# Usage:
#
#   pash hostname
#   myself@hostname:~$ sudo ls 
#   [sudo] password for myself: CTRL+SHIFT+V
#
# In other words, it copies your password in your clipboard and does 'ssh hostname'.
# Then, you can quickly paste your password when needed.
#
# The command 'copypass hostname' just copies your password in the clipboard.
#
# Installation
#
# 1. install xclip: sudo apt install xclip
#
# 2. Create a directory where, for each of your remote server, you create a file with your password.
#    Be sure to have your harddisk encrypted, or use an encrypted directory.
#    Also, do a chmod 700 of the directory.
#    Example: say your remote servers are nas-router, core.pippo.org, dev.topolino.org, ...
#       mkdir ~/.passwords
#       chmod 700 ~/.passwords
#       echo "a secret password" > ~/.passwords/nas-router
#       echo "my secret password" > ~/.passwords/core.pippo.org
#       echo "another secret password" > ~/.passwords/dev.topolino.org
#
# 3. Put this code in your ~/.config/fish/config.fish
#    
# Notes: to change the location of the directory ~/.passwords, configure PASSWORD_DIR.
#

set PASSWORD_DIR ~/.passwords
