I have a problem where tar is somehow creating duplicate filenames when tarring a directory. Doing an ls on the directory does not show any duplicate filenames, yet when the directory is tarred, you can see that there are duplicates:
Code:
bash-2.03# pwd
/var/log/cricket
bash-2.03# ls -1 | sort | uniq -d
bash-2.03# tar cvf /tmp/ctar.tar . >/dev/null
bash-2.03# tar tvf /tmp/ctar.tar | awk '{ print $NF }' | sort | uniq -d
./cricket24b.10
./cricket24b.79
bash-2.03# tar tvf /tmp/ctar.tar | grep ./cricket24b.10
-rw-r--r-- 0/1 13328 Mar 13 01:42 2007 ./cricket24b.100
-rw-r--r-- 0/1 13330 Mar 14 09:42 2007 ./cricket24b.10
-rw-r--r-- 0/1 13331 Mar 14 09:57 2007 ./cricket24b.10
bash-2.03# ls -l /var/log/cricket/cricket24b.10
-rw-r--r-- 1 root other 13331 Mar 14 09:57 /var/log/cricket/cricket24b.10
bash-2.03# date
Wed Mar 14 12:30:11 EDT 2007
There are no hard links, at least not for this specific file
-rw-r--r-- 1 root other 13331 Mar 14 09:57 /var/log/cricket/cricket24b.10
The link count=1
Are you really suie we are dealing with duplicate file names?
It could be that 1 file actually has the name as you see it. The other one could contain non printable characters in its name, which makes it look as if the file has the same name.
You could try the command:
Code:
ls -l /var/log/cricket | grep "Mar 14 09:"
and see if it looks like duplicate names pop up.
If this is the case you can try the command:
Code:
ls -lb /var/log/cricket | grep "Mar 14 09:"
which should show the file names actually differ.
This is all assuming the time stamps of the files haven't changed.
I would like to confirm my file.tar is been tar-ed correctly before I remove them. But I have very limited disc space to untar it.
Can I just do the listing instead of actual extract it? Can I say confirm folder integrity if the listing is sucessful without problem?
