batch resize images using find, xargs and convert

Posted 02-20-2011 at 04:30 PM by dr_agon

Tags batch, convert, find, resize, xargs

applies to: linux, find, xargs, convert, image processing

'convert' command, which is a part of ImageMagick package can be used for image resizing, but it lacks ability to process multiple files (in version of ImageMagick 6.5.7-8 2010-12-02). Instead of writing a shell script you can use find and xargs commands to collect filenames and invoke convert with one filename at a time, like this:

Code:

find -iname "*.jpg" -printf "%f\0" \
 | xargs -0 -I {} convert

...with each new kernel, it seems.

A while back, when I was still running with kernel 2.6.34/35 (and earlier) on my lappy, PowerTOP would show idle power usage anywhere from 10.x W to the occasional dip into the single-digits. Now on kernel 2.6.37, it never goes below 11 W, and sometimes hovers around 12...this annoys me, because it does take a hit on my lappy's battery life (what once was 4+ hours is now 3-

Homebrew paranoia frontend ( CLI ) for audiobooks

Posted 02-19-2011 at 05:16 PM by William (Dthdealer) (Whaling the FOSS)

I've had my troubles with GUI audio CD rippers lately, whether it be DBUS connection issues or lack of 'codecs' for cdda or wav ( sounds as weird as it is ). On top of that the rip-one-at-a-time strategy was too time consuming for the repetitive audio book ripping I am doing, which involved placing four disc rips under the same title.

So I wrote a shell script that does most of the work for me

Code:

#!/bin/bash

Replaced dovecot with courier and my private email server seems to work better than before.

Still have to address some problems with sql-ledger, but I have some notes as to what to do.

Ubuntu is beginning to upset me again. I went to "connect to server" and there were no options. There were before I upgraded. Why was that not included as part of the upgrade. I am tired of fixing mickey mouse stuff on ubuntu. Oh that's right Mark Shuttleworth is a mac user....
