jq is a powerful tool to work with JSON from the command-line.
The tool has a lot of functions that makes our live easier.
We can check if a string starts or ends with a given string using the startswith and endswith functions.
We pass the string value we want to see a string value starts with or ends with as the argument to the functions.
The function returns true if the string starts or ends with the given string and false otherwise.
In the following examples we use both functions to check some string values in an array:
$ jq --null-input '["mrhaki", "hubert", "MrHaki"] | [.[] | startswith("mr") or startswith("Mr")]'
[
true,
false,
true
]
$ jq --null-input '["jq!", "JSON"] | [.[] | endswith("!")]'
[
true,
false
]
Written with jq 1.7.
