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

[si]

Hi Erin,

It's do-able, just a little painful, but I think Martin was on the right track.

For example, here's what I do to call the Subversion svnadmin program
to dump a repository, redirecting stdout. Works on Windows and Linux:
...
    <target name="init-shell">
        <if test="${platform::is-win32()}">
            <property name="shell"        value="CMD" />
            <property name="shell-switch" value="/S /C " />
        </if>
        <if test="${platform::is-unix()}">
            <property name="shell"        value="sh" />
            <property name="shell-switch" value="-c " />
        </if>
    </target>
...
    <target name="svnadmin-dump">
...
        <exec program="${shell}" failonerror="${failonerror}"
resultproperty="dump-result">
            <arg line='${shell-switch}""${svnadmin}" dump
"${path::combine(svn-root,repo)}" &gt; "${dump-file}" ${arg-revision}
${arg-incremental} ${arg-deltas}"'/>
        </exec>
...
    </target>

Hope that helps.

peace
si
