If LANG is set then programs are required to follow the collating
rules of the operating system. I am just going to jump in with this
as the likely problem. Please report back. You can read about the
details here.
What does the output of 'locale' say?
LANG=en_US.iso885915
LC_CTYPE="en_US.iso885915"
LC_NUMERIC="en_US.iso885915"
LC_TIME="en_US.iso885915"
LC_COLLATE="en_US.iso885915"
LC_MONETARY="en_US.iso885915"
LC_MESSAGES="en_US.iso885915"
LC_PAPER="en_US.iso885915"
LC_NAME="en_US.iso885915"
LC_ADDRESS="en_US.iso885915"
LC_TELEPHONE="en_US.iso885915"
LC_MEASUREMENT="en_US.iso885915"
LC_IDENTIFICATION="en_US.iso885915"
LC_ALL=
locale
Try unsetting LANG, or setting LC_ALL to POSIX and try the test again.
export LC_ALL=POSIX
That solves the problem. (either LANG= or LC_ALL=POSIX)
Is it safe to permanently set that to POSIX?
I just d/l'd & compiled coreutils 4.5.3 from gnu.org...
it also has the same problem output.
Also, if I SORT the files, then I only get 2 lines output from join!
(they were already sorted in some sense, but not by sort)
Then, if I export LC_ALL=POSIX, and run join again, I only get 1 line of
output!
(re-sorting fixes that)
I'm a bit confused as I would have assumed that if both files were sorted
in the same manner, then join shouldn't have any reason to have trouble
with them.
BTW, can someone let RedHat know about this? (Last time I emailed them
about a bug they were somewhat hostile as I don't have paid support.)
Thank you,
Barry
