} The below script will change all instances of the string "blue apple"
} to "red pear" in files under the directory /home/zzz.  This may or may
} not help you write your own script.  Make sure you backup your files and
} test your script on a bogus directory first!

Be aware that it will also mangle permissions and will fail for filenames
with whitespace in them.  This kind of thing is relatively straightforward
with perl5; if you'd prefer to stick to "stock" tools, an ed script would
probably be more advisable if you care about these issues.  

} #!/bin/sh
} for file in `find /home/zzz`
} do
}         if [ -f $file ]
}         then
}                 sed 's/blue apple/red pear/g' $file > /tmp/$$
}                 mv /tmp/$$ $file
}         fi
} done
