How to print previous command?

497 find . -name '*.jpg' -and -size +2000k -exec cp -v {} ./final/ \;
767 h | grep find
770 h | grep find

To access Nth command without execution, add “:p” to !N.
$ !497:p
It would display

find . -name '*.jpg' -and -size +2000k -exec cp -v {} ./final/ \;

Then, to reload it on prompt, press Ctrl+p for command modification.

$ find . -name '*.jpg' -and -size +2000k -exec cp -v {} ./final/ \;

Apt-Pinning for Beginners It explains how to manage stable, testing, and unstable packages all together.

When downgrade or upgrade of package fails due to unmet dependency, the safe and simplest solution is to download package using .deb file. It has two steps:
locate and download the package file
dpkg -i package_name.deb

How to get rid of package list update error like “Failed to fetch …”?

When I install new package, the first thing is to update the package list. Sometimes aptitude or apt-get update creates weird errors. Here is one of them.
Failed to fetch http://ftp.jp.debian.org/debian/dists/stable/main/binary-amd64/Packages: 403 Forbidden [IP: 203.178.137.175 80]

Replace http to ftp in site name.

deb ftp://ftp.jp.debian.org/debian/ testing main contrib non-free
deb-src ftp://ftp.jp.debian.org/debian/ testing main contrib non-free

Troubleshooting and system modification

Pulseaudio Flash sound bug
(9/27/2012;)

I’ve been experiencing sound issue on Flash video on Google Chrome since Pulseaudio installation.

I applied the following method and it worked out.

http://askubuntu.com/questions/122148/flash-in-browsers-does-not-play-sound-accurately-using-pulse-network-audio

PULSE_SERVER=192.168.1.100:4713 google-chrome &

$ more /etc/environment
# Pulseaudio Flash sound fix
PULSE_SERVER=192.168.1.100:4713

Add two lines in /etc/profile
# Pulseaudio
. /etc/environment

Installed kexec and set up warm boot.

Installed bootlogd (2.88)

Added Caps lock function to Colemak keyboard layout.

(9/9/2012;)
Installed AMD Catalyst driver 12.6 for Xorg.

(8/25/2012;9/2012;)
Replaced pulseaudio with alsa due to no sound issue after reboot.
The symptom was pulseaudio fails to recognize the sound card for audio output. It selected Dummy output. Is it misconfiguration of group access related to sound device files?

Reinstalled pulseaudio after removing alsa packages. pulseaudio has been running fine.
How to turn on and off auto mute? I use alsamixer to do it.

Everything works fine as of today.

One site triggers Java plug-in update to 1.7.5. I’ll update it when other sites recommend Java 1.7.5 too.

[Solved] libreoffice shows broken menu and status bar.

Something was serious wrong when I started it. And it showed void menu bar which on top of the window. (Bug #666565)

It seems libcairo2 1.10.2-7 is only solution to fix it for now. 1.12.2-2 on testing, 1.18.x on unstable has the same problem – broken menu and status bar.

I followed the normal procedure to downgrade libcairo2 1.10.2-7, it failed due to unmet dependency both aptitude and apt-get unless I would remove hundreds packages.

I located libcairo2 1.10.2-7 (http://packages.debian.org/squeeze-backports/libcairo2) because I installed libreoffice from squeeze-backports and has been using it almost a year.

I downloaded libcairo2_1.10.2-7~bpo60+1_amd64.deb from a mirror site, and installed it using dpkg.

$ sudo dpkg -i /home/penguin/Downloads/libcairo2_1.10.2-7~bpo60+1_amd64.deb
dpkg: warning: downgrading libcairo2:amd64 from 1.12.2-2 to 1.10.2-7~bpo60+1

First letter -> desired package state ("selection state"):

u ... unknown

Second letter -> current package state:

The installer removed vlc and libvlccore4 apparently.

During boot right after fresh installation, network file system daemons would hang on. I removed NFS packages after log in rescue mode.

$ sudo apt-get --purge remove nfs-kernel-server nfs-common portmap

[Solved] sudo doesn’t work.

Add /usr/local/sbin, /usr/sbin, /sbin directories in PATH variable in /etc/profile as root.

# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), …).

if [ "`id -u`" -eq 0 ]; then
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/
games:/usr/games"
fi
export PATH

[Solved]suspend doesn’t work

Removing hal and hal-info packages as Debian Wiki didn’t solve it.

Turned on the debug mode of pm-utils by adding “export PM_DEBUG=true”
on /usr/lib/pm-utils/pm-functions file as below.


#!/bin/sh
# vim:noexpandtab

# Default values go here. It is important to _not_ initialize some
# variables here. They are:
#
# PM_CMDLINE
# RESUME_MODULES
#
# for great debugging!
# __8/10/2012__
export PM_DEBUG=true

[ "${PM_DEBUG}" = "true" ] &

failed suspend traced back to 56nfs, which is the script file for Network File Services that I replicated while ago. I moved it to /etc/pm/ directory. Suspend works again.
