Description of problem:
SORT behaves as if the -b and -d options are always set. Sort ignores all
leading blanks and special characters
Version-Release number of selected component (if applicable):
May 25 2005 compile date of /bin/sort
Steps to Reproduce:
1.create a file with some lines having leading space or leading _
sort order ignores leading spaces
lines with leading space or _ should sort to top unless -b and -d set
Fedora Core 4 is no longer supported, but I'd like to make sure we get this
problem solved for you. Can you try on a more recent release?
I will post this to FC 8:
I have verified on Fedora 6 and 8 the same problem:
Sort is set up to behave as if the -b and -d options are set, namely that if
a blank or a special character are in column one of a specified field, then
sort looks ahead for the first alphanumeric character and uses that to begin
the key. This is not in accordance with the man pages, and I need to be
able to sort on the field I specified for my programs to work correctly.
How do I unseclect this behavior? Specifically, I want column one to be
ordered all on it's own, and only then to look at column two, unless I ask
for -b or -d.
So far the only workaround I found is to sort each column as a separate
field such as -k 1.1,1.1 -k 1.2,1.2 etc
Now sort results in:
I see what's going on. This is documented in the info page (type 'info sort')
but not in the man page. The sort program (as all of the coreutils) are
internationalized, which means they respect LANG and LC_* variables. The
relevant part here is:
Unless otherwise specified, all comparisons use the character collating sequence
specified by the `LC_COLLATE' locale.
The traditional Unix behavior is provided by the special "C" locale. Try running
LC_COLLATE=C sort filetosort.txt
or more generally
LANG=C sort filetosort.txt
You can of course set these environment variables in your startup scripts, or
globally by editing /etc/sysconfig/i18n.
(Note that this is standard behavior on proprietary Unix too, although many
people haven't enabled internationalization.)
Reopening, because it wouldn't hurt to fix the man page.
On man page of sort you can see written:
*** WARNING *** The locale specified by the environment affects sort
order. Set LC_ALL=C to get the traditional sort order that uses native
The full documentation for sort is maintained as a Texinfo manual. If
the info and sort programs are properly installed at your site, the
should give you access to the complete manual.
This should be usually enough... anyway - doing more complex manpage will not
get accepted by upstream (as I think it is complex enough in that case) and
I think that it is not good idea to keep such patches only on RedHat side.
Problem was explained via email and in duplicate bugzilla #428679.
Closing NOTABUG for me...
