A while back I wrote a post of BASH or SSH Commands. In this post I add several other useful Linux commands.
BASH Commands
ls -alh – list directory
history – lists a history of commands run
cat – Display file on screen
grep – keyword search
less – read a file and format for pages
host – displays server name
clear – clears the terminal screen
exit – exits terminal log in
kill – kills processes
rm – remove file
cp – copy a file
mv – move a file
vi – advanced text editor
nano – text editor
strings – Interprets Binary files and shows what can be printed on the screen
cd – change working directory
pwd – print working directory
tail – displays the last 10 lines of the file unless -n is used to tell it how many lines to go up -c is how many bytes you want. -f to follow the log.
touch – creates an empty text file and updates the modified
date – outputs the current date of the system
which – gives full binary path to commands
Vi and Vim Commands
In the Linux community there seems to be no conflict greater than the Emacs vs vi/vim editor, with others, like Pico/Nano/Joe with vocal minorities. I started with Pico as my first editor. I have since used many systems, and I find vi or vim most likely installed by default.
Vim has many commands. Whole books cover it. Here are some basic commands to get you started.
dd – Delete Line. You can also type a number and dd to delete multiple lines.
wq – Save and quit.
q! – Quit without saving.
set nu – Show line numbers.
i – Insert text.
