Bash title random Quote routine

robotsu (Robot) — Thu, 24 Apr 2008 19:43:08 GMT

#
#this is a script in my .bash_profile that gets a random
#quote .txt file and assigns it to the terminal title.
#

quote_path="/Users/glynch/Documents/quotes/*"
files=($quote_path)
N=${#files[@]}
((N=RANDOM%N))
randomfile=${files[$N]}
quote=""
while read line; do quote="$quote $line"; done < $randomfile
echo -n -e "\033]0;$quote\007"

Populate titlebar in any term

Populate your titlebar in any term with some useful info such as uname -a, architecture, if you're ROOT or not, etc. In Linux:



#!/bin/bash

HOST_NAME=`hostname -f`

if [ `id -u` = 0 ]; then

OPT=”`uname` (`uname -a | cut -f12 -d’ ‘ -`) - ROOT USER”

else

OPT=”`uname` (`uname -a | cut -f12 -d’ ‘ -`)”

fi

REPLACE=”${HOST_NAME} - ${OPT}”

echo -n -e “\033]0; $REPLACE \007 “

echo “${REPLACE}”

exit 0

Then run this script, and your termtitle will be something like the following:



Servername (Linux / x86_64).

For Solaris it needs to be done a bit differently:



#!/usr/local/bin/bash

HOST_NAME=`uname -a | cut -f2 -d’ ‘ -`

OPT=”(`uname -a | cut -f1 -d’ ‘ -` / `uname -a | cut -f6 -d’ ‘`)”

REPLACE=”${HOST_NAME} - ${OPT}”

echo -n -e “\033]0; $REPLACE \007 “

echo “${REPLACE}”

exit 0

Add/remove things from the OPT= line to customize. To test it, just issue the command on the commandline without the ()'s to see what it'll look like.

Easy extracting html 'title' element from an url



require 'open-uri'



URI.parse('http://google.es').open do |f|

	f.each {|l| if md = (/\s*(.*)\s*<\/title>/iu).match(l) then print md[1] end }
<br />end
