Howdy,
just going through some code of mine...

• Say you got some variables stored in a hash: name=>value and whant to replace them in a text where they are used in a make-like form: $(VARIABLE)

  foreach (keys %global_variables) {
     $content =~ s/\$\($_\)/$global_variables{$_}/g;
  }

• When you want to indent a part of text and calculated the indent already you might use:

  $content =~ s/\n/\n$indent /g;
  [download]

• Some really often used substitutions are the whitespace deletions: 1. All whitespaces: $line =~ s/\s+//g; 2. Only leading whitespaces: $line =~ s/^\s*//; 3. Only trailing whitespaces: $line =~ s/\s*$//;
• Say you got a GUI (in my case it was Gtk) and want to display some messages. In the preview window though only the first line shall be displayed, marking that more is available:

  $text =~ s/\n.*/ [more\.\.\.]/s;
  [download]

That's it for the moment. The rest of my regexp-substitutions is mostly boring ;-)

Update: Added the missing parens around VARIABLE

Regards...	Stefan
you begin bashing the string with a +42 regexp of confusion
