Resume Wikipedia de Linux

GNU/Linux ou Linux est un système d’exploitation associant des éléments essentiels du projet GNU et le noyau Linux.
Fondé en 1984 par Richard Stallman, le système d’exploitation GNU resta jusqu’en 1991 au stade expérimental car son noyau Hurd était toujours en développement. Cependant, Linus Torvalds créa indépendamment le noyau Linux qui résolut le problème en remplaçant Hurd.
Néanmoins, cette mise en relation des deux projets engendra une controverse toujours d’actualité autour du nom du système associant les deux éléments, certains, dont le grand public, appelant le système simplement Linux, et d’autres, dont Richard Stallman, défendant le nom combiné GNU/Linux.

RUN-MAILCAP(1) Run Mailcap Programs RUN-MAILCAP(1)


run-mailcap, view, see, edit, compose, print – execute programs via
entries in the mailcap file


run-mailcap –action=ACTION [–option[=value]] [MIME-TYPE:[ENCOD‐
ING:]]FILE […]

The see, edit, compose and print versions are just aliases that default
to the view, edit, compose, and print actions (respectively).


run-mailcap (or any of its aliases) will use the given action to
process each mime-type/file in turn. Each file is specified as its
mime-type, its encoding (e.g. compression), and filename together, sep‐
arated by colons. If the mime-type is omitted, an attempt to determine
the type is made by trying to match the file’s extension with those in
the mime.types files. If no mime-type is found, a last attempt will be
done by running the file command, if available. If the encoding is
omitted, it will also be determined from the file’s extensions. Cur‐
rently supported encodings are gzip (.gz), bzip (.bz), bzip2 (.bz2),
and compress (.Z). A filename of “-” can be used to mean “standard
input”, but then a mime-type must be specified.

Both the user’s files (~/.mailcap; ~/.mime.types) and the system files
(/etc/mailcap; /etc/mime.types) are searched in turn for information.

All options are in the form —=.

Performs the specified action on the files. Valid actions are
view, cat (uses only “copiousoutput” rules and sends output to
STDOUT) , compose, composetyped, edit and print. If no action
is specified, the action will be determined by how the program
was called.

Turns on extra information to find out what is happening.

Ignores any “copiousoutput” directive and sends output to STD‐

Displays the found command without actually executing it.

A temporary copy of the file is opened if the file name matches the
Perl regular expresssion “[^[:alnum:],.:/@%^+=_-]”, in order to protect
from the injection of shell commands, and to make sure that the name
can always be displayed in the current locale. In addition, the file
is opened using its absolute path to prevent the injection of command-
line arguments, for instance using file names starting with dashes.
