Basic Usage

urp takes URLs as input, and outputs URLs or features of URLs depending on its options. It takes URLs specified as arguments and newline-delimited URLs from standard input.

$ urp -s https://google.com
https
$ echo 'https://google.com' | urp -s
https
$ urp -D /search -Q q=urp 'https://google.com'
https://google.com/search?q=urp

Printing URL Features

If any of these options are specified, urp will abandon its default behavior of printing full URLs and instead print the features specified.

-s, --print-scheme

Print scheme.

-u, --print-username

Print username.

-w, --print-password

Print password.

-o, --print-hostname

Print hostname.

-p, --print-port

Print port.

-a, --print-authority

Print authority. The authority is comprised of the username, password, hostname, and port.

-d, --print-path

Print path.

--print-params

Print params.

-q, --print-query

Print query string.

--print-query-names

Print query parameter names.

--print-query-values

Print query parameter values.

-f, --print-fragment

Print fragment.

-g QUERY, --print-query-value QUERY

Print value of query parameter.

Modifying URLs

Modifying features of URLs will cause the changes to be reflected in the output, both through the printing options and through default behavior.

-S SCHEME, --scheme SCHEME

Set scheme to SCHEME.

-U USERNAME, --username USERNAME

Set username to USERNAME.

-W PASSWORD, --password PASSWORD

Set password to PASSWORD.

-O HOSTNAME, --hostname HOSTNAME

Set hostname to HOSTNAME.

-P PORT, --port PORT

Set port to PORT.

-D PATH, --path PATH

Set or append path as PATH. If PATH begins with a / then the path is replaced. Otherwise it is appended to the existing path.

--params PARAMS

Set params to PARAMS.

--query QUERY

Set query to QUERY.

-Q PAIR, --append-query PAIR

Append query parameter. PAIR should have the format NAME=VALUE.

-F FRAGMENT, --fragment FRAGMENT

Set fragment to FRAGMENT.

Altering Behavior

By default, urp outputs URL-encoded fields where necessary and preserves the order of query parameters.

--no-url-encoding

Disable URL encoding in output.

--no-query-params

Disable query parameter parsing. urp will not try to parse NAME=VALUE pairs from queries.

--sort-query

Sort query parameters by name in output.

-x QUERY, --ignore-query QUERY

Ignore query parameter.

Each URL processed emits a record, consisting of multiple fields. By default, records are separated with newlines and fields are separated with spaces. To change the record separator, set the RS environment variable. To change the field separator, set the OFS environment variable.
