Description Marcus Moeller 2015-12-18 07:32:09 EST

Description of problem:
On one machine we have got coreutils 8.22-15 and on another machine we have got 8.23-10.

We are executing a sort on a list of checksums on both machines. The input data is the same, but the result is different when it contains two or more files with the same checksum.

I have attached two files for both versions. The output has been created with the following command:

find . -type f -exec md5sum {} \; | sort

Comment 3 Pádraig Brady 2015-12-18 08:40:04 EST

The two attachments are different due to different inputs,
rather than different sorting order:

--- 8.22.txt
+++ 8.23.txt
+be61b01fd8631d488c5a17d8c4b00146  ./.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi
-c6ede12325019d608f28dee4165fa814  ./.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi


BTW your checksum will proceed faster by minimizing the number of md5sum processes by using '+' in your command rather than '\;'

Thanks for taking care and sorry for the noise.
