JQ to filter JSON by value

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)

Common Options

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.

	The output will be something like that:

	.d..t..g... ./

	# Short alias to allow automated copying of the 1password cli tool command 'op get somewebsite \| jq ...' and then a timed clear on the gnome clipboard
	# TODO: specify designation as an argument and maybe a command to open the website in chrome

	pass=$(op get item $1 \| jq -r '.details.fields[] \| select(.designation=="password").value')

	if [ -n "$pass" ]
	then
	echo $pass \| xclip -selection clipboard
	echo "Password was copied - clipboard will be wiped in 15 seconds"
	sleep 15

	ssh() {
