Summary: [xdvi] xdvizilla doesn't work on Solaris

Initial Comment:
On Solaris, the file command doesn't identify dvi
files, so xdvizilla terminates with an error message
instead of calling xdvi:

% file foobar.dvi
foobar.dvi:  data

Adding tag [xdvi] since it has been fixed in xdvik's xdvizilla.

Great, that's even better; we don't need a shell function in
that case and can just use file -m on all platforms.

Unfortunately, Solaris (Solaris 9 in my case) doesn't
recognize head -c.  Here's an alternative:

echo '0<tab>string<tab>\367\002<tab>TeX DVI file' > tmpmagic
file -m tmpmagic thefile

--Paul

Could we maybe use an extra check for DVI files on Solaris?
E.g.:

get_filetype()
{
    f="$1"
    have_solaris=`uname -a | grep -i solaris` ### FIXME:
Check actual output on solaris ...
    if [ "$have_solaris"xxx == "xxx" ]
    then
	ret=`file "$f"`
    else
	# Solaris' file command fails to identify DVI files (bug
#1508963),
	# so here's an extra check for these:
	magic=`head -c 2 "$f" | od -x | head -n 1 | awk '{print $2}'`
	### FIXME: Can the above command be simplified? Is the
output of "od" endian-dependent?
	if [ "$magic" == "02f7" ] 
	then
	    ret="TeX DVI file"
	else
	    ret=`file "$f"`
	fi
    fi
    echo "$ret"
}

and then instead of:

FILETYPE=`file "$FILE"`

use:

FILETYPE=`get_filetype "$FILE"`
