The linux terminal is your lifeblood. There are so many - TOO MANY - options. I'll gather a few of my favorite things here.

Host-specific color and banner

This is mucho importante to quickly tell which machine you are on:

  • use figlet and jp2a to create ascii art
  • update ~/.bashrc to echo the ascii art in a host-specific color, and to persist that color in the prompt
  • make sure to include an interactive check to avoid the banner if not interactive

See the many examples of .bashrc in the config repo.

Keyboard-driven copy-paste

HOW DID I LIVE SO LONG WITHOUT THIS! You can do keyboard-driven copy-paste from terminal buffer using screen!

  • Ctrl-A-esc to get into buffer navigation mode
  • space to mark the start of the copy buffer (non-column)
  • space to mark the end of the copy buffer
  • then you can use Ctrl-A-] to paste - wait, wut? useless... what about X buffer?
    • add this to "your screen .rc file" to send buffer to X clipboard too!
bindkey -m ' ' eval 'stuff \040' 'writebuf' 'exec sh -c "/usr/bin/pbcopy < /tmp/screen-exchange"'

Always use screen when ssh'ing

Best to accomplish this with a script. This will also allow us to provide host-specific background graphics and profile colors, sweeeeet!

   mah-haus-provided ssh commands!
       mh bitpost {screenname}
           save term background/profile
           change term background/profile - with host pic in upper right!!
           use this script to ssh bitpost:
               https://stackoverflow.com/a/1075956/717274
               also:
                   On my Ubuntu system (10.4) I had to modify the regular expression to account for the date/time info it prints next to each session.
                   if(/^\s*(\d+)\.(\S+)\s+(([^)]*))\s+(([^)‌​]*))/) { ($num, $tag, $status) = ($1, $2, $4); –
               or:
                   ssh -t user@some.domain.com /usr/bin/screen -xRR
                   -t is needed to force terminal creation (even tho sending a command)
                   -x
                   -R restore existing or create if none
                   # see MY screen settings with at to see what i really want

               better to let screen do the ssh?
                  screen -S 1-9 -p 0 -X screen -t Remote ssh 19

           reset term background/profile

session-specific screen "create if needed or connect if exists"

#!/bin/bash
# -R will simply reattach if found, otherwise run as if a new request.  PERFECT
screen -d -R -S #sessionname# 'export PS1="$PS1[sn] "; /bin/bash'

Drop a dead ssh session

Remember this one to drop a dead ssh session!
