Commands I Use Frequently (Vim, Bash, more)
VIM:
Numerate numerable element in visual selection:
visual select - g - ctrl+a
example:
Visual block:
ctrl-v - select - shift+I - write - esc
example: say we want to append ![] to the beginning of multiple lines.
(/serv1.png)
(/serv1.png)
(/serv1.png)
(/serv1.png)
(/serv1.png)
(/serv1.png)
(/serv1.png)
It can be done simply with the above command.
Copy and paste from vim
"*y "*p
to “yank” text into the * register then to paste …or
"+y then "+p
Capitalize first letter of each word in selected region
s/\<./\u&/g
\< matches the start of a word
. matches the first character of a word
\u tells Vim to uppercase the following character in the substitution string (&)
& means substitute whatever was matched on the left-hand side
g means substitute all matches, not only the first
BASH:
Find what directory a file is in.
example
find . -name "*.py" -type f
locate any file name ending in .py
find . -name "*.py" -type f -exec cat {} + > all.py
locate any file name ending in .py, then execute cat for each file into a new
file called all.py
Turn down brightness and soften screen (reduce bluelight)
example
xrandr --output VGA-1 --brightness .80 && redshift -O 2500
Concatinate multiple files into one:
cat *.html > output.html
Convert .docx to pdf
libreoffice --headless --convert-to pdf *.docx
New terminal opens in most recent working directory:
#save path on cd
function cd {
builtin cd $@
pwd > ~/.last_dir
}
#restore last saved path
if [ -f ~/.last_dir ]
then cd `cat ~/.last_dir`
fi
