I guess I'm confused.
I'm doing
<exec executable="cat"
dir=".">
<arg line="etc/jsm.properties | sed -f
tools/jsmprops_sedscriptfile > application/server/log/jsm.properties" />
</exec>
Ant DOES 'cat etc/jsm.properties" but it barfs on the rest, because
it apparently wants to interpret every token on the arg list as files:
[exec] cat: cannot open |
[exec] cat: cannot open sed
[exec] cat: cannot open -f
[exec] cat: cannot open >
This example is trivial, but more generally it is quite common on Unix
to execute a command and pipe the output through one or more programs,
and
sometimes redirect the output. In this case, we are creating a new
file from a template using some regular expression pattern matching
and replacements....
How do I uses pipes and IO re-direction in an 'exec' ???
