FAR(1) UNIX Programmer's Manual FAR(1)
NAME
far - floppy archiver
SYNOPSIS
far [ -crxtu ] [ -vpwa0123 ] [ -s secsiz] [ -i ident] [ -b
bufsiz ] [ -f file] [file1...]
DESCRIPTION
_▶08◀F_▶08◀a_▶08◀r is similar to but not compatible with the tape
archiver _▶08◀t_▶08◀a_▶08◀r (1). _▶08◀F_▶08◀a_▶08◀r saves and restores files on floppy
diskettes. An argument not beginning with "-" is taken to
be a file name or a directory name. In all cases, appear-
ance of a directory name refers to the files and (recur-
sively) subdirectories of that directory. The archive can
consist of several diskettes. Before reading or writing a
diskette, _▶08◀f_▶08◀a_▶08◀r writes a prompt to the terminal and waits
for a carriage return.
Options specifying function (one must be given):
-c A new set of diskettes is created and the named
files are written on it.
-r The named files are added to the end of a previ-
ously created set.
-x The named files are extracted from the diskettes.
If the named file matches a directory whose con-
tents had been written onto the diskettes, this
directory is (recursively) extracted. The owner,
modification time, and mode are restored (if pos-
sible). If no file argument is given, the entire
content of the diskettes is extracted. Note that
if multiple entries specifying the same file are
on the diskettes, the last one overwrites all ear-
lier.
-t The names of the specified files are listed each
time they occur on the diskettes. If no file
argument is given, all of the names on the
diskettes are listed.
-u The named files are added to the diskettes if
either they are not already there or have been
modified since last put on the diskettes.
Options modifying the function:
-v Verbose. Type name of each file as it is read or
written.
-a Automatic mode. Instead of waiting for RETURN,
_▶08◀f_▶08◀a_▶08◀r waits first for drive not ready, and then for
drive ready, and assumes that this means you've
successfully inserted the next diskette.
-[0123] Normally /dev/rflop (drive 0) is used. These
options select an alternate drive: -1 selects
1
FAR(1) UNIX Programmer's Manual FAR(1)
/dev/rflop1 etc.
-s nnn A diskette is assumed to contain 1600 sectors.
This option specifies new size nnn. Higher sec-
tors are less reliable so even with 1600 sector
diskettes you may want to specify a smaller size.
-i str The character string 'str' is used to identify the
set of diskettes. If diskettes are read and this
option is given, the name on the diskette must
match 'str'.
-b nnn Gives new buffer size. This can have significant
effect on the time (real, not cpu) it takes to
read and write diskettes. Default is 12 sectors.
-p This option says to restore files to their origi-
nal modes, ignoring the present umask(2). Setuid
and sticky information will also be restored to
the super-user.
EXAMPLES
far -vcs 1200 -i "my files" foo bar
far -vx

DIAGNOSTICS
Complains about bad key characters and floppy read/write
errors.
Complains if enough memory is not available to hold the
link tables.
BUGS
There is no way to ask for the _▶08◀n-th occurrence of a file.
Floppy errors are handled ungracefully.
The u option can be slow.
The current limit on file name length is 100 characters.
