1 Long: write-out 2 Short: w 3 Arg: <format> 4 Help: Use output FORMAT after completion 5 Category: verbose 6 --- 7 Make curl display information on stdout after a completed transfer. The format 8 is a string that may contain plain text mixed with any number of 9 variables. The format can be specified as a literal "string", or you can have 10 curl read the format from a file with "@filename" and to tell curl to read the 11 format from stdin you write "@-". 12 13 The variables present in the output format will be substituted by the value or 14 text that curl thinks fit, as described below. All variables are specified as 15 %{variable_name} and to output a normal % you just write them as %%. You can 16 output a newline by using \\n, a carriage return with \\r and a tab space with 17 \\t. 18 19 The output will be written to standard output, but this can be switched to 20 standard error by using %{stderr}. 21 22 .B NOTE: 23 The %-symbol is a special symbol in the win32-environment, where all 24 occurrences of % must be doubled when using this option. 25 26 The variables available are: 27 .RS 28 .TP 15 29 .B content_type 30 The Content-Type of the requested document, if there was any. 31 .TP 32 .B filename_effective 33 The ultimate filename that curl writes out to. This is only meaningful if curl 34 is told to write to a file with the --remote-name or --output 35 option. It's most useful in combination with the --remote-header-name 36 option. (Added in 7.26.0) 37 .TP 38 .B ftp_entry_path 39 The initial path curl ended up in when logging on to the remote FTP 40 server. (Added in 7.15.4) 41 .TP 42 .B http_code 43 The numerical response code that was found in the last retrieved HTTP(S) or 44 FTP(s) transfer. In 7.18.2 the alias \fBresponse_code\fP was added to show the 45 same info. 46 .TP 47 .B http_connect 48 The numerical code that was found in the last response (from a proxy) to a 49 curl CONNECT request. (Added in 7.12.4) 50 .TP 51 .B http_version 52 The http version that was effectively used. (Added in 7.50.0) 53 .TP 54 .B json 55 A JSON object with all available keys. 56 .TP 57 .B local_ip 58 The IP address of the local end of the most recently done connection - can be 59 either IPv4 or IPv6 (Added in 7.29.0) 60 .TP 61 .B local_port 62 The local port number of the most recently done connection (Added in 7.29.0) 63 .TP 64 .B method 65 The http method used in the most recent HTTP request (Added in 7.72.0) 66 .TP 67 .B num_connects 68 Number of new connects made in the recent transfer. (Added in 7.12.3) 69 .TP 70 .B num_headers 71 The number of response headers in the most recent request (restarted at each 72 redirect). Note that the status line IS NOT a header. (Added in 7.73.0) 73 .TP 74 .B num_redirects 75 Number of redirects that were followed in the request. (Added in 7.12.3) 76 .TP 77 .B proxy_ssl_verify_result 78 The result of the HTTPS proxy's SSL peer certificate verification that was 79 requested. 0 means the verification was successful. (Added in 7.52.0) 80 .TP 81 .B redirect_url 82 When an HTTP request was made without --location to follow redirects (or when 83 --max-redir is met), this variable will show the actual URL a redirect 84 \fIwould\fP have gone to. (Added in 7.18.2) 85 .TP 86 .B remote_ip 87 The remote IP address of the most recently done connection - can be either 88 IPv4 or IPv6 (Added in 7.29.0) 89 .TP 90 .B remote_port 91 The remote port number of the most recently done connection (Added in 7.29.0) 92 .TP 93 .B response_code 94 The numerical response code that was found in the last transfer (formerly 95 known as "http_code"). (Added in 7.18.2) 96 .TP 97 .B scheme 98 The URL scheme (sometimes called protocol) that was effectively used (Added in 7.52.0) 99 .TP 100 .B size_download 101 The total amount of bytes that were downloaded. 102 .TP 103 .B size_header 104 The total amount of bytes of the downloaded headers. 105 .TP 106 .B size_request 107 The total amount of bytes that were sent in the HTTP request. 108 .TP 109 .B size_upload 110 The total amount of bytes that were uploaded. 111 .TP 112 .B speed_download 113 The average download speed that curl measured for the complete download. Bytes 114 per second. 115 .TP 116 .B speed_upload 117 The average upload speed that curl measured for the complete upload. Bytes per 118 second. 119 .TP 120 .B ssl_verify_result 121 The result of the SSL peer certificate verification that was requested. 0 122 means the verification was successful. (Added in 7.19.0) 123 .TP 124 .B stderr 125 From this point on, the --write-out output will be written to standard 126 error. (Added in 7.63.0) 127 .TP 128 .B stdout 129 From this point on, the --write-out output will be written to standard output. 130 This is the default, but can be used to switch back after switching to stderr. 131 (Added in 7.63.0) 132 .TP 133 .B time_appconnect 134 The time, in seconds, it took from the start until the SSL/SSH/etc 135 connect/handshake to the remote host was completed. (Added in 7.19.0) 136 .TP 137 .B time_connect 138 The time, in seconds, it took from the start until the TCP connect to the 139 remote host (or proxy) was completed. 140 .TP 141 .B time_namelookup 142 The time, in seconds, it took from the start until the name resolving was 143 completed. 144 .TP 145 .B time_pretransfer 146 The time, in seconds, it took from the start until the file transfer was just 147 about to begin. This includes all pre-transfer commands and negotiations that 148 are specific to the particular protocol(s) involved. 149 .TP 150 .B time_redirect 151 The time, in seconds, it took for all redirection steps including name lookup, 152 connect, pretransfer and transfer before the final transaction was 153 started. time_redirect shows the complete execution time for multiple 154 redirections. (Added in 7.12.3) 155 .TP 156 .B time_starttransfer 157 The time, in seconds, it took from the start until the first byte was just 158 about to be transferred. This includes time_pretransfer and also the time the 159 server needed to calculate the result. 160 .TP 161 .B time_total 162 The total time, in seconds, that the full operation lasted. 163 .TP 164 .B url_effective 165 The URL that was fetched last. This is most meaningful if you've told curl 166 to follow location: headers. 167 .RE 168 .IP 169 If this option is used several times, the last one will be used. 170
