Re: Change in command line behavior between cygwin 1.3.18-1 and 1.3.19-1
Igor,
Yes, I am using textmode mounts:
---
C:\cygwin\bin on /usr/bin type system (textmode)
C:\cygwin\lib on /usr/lib type system (textmode)
C:\cygwin on / type system (textmode)
c: on /cygdrive/c type user (textmode,noumount)
d: on /cygdrive/d type user (textmode,noumount)
e: on /cygdrive/e type user (textmode,noumount)
----
If I invoke the script using a POSIX path:
---
$ /cygdrive/d/cygcheck/testscript 2>&1 | od -c
0000000
---
If I invoke using a mixed path:
---
$ d:/cygcheck/testscript/ 2>&1 | od -c
0000000 d : / c y g c h e c k / t e s t
0000020 s c r i p t [ 2 ] : s e t :
0000040 - \r : u n k n o w n o p t i
0000060 o n \n
0000063
---
However, this behavior for mixed paths is only with 1.3.19 and 1.3.20. If I
am using 1.3.17 or 1.3.18, it works (has worked for months) as I expect.
I have been using the same pdksh all these months, and so that is why I
suspect the change of behavior is in Cygwin. (I looked through the pdksh
distribution, and could not find automode.c or automode.o )
Also, please see the strace snippets I posted yesterday. Why is the file
(now) opened in text mode in one case and binary in the other?
