On Terminals

There's no point in denying this: I'm a heavy terminal user. To be specific, I prefer plain 'ol xterm.

I'm a bit more particular than that though - I prefer xterm, with GNU Screen inside of it, Solarized color palette, and with a GNU Bash shell - with my customized .screenrc, .Xresources, .bashrc, command prompt, and extended tab completion (amongst others).

And because I'm such a nice guy, I'm going to share my customizations for each of these with you. Most of these I've had kicking around for years, and many of which started from something I found online. Sadly, I can't cite their origins any longer...

~/.Xresources

This is the config file from which I load X Resources. It's customized to be Solarized. I load it with xrdb .Xdefaults from within ~/.xsession.

~/.screenrc

Yeah, I know, I should be running tmux instead, but whatever.

This configuration does a couple of nice things - but mainly it adds a nice statusbar to the bottom of each session showing handy stuff like the hostname, the open pseudo-terminals, and the date and time.

startup_message off
caption string "%?%F%{= Bk}%? %C%A %D %d-%m-%Y %{= kB} %t%= %?%F%{= Bk}%:%{= wk}%? %n "

~/.bashrc

This is host I customize my shell on most systems. I sometimes have to do a bit of work for this to work like symlinking .bash_profile to it or pointing it at a custom location for the bash completion stuff - but this generally gets me where I want to be.

~/.vimrc

I'm not terribly fancy with how I configure vim. I don't bother with the solarized theme for vim because I found that having the X resources configured already gives me what I want.

set softtabstop=4
set shiftwidth=4

"set textwidth=80
set expandtab
set modeline modelines=5

~/.ssh/config

This isn't my entire ssh config file, but these are the common elements that I always want by default. This makes the .ssh/known_hosts readable so you can find old entries and remove them easier, and it sets the TCP keepalive interval for SSH sessions which makes it play nicer with firewalls and NAT.

Host *
        ServerAliveInterval 60
        HashKnownHosts no

~/.kermrc

I tend to use Kermit for quick connections to serial devices, and this saves me a bit of time usually.

set speed 115200
set carrier-watch off
set flow-control none
