Subject: iocsh and redirection

All,

I was experimenting with redirection in the iocsh and the results were not as I expected.

I have used commands like

dbl>records.txt

in the past and they work fine.

So I created an example IOC (makeBaseApp.pl -t example) and tried:

epics> 1>test.txt
epics> dbl

and got:

Can't open "": No such file or directory.

the file test.txt was created but was empty.

Running the same test on another computer might produce

epics> 1>test.txt
epics> dbl
Can't open "ØîØð8": No such file or directory.

again test.txt is created but empty.


And interestingly on a third computer

epics> 1>test.txt
epics> dbl

will create test.txt but will output a list of records to a file named "èþ8Þ"



BTW, I was playing with this because I wanted to redirect stderr to a file. The App Developer Guide mentions epicsStdioRedirect and I was wondering what it would take to get redirection to work in any specific IOC.



Regards and thanks,
