List readonly files












2














I need to list or show or query for the files in a folder (well, technically, on a USB drive, but I can navigate to it in Finder/Terminal) that are marked readonly.



All the Google-fu in the world just reveals solutions to change permissions but I don't need to do that.



My Dashcam marks videos/images readonly to save them when I press the button on it, but they're still in a folder with a few hundred MOV files, and I need a simple way to filter down to the ones I am looking for.






terminal finder permission

          List the files and grep for the read-only pattern:



          ls -l | grep '^-r--'



          ^ symbol indicates start the line.



          We are filtering only files here by mentioning ^-, after that looking only for read permission files by specifying r--. If you want to filter read & executable permission files, you can use r-x.



          If you want just the filename, you can use below command



          ls -l | grep '^-r--' | awk 'NF>1{print $NF}'



          Printing the file name using above command works, only if you don't have spaces in file name.

          • Grepping the ls -l is a smart way to do it, but beware that your files might start with -rw-r--r-- with root as the owner, and such files won't be listed, even though they aren't writeable for the user.

          One way is to make use of the -w option in bash to check if the file is writable or not.



          Go into the directory you want to check your files, then enter:



          for RO in $(find . -type f);do [ -r "$RO" ] && [ ! -w "$RO" ] && echo $RO;done
