Hello,
fileutils version: 4.1
cc: gcc
os: solaris 7
I made a copy of my files with the '-a -v -u' flags. I then re-ran cp
with the same flags on the same files (none of which had changed and it
updated a significant proportion of them.
As a simple example:
# ls -l .tcshrc*
-rw-r--r-- 1 stewart 340 Mar 11 13:05 .tcshrc
# cp -a -v -u .tcshrc .tcshrc.cp
`.tcshrc' -> `.tcshrc.cp'
# ls -l .tcshrc*
-rw-r--r-- 1 stewart 340 Mar 11 13:05 .tcshrc
-rw-r--r-- 1 stewart 340 Mar 11 13:05 .tcshrc.cp
# cp -a -v -u .tcshrc .tcshrc.cp
`.tcshrc' -> `.tcshrc.cp'
# touch .tcshrc.cp
# cp -a -v -u .tcshrc .tcshrc.cp
#
This behaviour appears to be random but happens more often in more
recent files. On older files, the following:
# ls -l .signature*
-rw-r--r-- 1 stewart 322 Oct 25 10:33 .signature
# cp -a -v -u .signature .signature.cp
`.signature' -> `.signature.cp'
# ls -l .signature*
-rw-r--r-- 1 stewart 322 Oct 25 10:33 .signature
-rw-r--r-- 1 stewart 322 Oct 25 10:33 .signature.cp
# cp -a -v -u .signature .signature.cp
#
Thanks,
- Stewart
