Cannot open txt file in UNIX using cat utility
Hi,
I am not being able to open txt files with 'cat'. One thing to mention is, the filenames start with #. I guess one can have a unix filename that starts with a special/wildcard character. I have filenames starting with @ [like @filename] and they are opening perfectly with cat.

mkmanifest
MKMANIFEST(1) General Commands Manual MKMANIFEST(1)
NAME
mkmanifest - create a shell script to restore Unix filenames
SYNOPSIS
mkmanifest [ files ]
DESCRIPTION
Mkmanifest creates a shell script that will aid in the restoration of Unix filenames that got clobbered by the MSDOS filename restrictions.
MSDOS filenames are restricted to 8 character names, 3 character extensions, upper case only, no device names, and no illegal characters.
The mkmanifest program is compatible with the methods used in pcomm, arc, and mtools to change perfectly good Unix filenames to fit the
MSDOS restrictions.
EXAMPLE
I want to copy the following Unix files to a MSDOS diskette (using the mcopy command).
very_long_name
2.many.dots
illegal:
good.c
prn.dev
Capital
Mcopy will convert the names to:
very_lon
2xmany.dot
illegalx
good.c
xprn.dev
capital
The command:
mkmanifest very_long_name 2.many.dots illegal: good.c prn.dev Capital > manifest
would produce the following:
mv very_lon very_long_name
mv 2xmany.dot 2.many.dots
mv illegalx illegal:
mv xprn.dev prn.dev
mv capital Capital
Notice that "good.c" did not require any conversion, so it did not appear in the output.
Suppose I've copied these files from the diskette to another Unix system, and I now want the files back to their original names. If the
file "manifest" (the output captured above) was sent along with those files, it could be used to convert the filenames.
