       ostree-cat - Display or concatenate contents of files


       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!
