Open Random File Command Line Osx
Ever want to select a random file on the command line? Or just randomize anything? Well it’s possible using
We can use the
shuf command to shuffle any input from stdin. Use
ls | shuf -n1
to pull a random file. The
-n1 switch tells shuf to select only the first file. Without it you’ll get a totally randomized list of the entire directory. Neat!
shuf is a utility from GNU coreutils. It should be available out of the box on any regular linux install, but for OS X you will have to take an extra step.
On OS X, coreutils can be installed on the commandline using homebrew:
brew install coreutils
Important Note for OSX
Now that coreutils is installed you can call each coreutils application by its prefixed name, just add a g in front:
ls | gshuf -n1
You can use the output of this command to send it to other applications.
For example, on OS X we can use the
open command to actually open the random file we’ve selected:
open $(ls | gshuf -n1)
