Hello Tru64-Unix-Managers,
I detected some strange behaviour of "pax": when the name file to be saved
exceeds
100 characters (including the path), the logging of pax truncated the name
of the file,
in fact it only shows the path, ant the filename itself desappears.
When the filename itself exceeds 100 characters, pax refuses to save this
file with
an errormessage (see pax(4) ).
I am using Tru64-unix 4.0D. Is anybody aware of this problem? Compaq patches
don't
mention this problem, so I suppose I have to create a problem report if no
one has seen
it before.
Following a script to reproduce the problem.
Greetings,

# TestPaxPath.ksh:
#
# this script shows the behaviour of pax when saving extremely long
filenames
#
# according to pax(4) the filename may be up to 100 characters
# (excluding leading path, but including "/")
#
# pax claims filenames longer than 100 chars (excluding leading path AND
"/")
# to be too long
#
# filenames exceeding 100 chars (including the path) are correctly saved as
long
# as the filename-part does not exceed 100 chars, but are truncated in the
# verbose-list (in fact only the path is showed)
