Useful commands to daily drive Linux

Not gonna lie but people(including me) forget basic commands more than they admit! so here are few commands that someone definitely needs to know and remember🤓.

cd is used to change directory.

cd .. brings you back one directory cd ~ brings you to home directory

File Handling

touch is used to create files

• rm <file_name>

Viewing Files

use this to read text files and scroll through pages
