ostree-cat1
Display or concatenate contents of files
Usage
ostree cat
COMMIT
PATH ...
Overview
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.
Examples
$ ostree cat my-branch helloworld.txt
Hello, world!
