvzf archive.tar.gz
To extract tar.bz2 archive
tar xvjf archive.tar.bz2
To extract tar archive
tar xvf archive.tar
To create archive
tar cvzf archive.tar.gz /file_or_folder/to/archive
Nice one...really helpful
Great resource - thanks for taking the time and trouble to put this out there.

What about CTRL+y to paste the stuff you cut back in? How can you leave that out? CTRL+a/e and CTRL+u/y are the pairs I remember.
Missing: sed
find -exec
Nice work, but it would be best as a single page PDF.
Or if the PDF at least split into 2 pages (so it could be a laminated 2-sided sheet) without cutting commands in half.
