RFC2368 defines mailto: URIs. xdg-email limits support to, cc, subject and body fields in mailto-uri, all other fields are silently ignored. address(es) must follow the syntax of RFC822. Multiple addresses may be provided as separate arguments. All information provided on the command line is used to prefill corresponding fields in the user's e-mail composer. The user will have the opportunity to change any of this information before actually sending the e-mail. xdg-email is for use inside a desktop session only. It is not recommended to use xdg-email as root. Options --utf8 Indicates that all command line options that follow are in utf8. Without this option, command line options are expected to be encoded according to locale. If the locale already specifies utf8 this option has no effect. This option does not affect mailto URIs that are passed on the command line. --cc address Specify a recipient to be copied on the e-mail. --bcc address Specify a recipient to be blindly copied on the e-mail. --subject text Specify a subject for the e-mail. --body text Specify a body for the e-mail. Since the user will be able to make changes before actually sending the e-mail, this can be used to provide the user with a template for the e-mail. text may contain linebreaks. --attach file Specify an attachment for the e-mail. file must point to an existing file. Some e-mail applications require the file to remain present after xdg-email returns. --help Show command synopsis. --manual Show this manual page. --version Show the xdg-utils version information. Environment Variables xdg-email honours the following environment variables: XDG_UTILS_DEBUG_LEVEL Setting this environment variable to a non-zero numerical value makes xdg-email do more verbose reporting on stderr. Setting a higher value increases the verbosity. Exit Codes An exit code of 0 indicates success while a non-zero exit code indicates failure. The following failure codes can be returned: 1 Error in command line syntax. 2 One of the files passed on the command line did not exist. 3 A required tool could not be found. 4 The action failed. 5 No permission to read one of the files passed on the command line.
