Lacking grep on Windows, search for all the occurances of the 'secret' in my xml files.

In a single file:

perl -ne "print $_ if /secret/" main.xml

As Windows does not know how to handle wildcards on the command line, we cannot supply *.xml and expect it to handle all the xml files. We help it with a small BEGIN block. $ARGV holds the name of the current file

perl -ne "BEGIN{ @ARGV = glob '*.xml'} print qq{$ARGV:$_} if /secret/"
