==Prompt==
|
||||
|
||||
I originally built my prompt using http://bashrcgenerator.com and, while it's a nice tool for visually building a prompt, it has several limitations on what you're able to create with it. But more importantly to me, it generates a rediculously long string, defines and resets color for every single character, uses both a color and bold escape sequence to use light/bright colors, mixes raw escape sequences and subshells running tput, and as a result is utterly unreadable and unmaintainable.
|
||||
|
||||
So, I replaced it:
|
||||
|
||||
{{{class="prettyprint"
|
||||
### PROMPT ###
|
||||
|
||||
promptsetup() {
|
||||
# Color definitions for prompt
|
||||
local fg_brightred='\[$(tput setaf 9)\]'
|
||||
local fg_blue='\[$(tput setaf 4)\]'
|
||||
local fg_magenta='\[$(tput setaf 13)\]'
|
||||
local fg_cyan='\[$(tput setaf 6)\]'
|
||||
local fg_brightcyan='\[$(tput setaf 14)\]'
|
||||
local reset='\[$(tput sgr0)\]'
|
||||
|
||||
# [hh:mm][username@hostname pwd]$
|
||||
if [ -n "$SSH_CLIENT" ]; then
|
||||
# Remotely, hostname is red.
|
||||
PS1="${fg_blue}[\A]${fg_cyan}[${fg_brightcyan}\u${fg_cyan}@${fg_brightred}\h ${fg_cyan}\W]${reset}\$ "
|
||||
|
||||
elif [ -n "$VCSH_REPO_NAME" ]; then
|
||||
# If in a vcsh repo env, add repo name in magenta.
|
||||
PS1="${fg_blue}[\A]${fg_cyan}[${fg_brightcyan}\u${fg_cyan}@\h ${fg_magenta}$VCSH_REPO_NAME ${fg_cyan}\W]${reset}\$ "
|
||||
|
||||
else
|
||||
# Locally, hostname is cyan.
|
||||
PS1="${fg_blue}[\A]${fg_cyan}[${fg_brightcyan}\u${fg_cyan}@\h \W]${reset}\$ "
|
||||
fi
|
||||
}
|
||||
|
||||
promptsetup
|
||||
}}}
|
||||
|
||||
I intentionally put everything in a function and call it immediately so I may use local vars for the color definitions. I didn't really want to leave them around just in case.

==Profile==
|
||||
|
||||
Bash chooses which dotfile to source based on how it gets run. If starting from a login shell, `~/.bash_profile` will get sourced, but if there's not a command in there to source your `~/.bashrc`, you may find yourself having to `exec bash` after starting bash. This can be fixed by adding the following line to your `~/.bash_profile`:
|
||||
|
||||
{{{class="prettyprint"
|
||||
[[ -f ~/.bashrc ]] && . ~/.bashrc
|
||||
}}}
|
||||
|
||||
I also use `~/.bash_profile` for setting numlock while in a tty:
|
||||
|
||||
{{{class="prettyprint"
|
||||
case $(tty) in /dev/tty[0-9]*)
|
||||
setleds -D +num # (numlock for X is set in ~/.xinitrc)
|
||||
;;
|
||||
esac
|
||||
}}}
|
||||
|
||||
The last thing of note in my `~/.bash_profile` is a warning:
|
||||
|
||||
{{{class="prettyprint"
|
||||
# Temporary fix for a systemd bug related to systemd --user timers that run on login
|
||||
[[ -z "$DBUS_SESSION_BUS_ADDRESS" ]] && printf "%bWARNING: \$DBUS_SESSION_BUS_ADDRESS is unset! %b\n" "$(tput bold)$(tput setab 1)" "$(tput sgr0)"

==Get Dell Service Tag==
|
||||
|
||||
I work with Dell machines a lot, and when dealing with hardware problems, it's nice to have the service tag handy. Lucky for me, the service tag is easily retrieveable using `dmidecode(1)`, so I made a function for it.
|
||||
|
||||
{{{class="prettyprint"
|
||||
# Print Dell Service Tag
|
||||
getdst() {
|
||||
if [[ "$1" = "-l" ]]; then
|
||||
printf "http://www.dell.com/support/home/us/en/04/product-support/servicetag/%s\n" "$(getdst)"
|
||||
else
|
||||
sudo dmidecode -s system-serial-number
|
||||
fi
|
||||
}
|
||||
}}}
|
||||
|
||||
As an added bonus, the `-l` option will print the url for that product's support page.

I want the default PulseAudio sink to change to HDMI when HDMI is plugged in, and back to analog when disconnected.
|
||||
|
||||
Changing the default sink in pulse is as easy as running `pacmd set-default-sink <sink id>` where `<sink id>` is the id of the desired sink. Unfortunately, this is another situation where the id might change unexpectedly. We also don't have an easy interface to determine the id number from a name like we did with `xinput(1)`, so we're forced to parse the output of `pacmd list short` like so:

|
||||
}}}
|
||||
|
||||
This command lists all sinks in short form, then greps for a line containing "hdmi", uses grep to only print the first character (the sink id), then sets the default sink with `pacmd(1)`. Since this will also need to be run any time the display configuration changes, a function is, again, appropriate:

This allows you to change the default PulseAudio sink with `setpasink <name>` where `<name>` is any arbitrary string that is unique to the line that corresponds to the desired sink in the output of `pacmd list short`.
