This is the command archivemount that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
archivemount - mounts an archive for access as a file system
SYNOPSIS
archivemount [-hVdfs] [-o options] archivepath mountpoint
DESCRIPTION
The archivemount command mounts the file tree contained in the archive archivepath on the
directory mountpoint. The archive's contents can subsequently be accessed inside
mountpoint as a file system. The umount(8) command performs the corresponding unmount
operation.
archivemount is known to work under both linux and Mac OS X (via MacFUSE).
EXAMPLE SESSION
Consider the gzipped tar archive ``files.tgz'' containing files ``file1'' and ``file2'',
and an empty directory ``mnt''.
$ ls
files.tgz mnt/
$ archivemount files.tgz mnt
$ ls mnt
file1 file2
[... Perform desired read/write operations on the archive via mnt/ ...]
$ umount mnt
[... Any changes are saved to the archive ...]
ARCHIVE FORMATS
Archive format support is provided by the libarchive(3) library. Read operations are
supported for:
· old-style tar archives,
· most variants of the POSIX ``ustar'' format,
· the POSIX ``pax interchange'' format,
· GNU-format tar archives,
· most common cpio archive formats,
· ISO9660 CD images (with or without RockRidge extensions),
· Zip archives.
Archives compressed with gzip(1), bzip2(1), or compress(1) are automatically detected and
transparently decompressed.
The following formats can be written:
· POSIX-standard ``ustar'' archives,
· POSIX ``pax interchange format'' archives,
· POSIX octet-oriented cpio archives,
· two different variants of shar archives.
Before writing, the original archive is renamed with a ``.orig'' extension appended to it.
More detail about the read/write support can be found in the libarchive(3) documentation.
