So I’ve changed it around to use stat and maybe exif data in the future: function rsyncFile() { for img in ${PATH}/* do echo “${img}” ymd=`${STAT} -c %y “${img}” | ${CUT} -d’ ‘ -f1 | ${SED} -e ‘s/-/./g’` year=`echo ${ymd} | ${AWK} -F. ‘{print $1}’` month=`echo ${ymd} | ${AWK} -F. ‘{print $2}’` day=`echo ${ymd} | ${AWK} -F. ‘{print $3}’` picturesPath=/home/ryan/Pictures/${year}.${month}/${year}.${month}.${day} ${MKDIR} -p ${picturesPath} echo ${RSYNC} -av “${img}” ${picturesPath} ${RSYNC} -av “${img}” ${picturesPath} done } == End Update Here’s a quick bash script I wrote to copy stuff from my camera memory card to my Pictures directory but so that it will create it in the format that I like: /home/user/Pictures/year.twodigitmonth/year.twodigitmonth.twodigitday So Feb 1st, 2013 pictures would be in directory: /home/user/Pictures/2013.02/2013.02.01 The script is really just a function that takes 3 arguments, the month in ls format, the two digit representation of the month, and the year: #!/bin/bash PATH=/media/Canon_DIGITAL/DCIM/100CANON/ PICTURES=/home/user/Pictures MONTHS="Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec" AWK=/usr/bin/awk GREP=/bin/grep LS=/bin/ls MKDIR=/bin/mkdir RSYNC=/usr/bin/rsync function rsyncMonth() { month=${1} numonth=${2} year=${3} echo $month $numonth $year for img in `${LS} -l ${PATH} |${GREP} ${month}|${AWK} '{print $NF}'` do day=`${LS} -ld ${PATH}/${img} | ${AWK} '{print $7}'` if [ ${day} -lt 10 ] then day="0${day}" fi picturesPath=${PICTURES}/${year}.${numonth}/${year}.${numonth}.${day} ${MKDIR} -p ${picturesPath} ${RSYNC} -av ${PATH}/${img} ${picturesPath} done } and you would call it below the function like: rsyncMonth Jan 01 2013 to get all the pictures off the memory card that match January 2013.

Here’s pretty much the steps I did: Unmount the partition: umount /tmp Make an image of the partition to work with on a partition that had enough space for it: cd /var/preserve dd if=/dev/mapper/vg_01-lv_tmp of=tmp_fs.img Or if you need to do it over the network you need to: ssh root@server “dd if=/dev/mapper/vg_01-lv_tmp” > tmp_fs.img Download and compile ext4magic at http://developer.berlios.de/projects/ext4magic/ yum install e2fsprogs-devel uuid-devel libblkid-devel file-devel wget http://prdownload.berlios.de/ext4magic/ext4magic-0.3.1.tar.gz tar -xvpf ext4magic-0.3.1.tar.gz cd ext4magic-0.3.1 ./configure make Since the files were delete 4 days ago, I decided to R recover (everything) after 5 days ago and before 2 days ago. sudo src/ext4magic -R \ -a $(date -d “-5day” +%s) \ -b $(date -d “-2day” +%s) \ -d /var/preserve/RECOVER /var/preserve/tmp_fs.img Boom, the files that I was looking for were in a MAGIC-1 directory since the missing files were in directory tree that all got deleted.

Check out my okayryan username. So far I just have a named check zone wrapper and a fedora 18 ansible playbook. Posted in software | Tagged github | Leave a comment one liner to simply check for pictures and video in my pictures home directory Posted on December 29, 2012 by Ryan I used this today to just check and make sure what files I can remove off my sdcard. I just simply checked the filesize on the files and make sure it was the same in my Pictures directory in my home directory. If I wanted to be very fancy, I could have done a sha1sum on the files to make sure the hashes were completely the same. /media/ryan/8765-4321/DCIM/146EKZi8$ for a in `ls`; do ls -l $a; \ find /home/ryan/Pictures -name $a -exec ls -l '{}' \; ; done &> /tmp/kodak Posted in software | Tagged find , ls | Leave a comment publish photo shotwell piwigo invalid username password with & symbol Posted on November 23, 2012 by Ryan Just submitted a bug report for shotwell on Ubuntu 12.10: Basically, when trying to publish a picture to my piwigo website, I get an invalid username or password if my password has a & in it. Piwigo version: 2.4.5 shotwell version: 0.13.0 Ubuntu version: 12.10 Work around is just not use the & symbol in your password and it works fine.

Unfortunately, when I have to get rid of newlines, I always end up doing a macro that join lines and does an edit on them. Now you don’t if you use the translate (tr) tool found in linux. You can use tr for other purposes by checking out the man page, but I pretty much just use it to strip out all the newlines in a text file. I simply just cat out a file and pipe it through tr to do my work: To change all the newlines into semicolons: cat file.txt | tr '\n' ';' To change all the newlines into spaces: cat file.txt | tr '\n' ' ' Just redirect the output to file if you want to save it. Replace the newline with the number 3 and output the results to file3.txt: cat file.txt | tr '\n' '3' > file3.txt Posted in software , tips | Tagged convert , newlines , text , tr , translate | Leave a comment Easy gcc compile using download_prerequisites in contrib and compiling gcc on CentOS 6 x86_64 Posted on September 15, 2012 by Ryan For the longest time, I never noticed that there was a contrib directory in gcc’s source archive. Not only that, but the download_prerequisites script does an amazingly simple job that saves me minutes off a single gcc compile. What does it do? download_prerequisites actually downloads the exact version of gmp, mpc, and mpfr that gcc needs to build. The extra boot is that it sets up the symbolic links and so when you do the configure and make for gcc, it will very much build the dependicies without fail almost every time. Here’s an example CentOS 6 x86_64 that I’ve done the other day tar -jxvpf gcc-4.7.1.tar.bz2 cd gcc-4.7.1 mkdir objdir cd contrib ./download_prerequisites cd ../objdir ./configure --build=x86_64-pc-linux-gnu --prefix=/home/ryan/software/gcc/4.7.1 --disable-multilib make make install Posted in software | Tagged gcc , opensource , protip , software | Leave a comment Recovered deleted pictures from canon sdcard Posted on August 30, 2012 by Ryan I was able to use the ZAR data recovery software to restore an entire directory full of images after someone deleted their folder via the camera. http://www.z-a-recovery.com/download.htm Pretty good software and I like their name of “Zero Assumption Recovery.” Remember that if your data isn’t in 2 places, it doesn’t exist anywhere, make backups ASAP!
