title: Using perl instead of grep
body: <p>At work we use this construction to, for example, find out the names of all files, changed in SVN since last update and perform an <code>svn add</code> command on them: </p>
  
  <p><code>svn st | grep '^\?' | perl -pe 's/^\s*\?// | xargs -L 1 svn add'</code></p>
  
  <p>And i thought: "i wish i could use Perl one-line-script instead of <code>grep</code>". </p>
  
  <p>Is it possible to do and how if so?</p>
  
  <p><strong>P.S.:</strong> i found there is a <code>m//</code> operator in Perl. I think it should be used on ARGV variables (do not know their names in Perl - may it be the <code>$_</code> array or just <code>$1</code> -like variables?).</p>
