get newest jpg picture in a folder

cp `ls -x1tr *.jpg | tail -n 1` newest.jpg
search the newest *.jpg in the directory an make a copy to newest.jpg. Just change the extension to search other files. This is usefull eg. if your webcam saves all pictures in a folder and you like the put the last one on your homepage. This works even in a directory with 10000 pictures.

  • Usage example: newest Desktop/* Replace "-nt" with "-ot" for oldest. Run shopt -s dotglob first to include dotfiles.

  • This takes a webcam picture every everytime the mouse is moved (waits 10 seconds between checking for movement) and stores the picture wherever you want it. Ideas: Use in conjunction with a dropbox type application to see who is using your computer Use /dev/input/mice if /dev/input/mouse* doesn't work Use the bones of this to make a simple screensaver

    while true; do sudo cat /dev/input/mouse0|read -n1;streamer -q -o /tmp/cam.jpeg -s 640x480 > /dev/null 2>&1; sleep 10;done

  • If you have a folder with thousand of files and want to have many folder with only 100 file per folder, run this. It will create 0/,1/ etc and put 100 file inside each one. But find will return true even if it don't find anything ... Show Sample Output


    -1
    folder=0;mkdir $folder; while find -maxdepth 1 -type f -exec mv "{}" $folder \; -quit ; do if [ $( ls $folder | wc -l ) -ge 100 ]; then folder=$(( $folder + 1 )); mkdir $folder; fi ; done

  • Works recusivley in the specified dir or '.' if none given. Repeatedly calls 'find' to find a newer file, when no newer files exist you have the newest. In this case 'newest' means most recently modified. To find the most recently created change -newer to -cnewer. Show Sample Output


    1
    newest () { DIR=${1:-'.'}; CANDIDATE=`find $DIR -type f|head -n1`; while [[ ! -z $CANDIDATE ]]; do BEST=$CANDIDATE; CANDIDATE=`find $DIR -newer "$BEST" -type f|head -n1`; done; echo "$BEST"; }

What Others Think

If the underlying filesystem permits it, you could save space by creating a link instead. Then the command would be: ln -s $(ls -x1tr *.jpg | tail -n 1) newest.jpg where I've replaced the backticks with the less evil $( ) syntax and am making a symbolic link with the -s option, although a hard link would be fine too.

Never parse ls: http://mywiki.wooledge.org/ParsingLs To find the newest file do this instead: http://mywiki.wooledge.org/BashFAQ/099

@ Psychodad, you just made my day. @ dennisw, thanks for the heads up. In my case I just need it for one file at a time in a specific folder, but I'll definitely follow your tip. clockworkpc
