Make curl display information on stdout after a completed transfer. The format
|
|
is a string that may contain plain text mixed with any number of
|
|
variables. The format can be specified as a literal "string", or you can have
|
|
curl read the format from a file with "@filename" and to tell curl to read the
|
|
format from stdin you write "@-".
|
|
|
|
The variables present in the output format will be substituted by the value or
|
|
text that curl thinks fit, as described below. All variables are specified as
|
|
%{variable_name} and to output a normal % you just write them as %%. You can
|
|
output a newline by using \\n, a carriage return with \\r and a tab space with
|
|
\\t.
|
|
|
|
The output will be written to standard output, but this can be switched to
|
|
standard error by using %{stderr}.
|
|
|
|
.B NOTE:
|
|
The %-symbol is a special symbol in the win32-environment, where all
|
|
occurrences of % must be doubled when using this option.
