I guess this could be a cross-platform format but you could also just store it as a sequence of commands echo "Hello, world!" > file mkdir -p dir/subdir echo -n "Content.\n" > dir/subfile ln -s "target path" link printf '#!/bin/sh\necho Howdy!' > script chmod +x script Would be the same as what's in the readme: { "file": "Hello, world!", "dir": { "subfile": "Content.\n", "subdir": {} }, "symlink": ["link", "target path"], "script": ["script", "#!/bin/sh\necho Howdy!"] }
