How to add to PATH variable

The name of the PATH variable is case-sensitive and must be all-uppercase.

export PATH=$PATH:/folder/you/want

To verify your change, run:

echo $PATH

id -Gn [user]

find files with a specific name in a directory

find /opt -name httpd.conf

pmset -g assertions

see scheduled tasks

launchctl list | grep com.local.sendrequest

close specific task

pkill -f "ng serve"

close task at port

lsof -ti:3514 | xargs kill -9 2>/dev/null || echo "No processes on port 3514"

connect to ssh server

if you have an authorised .ssh key in the ~/.ssh folder, you can do

ssh {{user}}@{{ip-or-domain}}

restart ssh server

if you have modified config or something, you can do

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