File Looper v1.0.0 - Mount iso images on Tru64

[Tru Hobbyist]

Hi all,

I just finished my first software product for Tru64 versions V5.1B-[3456] called File Looper.

File Looper allows to loop mount files like iso images on Tru64 and mount them using the cdfs filesystem type (currently the only filesystem type supported). Just choose an iso image file, attach it to a block device special file (created by File Looper) and mount it as you would mount a CD:

bash-4.3# fl -v
File looper version 1.0.0 on OSF/1
bash-4.3#
bash-4.3# fl -h
File looper syntax:

$ fl -a <dev> <file>
Attach file to device.

$ fl -d <dev>
Detach file from device.

$ fl -l
List attached files.

$ fl -h
Print help.

$ fl -v
Print version.

For more info type man fl
bash-4.3#

bash-4.3# ls -l debian-10.8.0-mips-netinst.iso
-rwxr-xr-x 1 root system 294803456 Mar 30 12:37 debian-10.8.0-mips-netinst.iso
bash-4.3#

Attach iso file to a device:

bash-4.3# fl -a /dev/loop/debianiso ./debian-10.8.0-mips-netinst.iso
bash-4.3#

Mount device:

bash-4.3# mount -t cdfs /dev/loop/debianiso /mnt/CDROM
bash-4.3#

Use mounted filesystem (access, read, copy):

bash-4.3# ls -l /mnt/CDROM

bash-4.3#

Unmount when done:

bash-4.3# umount /mnt/CDROM
bash-4.3#

List loop attachments:

bash-4.3# fl -l
/dev/loop/debianiso: /usr/users/root/debian-10.8.0-mips-netinst.iso (294803456 bytes)
bash-4.3#

Detach file from device:

bash-4.3# fl -d /dev/loop/debianiso
bash-4.3#

Verify:

bash-4.3# fl -l
INFO: No loops attached
bash-4.3#

And that's all!

Hopefully it may help sysadmins and enthusiasts alike by bringing useful functionality to these systems.

Kind regards,

Very nice! Haven't run any Tru64 in awhile.. But this looks really handy.
