Determine the extension is present: From the target Mac, launch a terminal session and switch to an elevated shell session using the following command. Next we pipe into the sort command which just puts every thing in order.įinally we pipe into uniq -c which counts each unique line (the file extensions) and prints out the results. Kernel extensions are present that need to be removed for testing deployment via Ivanti MDM. The pattern is just a regex that says look for a dot followed by one or more chars that are not a dot \+, at the end of a line $.

Next we have grep -o ".\+$" the -o tells grep to only output lines that match the pattern, and only output the match. The -type f omits directories from showing up in the list.

jsįirst we have find /some/dir -type f which just limits find to output all the files in the directory recursively. This will print out a nice list like this: 5. Here's one way to print out a list of extensions and the number of files of each type: find /some/dir -type f | grep -o ".\+$" | sort | uniq -c What if you want a listing of all file extensions and the count of files in a directory? js to show up only at the end of the file. js anywhere in the path, so we could improve that script by using a regular expression $ character, for example: find /some/dir | grep -c '\.js$' The above would also match a file, or a directory had. The first character, an en dash ( - ), shows that this is a file. File permissions for the file are shown in the first 11 characters output by the ls command. This will show all user access levels, as well as any extended attributes relevant to macOS. The -c in grep tells it to count the matches, I'm using fgrep here because I'm not using a regex (to avoid escaping the dot). ls -l file.txt Replace file.txt with your own file name. The Kerberos single sign-on (SSO) extension on macOS Catalina10.15 will log users into native apps (for apps that support Kerberos authentication) and sync local user passwords with a directory service such as Microsoft Active Directory. For example you want to know how many js files are in a directory, you can run this: find /some/dir | fgrep -c '.js'

Back in 2004 I wrote up a blog entry showing how to get a count of files by a specific extension.
