@defmodule[file/tar]{The @racketmodname[file/tar] library provides
|
|
utilities to create archive files in USTAR format, like the archive
|
|
that the Unix utility @exec{pax} generates. The USTAR format imposes
|
|
limits on path lengths. The resulting archives contain only
|
|
directories and files (symbolic links are followed), and owner
|
|
information is not preserved; the owner that is stored in the archive
|
|
is always ``root.''}
|
|
|

@defproc[(tar [tar-file path-string?][path path-string?] ...)
|
|
exact-nonnegative-integer?]{
|
|
|
|
Creates @racket[tar-file], which holds the complete content of all
|
|
@racket[path]s. The given @racket[path]s are all expected to be
|
|
relative path names of existing directories and files (i.e., relative
|
|
to the current directory). If a nested path is provided as a
|
|
@racket[path], its ancestor directories are also added to the
|
|
resulting tar file, up to the current directory (using
|
|
@racket[pathlist-closure]).}

exact-nonnegative-integer?]{
|
|
|
|
Packages each of the given @racket[paths] in a @exec{tar} format
|
|
archive that is written directly to the @racket[out]. The specified
|
|
@racket[paths] are included as-is; if a directory is specified, its
|
|
content is not automatically added, and nested directories are added
|
|
without parent directories.}
