Functions

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

get newest jpg picture in a folder

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.

Alternatives

There are 2 alternatives - vote for the best!

Know a better way?

If you can do better, submit your command here.

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:

@ 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.
