Why /usr/local/scipts?

Why not /usr/lib/<your name>/scripts?

I dunno -- I'm at odds with wondering why /usr/local exists at all.

Anyway, here's mine:

bounceweb

#!/bin/bash
/etc/init.d/apache2 restart
/etc/init.d/postgresql-7.4 restart

bounceswap -- I use a swap file instead of a partition

#!/bin/bash
swapoff /swapfile
swapon /swapfile
cat /proc/swaps

I use this one to switch between PHP 4 and 5. Usually I work on five, but since most hosters out there still have 4 I have to test my stuff on that too, especially my classes which I always write for PHP5 and then backport to 4.

Save MBR and partition table of a disk:

Restore MBR and partition table to a disk:

I've got a script that logs bandwidth spent via ppp network interface whenever I disconnect using a "hang" command I also made:

This is in /etc/ppp/ppplog/ppptraf.sh

It gathers ppp bandwidth information using ifconfig.

The hang command is simply a script located at /usr/bin/hang that looks like this:

So it basically runs ppptraf.sh before killing pppd so that it logs the bandwidth information before it is lost.

Also, less significant is a hail command which I use instead of having to manually start both network interfaces whenever connecting to the internet (since I use both ppp and dvb interfaces, where ppp is for my EDGE modem and dvb is for my satelite card for satelite downstream connection).

So, the hail command starts both:

calling hail.sh (because then hail can release terminal for other commands to be issued afterwards).

(probably not the sexiest solution, but hey..)

So, when I connect to the internet I usually just say "sudo hail" and I'm online. When disconnecting I say "sudo hang" and it logs my traffic from ppp to /mnt/data/ppp-traffic.log for my later inspection and kills ppp. DVB connection doesn't need to be killed however since it doesn't work without ppp anyway, it is just a satelite downstream used through a proxy.

I think this is pretty much the only meaningful thingie coming close to some sort of scripting/programming that I've done, except maybe for the libervis and nuxified site designs.

Cheers

I have quite a few of them. $HOME/bin is my preferred place. I'm not on my box so I can't post any of em. One of them takes a list of mp3/ogg files and burns a cd out of em, another cool one will take a command and log all output of it (stdout and/or stderr) to a file, very useful with startx. Can't really remember any more, I just make and use em without thinking about it. And many things other people would put into scripts are quite trivial for me so scripting it is a bother. And I can conjure up some crazy for and while loops too! I have rewritten quite a few utilities from coreutils and util-linux as shell scripts. Not much work to replace several MBs of bins with a couple KBs of POSIX compliant shell script. I wonder how many people realize how unnessecary the cat utility is...

Can you post the smaller ones and link to all of them?

some small scripts on my home page:
http://jollybox.de/toolbox/index.en.php

and

useful for civilizing stray wmv9's

I updated my sizeof script to handle multiple files/directories.

For some reason I couldn't post them.. so I'll post later when I have them uploaded and linked here.

*cough* yeah, I write a script for anything.
I have a lot more but they're more or less useless.

This is the script I use to find the sum total size of my server backups:

srvbksize.sh

#!/bin/bash
#
# Server Backup Size - srvbksize.sh
#
# Iestyn Pryce
# 25/04/07

IFS='

umask $UMASK

PROGRAM=srvbksize.sh

DIR=~/backups

total=0

for f in `ls -al $DIR | grep -v "\-backup-" | fgrep backup- | sed s/' '/#/g |sed s/###/#/g | sed s/##/#/g | cut -d'#' -f 5 `
do total=$(expr $total + $f); 
done

# Make human readable as MB #
remainder=`expr $total % 1048576`
total=`expr $total / 1048576`

echo $total.$remainder MB is the sum total of your server backups 

I need to reorganize my scripts directory. I've also updated a lot of them.. mm I'll get around to reposting them[, in a better fashion too].
