1 Long: write-out 2 Short: w 3 Arg: <format> 4 Help: Use output FORMAT after completion 5 --- 6 Make curl display information on stdout after a completed transfer. The format 7 is a string that may contain plain text mixed with any number of 8 variables. The format can be specified as a literal "string", or you can have 9 curl read the format from a file with "@filename" and to tell curl to read the 10 format from stdin you write "@-". 11 12 The variables present in the output format will be substituted by the value or 13 text that curl thinks fit, as described below. All variables are specified as 14 %{variable_name} and to output a normal % you just write them as %%. You can 15 output a newline by using \\n, a carriage return with \\r and a tab space with 16 \\t. 17 18 The output will be written to standard output, but this can be switched to 19 standard error by using %{stderr}. 20 21 .B NOTE: 22 The %-symbol is a special symbol in the win32-environment, where all 23 occurrences of % must be doubled when using this option. 24 25 The variables available are: 26 .RS 27 .TP 15 28 .B content_type 29 The Content-Type of the requested document, if there was any. 30 .TP 31 .B filename_effective 32 The ultimate filename that curl writes out to. This is only meaningful if curl 33 is told to write to a file with the --remote-name or --output 34 option. It's most useful in combination with the --remote-header-name 35 option. (Added in 7.26.0) 36 .TP 37 .B ftp_entry_path 38 The initial path curl ended up in when logging on to the remote FTP 39 server. (Added in 7.15.4) 40 .TP 41 .B http_code 42 The numerical response code that was found in the last retrieved HTTP(S) or 43 FTP(s) transfer. In 7.18.2 the alias \fBresponse_code\fP was added to show the 44 same info. 45 .TP 46 .B http_connect 47 The numerical code that was found in the last response (from a proxy) to a 48 curl CONNECT request. (Added in 7.12.4) 49 .TP 50 .B http_version 51 The http version that was effectively used. (Added in 7.50.0) 52 .TP 53 .B local_ip 54 The IP address of the local end of the most recently done connection - can be 55 either IPv4 or IPv6 (Added in 7.29.0) 56 .TP 57 .B local_port 58 The local port number of the most recently done connection (Added in 7.29.0) 59 .TP 60 .B num_connects 61 Number of new connects made in the recent transfer. (Added in 7.12.3) 62 .TP 63 .B num_redirects 64 Number of redirects that were followed in the request. (Added in 7.12.3) 65 .TP 66 .B proxy_ssl_verify_result 67 The result of the HTTPS proxy's SSL peer certificate verification that was 68 requested. 0 means the verification was successful. (Added in 7.52.0) 69 .TP 70 .B redirect_url 71 When an HTTP request was made without --location to follow redirects (or when 72 --max-redir is met), this variable will show the actual URL a redirect 73 \fIwould\fP have gone to. (Added in 7.18.2) 74 .TP 75 .B remote_ip 76 The remote IP address of the most recently done connection - can be either 77 IPv4 or IPv6 (Added in 7.29.0) 78 .TP 79 .B remote_port 80 The remote port number of the most recently done connection (Added in 7.29.0) 81 .TP 82 .B scheme 83 The URL scheme (sometimes called protocol) that was effectively used (Added in 7.52.0) 84 .TP 85 .B size_download 86 The total amount of bytes that were downloaded. 87 .TP 88 .B size_header 89 The total amount of bytes of the downloaded headers. 90 .TP 91 .B size_request 92 The total amount of bytes that were sent in the HTTP request. 93 .TP 94 .B size_upload 95 The total amount of bytes that were uploaded. 96 .TP 97 .B speed_download 98 The average download speed that curl measured for the complete download. Bytes 99 per second. 100 .TP 101 .B speed_upload 102 The average upload speed that curl measured for the complete upload. Bytes per 103 second. 104 .TP 105 .B ssl_verify_result 106 The result of the SSL peer certificate verification that was requested. 0 107 means the verification was successful. (Added in 7.19.0) 108 .TP 109 .B stderr 110 From this point on, the --write-out output will be written to standard 111 error. (Added in 7.63.0) 112 .TP 113 .B stdout 114 From this point on, the --write-out output will be written to standard output. 115 This is the default, but can be used to switch back after switching to stderr. 116 (Added in 7.63.0) 117 .TP 118 .B time_appconnect 119 The time, in seconds, it took from the start until the SSL/SSH/etc 120 connect/handshake to the remote host was completed. (Added in 7.19.0) 121 .TP 122 .B time_connect 123 The time, in seconds, it took from the start until the TCP connect to the 124 remote host (or proxy) was completed. 125 .TP 126 .B time_namelookup 127 The time, in seconds, it took from the start until the name resolving was 128 completed. 129 .TP 130 .B time_pretransfer 131 The time, in seconds, it took from the start until the file transfer was just 132 about to begin. This includes all pre-transfer commands and negotiations that 133 are specific to the particular protocol(s) involved. 134 .TP 135 .B time_redirect 136 The time, in seconds, it took for all redirection steps including name lookup, 137 connect, pretransfer and transfer before the final transaction was 138 started. time_redirect shows the complete execution time for multiple 139 redirections. (Added in 7.12.3) 140 .TP 141 .B time_starttransfer 142 The time, in seconds, it took from the start until the first byte was just 143 about to be transferred. This includes time_pretransfer and also the time the 144 server needed to calculate the result. 145 .TP 146 .B time_total 147 The total time, in seconds, that the full operation lasted. 148 .TP 149 .B url_effective 150 The URL that was fetched last. This is most meaningful if you've told curl 151 to follow location: headers. 152 .RE 153 .IP 154 If this option is used several times, the last one will be used. 155
