Bash – mysql backup script

This script backs up all databases on the server it’s running on. Usually ran as a cron job.

Hope someone else can use this as well.

#!/bin/bash
# Backup ALL mysql databases
# by crouse - http://archlinux.me/crouse
x=`mysql --user=root --password=REMOVED -B -e "show databases"  | wc -l `; y=$((x-2));
for i in `mysql --user=root --password=REMOVED -B -e "show databases"  | tail -${y}`; do
mysqldump --opt --user=root --password=REMOVED $i | gzip -9 > /root/MYSQLBACKUPS/$i.`date --iso-8601`-mysqlbackup.gz
ls -t /root/MYSQLBACKUPS/$i.* | awk 'NR>7' | xargs rm -f
done
# Mail updates

Bash – a quick stock quote function

Wrote this and stuck it in my .bashrc file so I could get a realtime stock quote quickly from my shell sessions.

stock ()
{
lynx -dump "http://www.google.com/finance?client=ob&amp;q=${1}" | sed 's/.*']'//' | \
perl -00ne "print if /Watch this stock/i" | sed 's/Watch this stock//' | sed 's/Disclaimer//' | \
sed '/^$/d' | sed 's/Currency in USD//'
}

TIP: Ever get those strange characters in your console ?

Ever get those strange looking little buggers in your console after installing Arch and firing up the terminal ?
Something like this –
[crouse@archie ~]$ pstree
init─┬─6*[agetty]
├─crond
├─httpd───11*[httpd]
├─mysqld_safe───mysqld───9*[{mysqld}]
├─sshd─┬─sshd───sshd───bash───su───bash
│ └─sshd───sshd───bash───pstree
├─syslog-ng───syslog-ng
├─udevd───udevd
└─vmtoolsd

Simply add the following to your .bashrc and close your terminal window and open it up again, or source the .bashrc file again.
export LC_ALL=C

[crouse@archie ~]$ pstree
init-+-6*[agetty]
|-crond
|-httpd---11*[httpd]
|-mysqld_safe---mysqld---9*[{mysqld}]
|-sshd-+-sshd---sshd---bash---su---bash
| `-sshd---sshd---bash---pstree
|-syslog-ng---syslog-ng
|-udevd---udevd

Getting a listing of blogs on Archlinux.me

An easy way to get a listing of all the current blogs in the system.

for data in $dbase ;
do
echo "http://archlinux.me${data}"
