I have a problem with the command
join. "The default join field is the first, delimited by whitespace" (Cited from
join --help). However, there is a field containing sentences in my tab-delimted files. Thus, I want to join the two files using
-t\t (I also tried
-t "\t" which reported errors under Cygwin, but not under CentOS). Unexpectedly, the command outputted the fields in two consecutive lines. I have processed the two files with
The example of output is as follows. The 1st and 3rd lines are from file1, and the 2nd and 4th lines are from file2. The 1st and 2nd lines should appear in the same line. However, if
-t\t is used, they appear in two consecutive lines (as below); if no
-t, they appear in the same line.

I want to know whether it is a bug or I made some mistakes.
