Pen

Setup

# Clone the repo
# I recommend you to clone it in /opt directory
git clone https://github.com/uwumouse/pen

# Setup penta.
# It'll create a script in your .bashrc to update env variables in all of your terminals
# And will create a global command 'pen'
chmod +x ./setup.sh
./setup.sh

Usage

Pen allows to export a text-value to ENV variable $PEN that is accessible in any terminal. It is because in your .bashrc is a trap command that catches every command in any terminal and updates value with a value in ~/.pen file.

So Pen ships with 2 commands:

export (e)

# Will store "value" in ~/.pen and export it to $PEN variable in shell
$ pen export value
# Alias
$ pen e value

show (s)

$ pen show # Shows a value from ~/.pen file
$ pen show -c # Shows a value and copies it to clipboard via xclip
# Alias
$ pen s

Where it can be used?

The idea of this program came to me because when I do CTFs I need the IP of the box quite often.
So I need to constantly copy it from the site if I need to do payload or something different.
It would be easier for me if I could access this variable with a variable in terminal.
But writing export $IP=<machine-ip> everytime I open a new window is kind of annoying, so Pen makes life easier by allowing to use variable I set from any terminal.
