Hello,
when gawk is called outside the cygwin runtime, i.e. called from a command
prompt under Windows, and it's input is redirected to a pipe with an output of
a non-cygwin command, e.g. the Windows DIR, it does not recognize this.
As a result input conversion from "\r\n" to "\n" isn't performed an
additional "\r"s are printed.
Example:
C:\TEMP\foo>dir
Datenträger in Laufwerk C: ist System
Volumeseriennummer: FCD8-BBF6
Verzeichnis von C:\TEMP\foo
12.04.2002 12:21 <DIR> .
12.04.2002 12:21 <DIR> ..
12.04.2002 12:20 0 bar_1
12.04.2002 12:20 0 bar_2
2 Datei(en) 0 Bytes
2 Verzeichnis(se), 3.320.262.656 Bytes frei
C:\TEMP\foo>dir /b | gawk '{print $0 $0}'
bar_1
bar_2
==> should print bar_1bar_1 and bar_2bar_2.
==> In fact bar_1\rbar_1 and bar_2\rbar_2 are printed.
==> (Can be seen with redirection and a hex editor)
C:\TEMP\foo>ls -1 | gawk '{print $0 $0}'
bar_1bar_1
bar_2bar_2
C:\TEMP\foo>bash -c "ls -1 | gawk '{print $0 $0}'"
bar_1bar_1
bar_2bar_2
==> These outputs are correct.
Best regards
Markus Brandt
