Blogging Ottinger (tim)Today’s Top Ten Command Line Tools
This is all the rage lately, so I’m doing it too:
[0]tottinge@clicky:~$ history|awk '{a[$2]++} END{for(i in a){printf \"%5d\t%s\n\",a[i],i}}'|sort -rn|head
119 sudo
53 ls
34 hpodder
30 cd
19 vi
18 ping
16 exit
13 df
12 apt-cache
10 ./savepower.sh
Sudo is almost always for “sudo ifdown ath0; sudo ifup ath0=ath0-whatever”. I am mobile, and often switching wireless networks between home, airports, panera bread, church, taco john, goldentree at hotels, and other people’s offices.
savepower.sh is a script I made to put my laptop in low-power mode. I mostly took the advice from my copy of powertop. It seems to extend my laptop battery quite a bit, and it looks something like this:
#!/bin/bash -x
SERVERS_TO_STOP=\"cupsys mysql bluetooth apache2 bittorrent mono-xsp tomcat5\"
for server in ${SERVERS_TO_STOP}
do
sudo invoke-rc.d ${server} stop
done
sudo bash -c \"echo 5 > /proc/sys/vm/laptop_mode\"
sudo bash -c \"echo 1 > /sys/module/snd_ac97_codec/parameters/power_save\"
sudo bash -c \"echo 1500 > /proc/sys/vm/dirty_writeback_centisecs\"
sudo bash -c \"echo disabled > /proc/acpi/ibm/bluetooth\"
