Hello!
In sort man page nothing told about working sort --check with '--key'
option. IMHO this behaviour is strange:
This case is succeeded:
$ echo -e '1\t2\n1\t1' | LC_ALL=C sort --key=1b,1 --check --stable
--field-separator=$'\t'
But this (without option '--stable') is failed:
$ echo -e '1\t2\n1\t1' | LC_ALL=C sort --key=1b,1 --check
--field-separator=$'\t'
sort: -:2: disorder: 1 1
It seems to me both of situation is equal with relation of line key, why
does the output is different?
Sincerely yours, Alexander K
