Re: [NAnt-users] Can't use pipe (|) within exec

as far as I know piping (or redirection) doesnt work from .net at all. I seem to remember the Process class not being able to handle it a long time ago.

Actually, I'm not sure that will work either.

I think you have to do this:

<exec program="p4.exe" commandline="label -o DevTemplate | sed -e "s/DevTemplate/dev01/g" | p4.exe label -i" />

Your xml code has an illegal use of quotes.

Try this:

<exec program="p4.exe" commandline='label -o DevTemplate | sed -e

"s/DevTemplate/dev01/g" | p4.exe label -I' />

Thanks,

Melissa

Hi,

When I try to use a pipe or redirecting arrow in the exec task, I get a

failure saying the program I executed has the wrong number of arguments.

Here's what it looks like within my script:

<exec program="p4.exe" commandline="label -o DevTemplate | sed

-e "s/DevTemplate/dev01/g" | p4.exe label -i" />

I get the same failure no matter what program I am using; it isn't

unique to my "p4.exe" program. If I type the following into a command

prompt, everything works just fine:

p4 label -o DevTemplate | sed -e "s/DevTemplate/dev01/g" | p4

label -i

So, how can I translate the above line into NAnt without resorting to a

batch file?

Thank you,

Erin
