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: o old-style tar archives, o most variants of the POSIX ``ustar'' format, o the POSIX ``pax interchange'' format, o GNU-format tar archives, o most common cpio archive formats, o ISO9660 CD images (with or without RockRidge extensions), o Zip archives. Archives compressed with gzip(1), bzip2(1), or compress(1) are automatically detected and transparently decompressed. The following formats can be written: o POSIX-standard ``ustar'' archives, o POSIX ``pax interchange format'' archives, o POSIX octet-oriented cpio archives, o 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. OPTIONS
archivemount is built upon the FUSE (Filesystem in Userspace) library, and the complete set of available options depends upon the specific FUSE implementation. Execute archivemount -h to retrieve a definitive list. general options -o opt,[opt...] mount options -h --help print help -V --version print version archivemount mount options -o readonly disable write support -o nobackup remove archive file backups FUSE mount options These options are available to linux users using standard FUSE. -d -o debug enable debug output (implies -f) -f foreground operation -s disable multi-threaded operation -o allow_other allow access to other users -o allow_root allow access to root -o nonempty allow mounts over non-empty file/dir -o default_permissions enable permission checking by kernel -o fsname=NAME set filesystem name -o subtype=NAME set filesystem type -o large_read issue large read requests (2.4 only) -o max_read=N set maximum size of read requests -o hard_remove immediate removal (don't hide files) -o use_ino let filesystem set inode numbers -o readdir_ino try to fill in d_ino in readdir -o direct_io use direct I/O -o kernel_cache cache files in kernel -o [no]auto_cache enable caching based on modification times -o umask=M set file permissions (octal) -o uid=N set file owner -o gid=N set file group -o entry_timeout=T cache timeout for names (1.0s) -o negative_timeout=T cache timeout for deleted names (0.0s) -o attr_timeout=T cache timeout for attributes (1.0s) -o ac_attr_timeout=T auto cache timeout for attributes (attr_timeout) -o intr allow requests to be interrupted -o intr_signal=NUM signal to send on interrupt (10) -o modules=M1[:M2...] names of modules to push onto filesystem stack -o max_write=N set maximum size of write requests -o max_readahead=N set maximum readahead -o async_read perform reads asynchronously (default) -o sync_read perform reads synchronously -o atomic_o_trunc enable atomic open+truncate support MacFUSE mount options These options are available to Mac users using MacFUSE. -o allow_other allow access to others besides the user who mounted the file system -o allow_recursion allow a mount point that itself resides on a MacFUSE volume (by default, such mounting is disallowed) -o allow_root allow access to root (can't be used with allow_other) -o auto_xattr handle extended attributes entirely through ._ files -o blocksize=SIZE specify block size in bytes of "storage" -o case_insensitive enable case-insensitive mode -o daemon_timeout=T timeout in seconds for kernel calls to daemon -o debug turn on debug information printing -o default_permissions let the kernel handle permission checks locally -o defer_permissions defer permission checks to file operations themselves -o direct_io use alternative (direct) path for kernel-user I/O -o extended_security turn on Mac OS X extended security (ACLs) -o fsid=FSID set the second 32-bit component of the fsid -o fsname=NAME set the file system's name -o fssubtype=NUM set the file system's fssubtype identifier -o fstypename=NAME set the file system's type name -o iosize=SIZE specify maximum I/O size in bytes -o jail_symlinks contain symbolic links within the mount -o kill_on_unmount kernel will send a signal (SIGKILL by default) to the daemon after unmount finishes -o local mark the volume as ``local'' (default is ``nonlocal'') -o negative_vncache enable vnode name caching of non-existent objects -o volname=NAME set the file system's volume name -o noalerts disable all graphical alerts (if any) in MacFUSE Core -o noappledouble ignore Apple Double (._) and .DS_Store files entirely -o noapplexattr ignore all ``com.apple.*'' extended attributes -o nobrowse mark the volume as non-browsable by the Finder -o nolocalcaches meta option equivalent to noreadahead,noubc,novncache -o noping_diskarb do not ping Disk Arbitration (pings by default) -o noreadahead disable I/O read-ahead behavior for this file system -o nosynconclose disable sync-on-close behavior (enabled by default) -o nosyncwrites disable synchronous-writes behavior (dangerous) -o noubc disable the unified buffer cache for this file system -o novncache disable the vnode name cache for this file system -o hard_remove immediate removal (don't hide files) -o use_ino let filesystem set inode numbers -o readdir_ino try to fill in d_ino in readdir -o direct_io use direct I/O -o kernel_cache cache files in kernel -o [no]auto_cache enable caching based on modification times -o umask=M set file permissions (octal) -o uid=N set file owner -o gid=N set file group -o entry_timeout=T cache timeout for names (1.0s) -o negative_timeout=T cache timeout for deleted names (0.0s) -o attr_timeout=T cache timeout for attributes (1.0s) -o ac_attr_timeout=T auto cache timeout for attributes (attr_timeout) -o intr allow requests to be interrupted -o intr_signal=NUM signal to send on interrupt (30) -o modules=M1[:M2...] names of modules to push onto filesystem stack -o max_write=N set maximum size of write requests -o max_readahead=N set maximum readahead -o async_read perform reads asynchronously (default) -o sync_read perform reads synchronously Module options [subdir] -o subdir=DIR prepend this directory to all paths (mandatory) -o [no]rellinks transform absolute symlinks to relative [iconv] -o from_code=CHARSET original encoding of file names (default: UTF-8) -o to_code=CHARSET new encoding of the file names (default: ISO-8859-2) LICENSE
