.SH OPTIONS
.IP "\fB\-arch \fIarchive\fR" 14
Name of logical archive. If none is specified, the environment
variable JARCHIVE is used, if defined, else the default archive
is used.
.IP "\fB\-server \fIhostname\fR" 14
Specifies host where Jaquith server is running. Defaults
to the environment variable JSERVER.
.IP "\fB\-port \fIport\fR" 14
Specifies port number where Jaquith server is running. Defaults
to the environment variable JPORT.
.IP "\fB\-range \fIdate1\fR,\fIdate2\fR" 14
List files with date in specified range.
.IP "\fB\-owner \fIname\fR" 14
List only files with specified owner name.
.IP "\fB\-group \fIname\fR" 14
List only files with specified group name.
.IP "\fB\-abs \fIregexp\fR" 14
List files which match \fIregexp\fR in their abstract lines.
.IP "\fB\-asof \fIdate\fR
List version which was current as of specified date. Equivalent to:
\-range(1-jan-1970,\fIdate\fR)
.IP "\fB\-since \fIdate\fR
List versions between \fIdate\fR and present date. Equivalent to:
\-range(\fIdate\fR,\fIpresent-date\fR)
.IP "\fB\-first \fIn\fR
List from the nth version in the date range.
.IP "\fB\-last\fR
List to the nth version in the date range.
.IP "\fB\-all\fR
List all the versions in the archive. Equivalent to: -first 1 -last -1
.IP "\fB\-moddate\fR
Use the file's modification date, not its archive date
for all date comparisons.
.IP "\fB\-l\fR" 14
Display using long format (see below).
.IP "\fB\-i\fR" 14
Display buffer number where file lives, volume id where buffer lives,
and position on volume of buffer.
.IP "\fB\-u\fR" 14
Display archive date instead of last-modification date (with -l option).
.IP "\fB\-a\fR" 14
Display abstract.
.IP "\fB\-s\fR" 14
Display file size in 1024 byte units.
.IP "\fB\-g\fR" 14
Display group name.
.IP "\fB\-d\fR" 14
Display directory name only.
.IP "\fB\-R\fR" 14
Display directory tree recursively.
.IP "\fB\-raw\fR" 14
Display output in raw mode. This feature is undocumented,
(you are NOT presently reading this) and is subject to change/removal.

.SH DESCRIPTION
.PP
\fBJls\fP provides a simple directory listing mechanism
for an archive tape system controlled by the Jaquith program.
.PP
The primary argument \fIfilelist\fR is a file expression
which specifies the files to be listed. Shell-like globbing
is supported. '*' matches any number of characters. '?'
matches a single character. Additionally, curly braces can
be used to enclose alternatives. For example foo.{bak,?}
matches foo.bak, foo.c and foo.h.
.PP
Note that any metacharacters which are
not protected with a backslash or quotes will be expanded by the
shell, not by the Jaquith system.
.PP
The default action is to list the simple filenames of the
most recent versions of matching filenames.
The set of files listed can be controlled by the use of
one or more options. The options are all logically ANDed
together; only files matching all criteria are listed.
.PP
The -range, -first and -last options work together to specify
a subset of the archived versions. First, the date range is
applied, resulting in a list of candidates numbered logically
from 1 to \fIn\fR. Then the first and last options are applied
to this list. First and last can be positive and retrieve the
specified filenames from restricted list, or they can be negative
in which case they count from the end of the list. Thus, the
most recent version of a file can be retrieved with 'first -1
last -1' without having to know how many versions currently exist.
.PP
\fIdate\fR is of the form \fIDateSpec[:TimeSpec]\fR. \fITimeSpec\fR
is of the form [hh[:mm[:ss]]], and \fIDateSpec\fR is of the form
dd\(hymonth[\(hyyyyy]. Month is the first 3 letters of the month;
all others are numbers. The '/' character is a substitute
for '-' and '.' may be used instead of ':'.
.PP
By default jls simply lists the matching filenames, 1 per line.
In long form jls generates:
.IP
\fImode ownerID size date filename\fR
.PP
With the \fB-i\fR option the "inode" information is included:
.IP
\fItBufId volId filemark mode ownerID size date filename\fR
.PP
\fIdate\fR is the archive date if the \fI-u\fR
option is given, else it's the file's last modification date.
.SH BUGS
The option flags have little relation to the standard ls options.
.PP
No multicolumn formatting is provided.
.PP
A file which matches more than one regular expression will be
listed multiple times.
.PP
Only one archive can be specified at a time.
.PP
Unlike the shell, the Jaquith globbing characters '*' and '?' match
a '.' in the first position.
