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.

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: To find the newest file do this instead:

@ 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
