| Dear all,
I am trying to uninstall software and I get the following error:-
cp: cycle detected: /apps/SNL/SNL/Swiftnet50/lib/lb1
What does this "cp: cycle detected" relate to?
Thanks |

Is this a package you're trying to un-install?
The message comes from the cp command, not from pkgrm. IMHO it's
specific to the uninstall script of the software, and has little if
anything to do with Solaris 10.

I think this might be something to do with the link behind this file,
in that the cp command is trying to copy the file twice. Does that
sound plausable?

It's related to the 'cp' command. The "cycle detected" message means
that someone is doing a recursive copy ("cp -r"; perhaps as part of a
packaging script) and the cp command ended up visiting the same
directory more than once.
I don't _think_ that should happen unless the file system is corrupt
-- e.g., by creating a hard link to a directory. (But I'm not
certain.)

1. Don't top-post. It makes us have to scroll down to see what the heck
you're answering.
2. If you'd give the actual command you used, that would help.

Hard to say. Need more info. What does the vendor say? |

Nope:
mkdir a
ln -s . a/foo
cp -r a b
cp: cycle detected: a/foo
cp follows symlinks.
use cp -rH

Nope:
mkdir a
ln -s . a/foo
cp -r a b
cp: cycle detected: a/foo
I do this in gentoo Linux, It is ok! |
mkdir a
ln -s . a/foo
cd a
ls -l
lxwrxwrxwr ......... foo -> .
cd foo
pwd
a/foo
ls
foo
cd foo
pwd
a/foo/foo
....
It is such a thing!
