Dear coreutils :

I am a Research and Development Engineer in IT. I met a situation when I use “sort” command in Linux shell which could be a bug for the "sort" command. So I hope you read this email, thank you !

The whole command I used was ：

sort test.txt

And the result was :

20171012|3|2059517|-|8|-|20-24|2|-|2.0|2.0

20171012|3|2059517|-|82|-|25-29|2|-|13.0|12.0

20171012|3|2059517|-|8|-|-2|-2|-|71.0|64.0

20171012|3|2059517|-|82|-|30-34|0|-|2.0|1.0

The content in test.txt was:

20171012|3|2059517|-|8|-|20-24|2|-|2.0|2.0

20171012|3|2059517|-|82|-|25-29|2|-|13.0|12.0

20171012|3|2059517|-|8|-|-2|-2|-|71.0|64.0

20171012|3|2059517|-|82|-|30-34|0|-|2.0|1.0

Which means the “sort” command didn't work, because I think the correct result should be :

20171012|3|2059517|-|8|-|20-24|2|-|2.0|2.0

20171012|3|2059517|-|82|-|25-29|2|-|13.0|12.0

The version of "sort" command I use is : sort --version

I am not sure if it is a bug in "sort" command in Linux Shell or maybe it's only my problems in using it.

So I am look forward to receive your reply as soon as possible.

Thank you very much!

Sincerely yours,

Frank
