|
# -w, --write-out <format> Use output FORMAT after completion
|
|
# example:
|
|
curl -w %{size_header} --silent -o /dev/null http://gogle.com # print size of header when you accessing google.com
|
|
|
|
# FORMAT supported:
|
|
# %{content_type} # shows the Content-Type of the requested document, if there was any.
|
|
# %{filename_effective} # shows the ultimate filename that curl writes out to.
|
|
# This is only meaningful if curl is told to write to a file with
|
|
# the --remote-name or --output option. It's most useful in combination
|
|
# with the --remote-header-name option.
|
|
# %{ftp_entry_path} # shows the initial path curl ended up in when logging on to the remote FTP server.
|
|
# %{response_code} # shows the numerical response code that was found in the last transfer.
|
|
# %{http_connect} # shows the numerical code that was found in the last response (from a proxy)
|
|
# to a curl CONNECT request.
|
|
# %{local_ip} # shows the IP address of the local end of the most recently done connection—can
|
|
# be either IPv4 or IPv6
|
|
# %{local_port} # shows the local port number of the most recently made connection
|
|
# %{num_connects} # shows the number of new connects made in the recent transfer.
|
|
# %{num_redirects} # shows the number of redirects that were followed in the request.
|
|
# %{redirect_url} # shows the actual URL a redirect would take you to when an HTTP request
|
|
# was made without -L to follow redirects.
|
|
# %{remote_ip} # shows the remote IP address of the most recently made connection—can be
|
|
# either IPv4 or IPv6.
|
|
# %{remote_port} # shows the remote port number of the most recently made connection.
|
|
# %{size_download} # shows the total number of bytes that were downloaded.
|
|
# %{size_header} # shows the total number of bytes of the downloaded headers.
|
|
# %{size_request} # shows the total number of bytes that were sent in the HTTP request.
|
|
# %{size_upload} # shows the total number of bytes that were uploaded.
|
|
# %{speed_download} # shows the average download speed that curl measured for the complete download
|
|
# in bytes per second.
|
|
# %{speed_upload} # shows the average upload speed that curl measured for the complete upload in
|
|
# bytes per second.
|
|
# %{ssl_verify_result} # shows the result of the SSL peer certificate verification that was requested.
|
|
# 0 means the verification was successful.
|

|
|
# to the remote host was completed.

|
|
# host (or proxy) was completed.
|
|
# %{time_namelookup} # shows the time, in seconds, it took from the start until the name resolving was completed.
|
|
# %{time_pretransfer} # shows the time, in seconds, it took from the start until the file transfer was just about
|
|
# to begin. This includes all pre-transfer commands and negotiations that are specific to
|
|
# the particular protocol(s) involved.
|
|
# %{time_redirect} # shows the time, in seconds, it took for all redirection steps including name lookup, connect,
|
|
# pre-transfer and transfer before the final transaction was started. time_redirect shows
|
|
# the complete execution time for multiple redirections.
|
|
# %{time_starttransfer} # shows the time, in seconds, it took from the start until the first byte was just about to
|
|
# be transferred. This includes time_pretransfer and also the time the server needed
|
|
# to calculate the result.
|
|
# %{time_total} # shows the total time, in seconds, that the full operation lasted. The time will be displayed
|
|
# with millisecond resolution.
