Optimize images with cronjob

With image styles and responsive breakpoints drupal generates automatically smaller images from the original uploaded ones.

Find lines in big files

Get all lines in a big file containing some text:

cat filename  | egrep "|||"

Thanks to Günter!

Find files NOT of type

find . -type f -not -iname "*.jpg" -not -iname "*.jpeg" -not -iname "*.gif" -not -iname "*.png" -not -iname "*.pdf"


Split files on lines

Split the file into multiple files at every 3rd line . i.e, First 3 lines into F1, next 3 lines into F2 and so on:

$ awk 'NR%3==1{x="F"++i;}{print > x}' filename

SCP syntax

Useful to copy directories from one server to another:

cd into the dir you want to have your data

scp -prq username@ .
