Re: sort (coreutils) 4.5.3 |

On my Red Hat Linux 9 system the LANG variable is set to
"en_US.iso885915". When using the Perl sort function I get
the correct results but when using the sort command I have to
change the LANG setting to get correct results. To get the sort
command to work I entered the following:
LANG=C sort inputfile.txt
Since the Perl sort function works correctly, is it possible that
the problem could be in the way the sort command interacts
with the LANG environment instead of the LANG environment
itself ? With Perl I did not have to change LANG; I used the
following Perl command to determine what LANG Perl was using:
print $ENV{LANG};
I am including two small files ( 10 lines each);
1. inputfile.txt - the unsorted input file
2. rhlinux_sort.txt - the output file from the Red Hat sort command
