echo json over command line into file
To preserve double quotes you need to surround your variable in single quotes, like so:
json='{"commit_id": "b8f2b8b", "environment": "test", "tags_at_commit": "sometags", "project": "someproject", "current_date": "09/10/2014", "version": "someversion"}'echo $json > versions.jsonTake into account that this method will not display variables correctly, but instead print the literal $variable.
If you need to print variables, use the cat << EOF construct, which utilizes the Here Document redirection built into bash. See man bash and search for "here document" for more information.
Example:
commit="b8f2b8b"environment="test"...etccat << EOF > /versions.json{"commit_id": $commit, "environment": $environment, "tags_at_commit": $tags, "project": $project, "current_date": $date, "version": $version}EOFIf you're lookin for a more advanced json processing tool that works very well with bash, I'd recommend jq (http://stedolan.github.io/jq/manual/)
