ostree-cat - Man Page

ostree cat {COMMIT} {PATH...}

This command functions much like the typical Unix "cat" command, in that it displays the contents of a file, or concatenates them given two or more files​. However, this command requires the user to specify a commit - a checksum or refspec corresponding to a given build​. If you use a refspec, OSTree will refer to the most recent commit, unless you specify a parent build using the carat (^) at the end of the refspec​. It will then operate the command in that given commit​.

$ ostree cat my-branch helloworld​.txt

        Hello, world!
