bug#17904: issue with split command

[jayaprakash.vambara]

Hi All,

After some investigation, I found that inspite of me giving a size 
specification as +1000, it is taking 500 as default and in this due course, it 
has deleted some files which were over 500KB.

I am able to resolve the issue now.

Thank You,
V. Jayaprakash

Thanks for the bug report.
However, TBH I don't see a problem here (... other than later file names 
possibly clashing the earlier produced "*new*" files; I reported that to the 
main coreutils list separately).

Can you please explain what you mean by "sometimes" here?
Is this related to certain files (where you could reproduce with a standalone 
"split -l 10000 file file-new" run)?

Can you please try to narrow the test case down to the file where the "aa" file 
is missing? Both split(1) and mv(1) have the --verbose option which could help 
finding the cause.

Thanks & have a nice day,
