sudo yum remove docker \
                  docker-common \

                  docker-engine

Syntax: cat <filename> | jq -c '.[] | select( .<key> | contains("<value>"))'

Example: To get json record having _id equal 611

cat my.json | jq -c '.[] | select( ._id | contains(611))'

Remember: if JSON value has no double quotes (eg. for numeric) to do not supply in filter i.e. in contains(611)

How to use:

Take the download.sh file and put it into a directory where you want the files to be saved.
cd into the directory and make sure that it has executable permissions (chmod +x download.sh should do it)
Run ./download.sh and wee there it goes. Also if you do not want all the files, just simply comment the ones you do not want.
