Package: coreutils Version: 9.1-1 Version: 9.4-3 Severity: normal Dear Maintainer,
When trying to decypher -t behaviour for #1068891,
the second empty-string semantic I tried was **(argv + optind),
but that wasn't it. But what /is/ it is -t '\0'; i.e. given
$ cat f1
row1 f1 1
urow1 f1 2
$ cat f2
row1 f2 1
urow2 f2 2
$ join <(tr '\t' '\0' < f1) <(tr '\t' '\0' < f2) -t '\0' | cat -A
row1^@f1^@1^@f2^@1$
which is great, but the manual doesn't mention this at all.
Best,
наб
