Mailutils info

From Mailutils

Jump to: navigation, search

The mailutils info command displays information about GNU Mailutils compile-time configuration. In normal form its output lists a single configuration flag per line, e.g.:

 $ mailutils info
 VERSION=2.99.99
 SYSCONFDIR=/etc
 MAILSPOOLDIR=/var/mail/
 SCHEME=mbox
 LOG_FACILITY=mail
 IPV6
 USE_LIBPAM
 HAVE_LIBLTDL
 WITH_GDBM
 WITH_GNUTLS
 WITH_GSASL
 ...

A configuration flag can consist either of a single word, indicating that a particular capability has been enabled at compile time, or of a keyword/value pair delimited by an equal sign, which indicates a particular value used by default for that feature. For example, IPV6 means that Mailutils was compiled with support for IPv6, whereas SYSCONFDIR=/etc means that the default place for configuration files is in /etc directory.

Such short output is convenient for using mailutils info in scripts to decide whether it is possible to use a given feature. To assist human users, the --verbose (-v) option is provided. It prints a short description next to each flag:

 $ mailutils info --verbose
 VERSION=2.99.98           - Version of this package
 SYSCONFDIR=/etc           - System configuration directory
