YIOOOOOOOOOOOOOOOOO

1. Initialize empty repo at $HOME dir

git init --bare $HOME/.dotfiles

2. Use working directory of git as $HOME, and git dir as .dotfiles

alias config='/usr/bin/git --git-dir=$HOME/.dotfiles/ --work-tree=$HOME'

3. Set git to ignore untracked files, Only for current local repo, because it’s annoying.

config config status.showUntrackedFiles no

4. Here you go, check status, add your configs, commit and push

config status
config add .config/mpv
config commit -m "Added mpv config"
config remote add origin <link>
config push origin master

1. Forward port server port (80) to localhost (8111).

ssh -L 8111:localhost:80 user@server
curl "http://localhost:8111" # on host

Your server:80 is mapped to localhost:8111. Now in your host system you can access your server’s local service. [host]8111—<—-[ssh]—<–80[server]

2. Forward localhost port (5000) to server port (8011).

ssh -R 8011:localhost:5000 user@server
curl "http://localhost:8011" # on server

Your localhost:5000 is mapped to server:8011. Now in server you can access your host systems local service. [host]5000—->—[ssh]—>—8011[server]

1. Kill process on port 80

kill -9 $(lsof -t -i:80)

2. Another method:

fuser -k 80/tcp

1. Copy your files to ~/.ssh.

cp /path/to/my/key/id_rsa ~/.ssh/id_rsa
cp /path/to/my/key/id_rsa.pub ~/.ssh/id_rsa.pub

2. Change permissions of files

sudo chmod 600 ~/.ssh/id_rsa
sudo chmod 644 ~/.ssh/id_rsa.pub

3. Start the ssh-agent in the background and add the key to agent

eval $(ssh-agent -s)
ssh-add ~/.ssh/id_rsa

NOTE: If using fish shell,then just execute the ssh-agent -s and then export those printed vars. No need to import public key.

UseCase: After updating a group, you want to take effect of it without logging out.

1. Use newgrp command followed by group name you updated

newgrp <group>

2. Now check if changes were made.

id $USER
