Hello,
I wonder if the fuser utility coming with Cygwin is returning an error code that isn't in line with the IEEE specifaction. What is happening:
---
somogyib@demuc12306 ~
$ fuser /cygdrive/f/Bazsi/cygwin/bin/bash; echo $?
/cygdrive/f/Bazsi/cygwin/bin/bash: 2708e
0
somogyib@demuc12306 ~
$ fuser /cygdrive/f/Bazsi/cygwin/bin/awk; echo $?
1
---
So, the "bash" file is locked by one process and "awk" is by zero.
For both scenarios FreeBSD returns 0 which I assume to be correct. The IEEE standard says fuser should return non-zero value only when an error occured.
---
www.unix.org\single_unix_specification\susv3\utilities\fuser.html
EXIT STATUS
The following exit values shall be returned:
0
Successful completion.
>0
An error occurred.
---
A file being locked by one, two or ZERO process is all positive scenario so fuser should return 0. What's you opinion? Can this be fixed?
Cheers,
Balazs
