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.
