Share your commandline cheat sheets

[billgoldberg]

Ok, I have been needing to do this for a long time.

I need a cheat sheet of commands.

I know there are some on the web, but they are mostly basic lists.

Do you have a list with useful commands?

Share them.

(I'll be happy to rip them)

ps: I have a basic one here:

It seems kind of redundant to open a root shell with sudo. I guess it's because Ubuntu doesn't set a root password by default.

Here are some handy basic commands to know:

cat - print contents of a file
cd - change directories
chmod - change file permissions
cp - copy a file
grep - searches for a given string
ln - link files
ls - list the files in the current directory
mkdir - make directory
more - helps page through output ( cat file.txt | more)
mv - move a file
rm - delete files and directories
top - shows resource usage

Helpful symbols:
| - pipe the output of one command into the next
& - detach process from shell (run in background)
&& - chain two or more commands together (if the first is successful)

Fosswire has a couple good printable sheets.

These 4 commands are useful:




-- CHANGE folder of .svg's to .png's and resize all the images:

for i in *.svg; do inkscape -f "$i" -e "$i.png" -w24 -h24; done

-- CHANGE one .svg to a .png and resize the image:

inkscape *.svg --export-png=*.png -w24 -h24

-- check hard drive temp:

hddtemp /dev/sda

-- GDM screenshot:

chvt 7 ; sleep 5 ; XAUTHORITY=/var/lib/gdm/:0.Xauth DISPLAY=:0.0 import -window root /tmp/gdm-shot.png

One I use a lot is:

ls -ltr
ls -a -ltr

For seeing what is actually in a directory

~$cat .bashrc | grep "alias"
# ~/.bash_aliases, instead of adding them here directly.

I believe that says it all (literally!)

Interesting.

I might start doing this when intrepid comes out.

Aliases are quite handy, especially ones for apt and tar, as the most command things I do are rather verbose.
