that's weird.

the backtick is nothing more than the output from the commands executed in between them.

when i run:

today=`date +%m%d%y`
echo $today

i get '021306'.

that being the case... i changed it and did...

today="`date +%m%d%y`.tar"
tar -cvf $today ./ # tarring just the current dir tree to see if it works

...and everything worked fine... and tarred the files/dirs into 021306.tar

i don't know what kind of system you're using, but i've tried this on windows (Cygwin bash), Linux (Red Hat bash), and AIX (ksh) and got the same results.

don't know why it would be a hidden file. sorry... i wish i had more insight.

mkfs.bfs

MKFS.BFS(8)						Linux System Administrator's Manual					       MKFS.BFS(8)

NAME

       mkfs.bfs - make an SCO bfs filesystem

SYNOPSIS

       mkfs.bfs [-N nr-of-inodes] [-V volume-name] [-F fsname] device [size-in-blocks]

DESCRIPTION

       mkfs.bfs creates an SCO bfs file-system on a block device (usually a disk partition or a file accessed via the loop device).

       The  size-in-blocks  parameter  is  the	desired size of the file system, in blocks.  If nothing is specified, the entire partition will be
       used.

OPTIONS

       -N     Specify the desired number of inodes (at most 512).  If nothing is specified some default number	in  the  range	48-512	is  picked
	      depending on the size of the partition.

       -V volume-label
	      Specify the volume label. I have no idea if/where this is used.

       -F fsname
	      Specify the fsname. I have no idea if/where this is used.

       -v     Be verbose.

EXIT CODES

       The exit code returned by mkfs.bfs is 0 when all went well, and 1 when something went wrong.

SEE ALSO

       mkfs(8).

AVAILABILITY

       The mkfs.bfs command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
