Subject RE: Newbie question about exec/chown
Date Mon, 22 Apr 2002 22:51:04 GMT
I think it may be very slow because you are in fact executing "chown -R
user:web" for every single file under the ${dir} directory. Since the -R
switch to chown already recurses into sub-dirs, what you need is more
something like:

<exec executable="sh" dir="${dir}>
  <arg line="chown -R user:web" />
</exec>

Or instead, modify your existing <apply> as follows:

      <apply executable="chown" dir="${dir}" type="both" parallel="true">
           <arg value="-R"/>
           <arg value="user:web"/>
           <fileset dir="${dir}" includes="*" />
      </apply>

Let me know why one works best. Regards, --DD

That seemed to work. Here is the end result:
      <apply executable="chown" dir="${dir}" type="both">
           <arg value="-R"/>
           <arg value="user:web"/>
           <fileset dir="${dir}"/>
      </apply>


It is quite a bit slower than the shell command itself (using bash), but
it works.

Command line expansion is performed by the shell, not the unix command
themselves. So execute sh or bash or csh or whatever other shell, adding
chown in front of your arg line.

Or use <apply> with a <fileset>. --DD

Subject: Newbie question about exec/chown

All,
I am trying to write an exec task in UNIX to chown a directory and files
(as
well as the subdirectories). The task command I am using is:

      <exec dir="${dir}" executable="chown" os="SunOS">
           <arg line="-R user:web ${dir}/*"/>
      </exec>

This returns:
     [exec] chown: /data/netscape/docs/target/*: No such file or
directory
     [exec] Result: 1

This seems to come out well when I <echo> the entire task command.

Any thoughts?
