how to "echo" exec command
how do I "echo" or display the full command exec is about to run? In my
example I should see
[exec] VBoxManage controlvm vm poweroff
but nothing is shown.
ant version=1.7 os = fedora 10 shell=bash, jdk=1.5.8
<target name="vbox" depends="-init-run">
<exec executable="VBoxManage" failifexecutionfails="false">
<arg line="controlvm ${vbox.vmname} poweroff"/>
</exec>
....
vbox:
[exec]
[exec] VirtualBox Command Line Management Interface Version 2.1.4

Re: how to "echo" exec command
Posted by David Weintraub <qa...@gmail.com>.
I take it you're a Windows person. The "echo on" and "echo off"
parameters are really part of the CMD.EXE "DOS" shell on Windows. It's
not a feature of Ant or of the OS.
When you use the <exec> command, you are running the command without the shell.
What you can do, if you really want to do this is run the command
through "cmd.exe" instead of doing it directly. That way, you get the
full power of the shell. Of course, it is slower, but it might get
what you want.
Something like this:
<exec executable="cmd.exe"
failifexecutionfails="false">
<arg line="/C VBoxManage controlvm {vbox.vmname} poweroff"/>
</exec>
<target name="vbox" depends="-init-run">
> <exec executable="VBoxManage" failifexecutionfails="false">
> <arg line="controlvm ${vbox.vmname} poweroff"/>
> </exec>

Re: AW: how to "echo" exec command
Posted by viet nguyen <vi...@gmail.com>.
Thanks for getting back to me.
I'm aware of -verbose and -debug but they generate too much much
information. I'm looking for something simple and analogous to @ in DOS
batch file.
I guess I can write an exec macrodef and print the command as Martin
suggested.

RE: how to "echo" exec command
Posted by Martin Gainty <mg...@hotmail.com>.
you can
<echo>put your entire command line here</echo>
or redirect exec stdout with the ant exec task 'output' attribute e.g.
<exec executable="VBoxManage" failifexecutionfails="false" output="Somefile.txt">
<arg line="controlvm ${vbox.vmname} poweroff"/>
</exec>
and view the contents of 'Somefile.txt' after execution
