Files

File Operations

ls # list all files
ls -la # all files, plus perms

cat ./file.txt # print to console
./script.sh # run a script

Interactive editors

If you are just stating, use nano for simplicity. To exit, hit CTRL + X and hit "y" or "n" when asked about changes.

nano file.txt # open interactive editor
sudo nano file.txt # edit as root

Deletions

# NOT RECURSIVE
rm file.txt
rm * # WIPES OUT ALL FILES IN DIRECTORY

# RECURSIVE WITH SUB-FOLDERS
sudo rm -rf ./folder # NUKE IT, THERE'S NO GOING BACK

Path traversal

pwd # get current path to folder
realpath file.txt # get current path including filename

cd / # go to the root
cd ../ # go back one folder
cd ~ # user root user directory like /Users/USERNAME

cd Desktop/ # traverse into a folder
cd folder/another/another # go multiple levels deep in one command
# pressing tab will allow for autocomplete

Seaching for files

By using the pipe operator, we can have grep filter everything out not including "tacos"

ls | grep "tacos"

Find

Search through everything

find / -type d -name "folder"
