The problem with this code snippet is that if there are no occurances of
${lookingFor} in the file ${output}, then instead of an empty file being
written out to ${basedir}/temp.txt, instead the literal string
"${contains.errors}" gets written out to that file. That's because the
property contains.errors has not been set.
An even better approach would be to use the copy command, like so:
<copy file="${output}" tofile="${basedir}/temp.txt">
<filterchain>
<linecontains>
<contains value="differ}"/>
</linecontains>
</filterchain>
</copy>
This way if there are no occurances of ${lookingFor} in file ${output}, then an
empty file gets written out to ${basedir}/temp.txt

oh you are looking to do something like :
cat log.txt | grep "a string" | wc -l
<loadfile srcfile="${output}" property="contains.errors">
<filterchain>
<linecontains>
<contains value="${lookingFor}"/>
</linecontains>
</filterchain>
</loadfile>
<echo file="${basedir}/temp.txt" message="${contains.errors}"/>
So now you have the lines from the ${output} which contain ${lookingFor}
in a temp file temp.txt
After this, you could use the example Matt gave to find out the number
of lines in temp.txt
Hope this helps.
