In theory, simply replace the Perl script with one which prompts you for each substitution. In practice, for usability reasons, you would probably want to use the search and replace features of an editor, and simply feed the editor with a simple script. That way, you get undo, a nice way for the user to see the wider context of each change, and of course, the ability to make unrelated edits when you see something which needs fixing, etc. I personally recommend Emacs, but whatever editor you, or your users, are familiar with should do (unless it's too GUIey for its own good ...).

edquota

EDQUOTA(8)						      System Manager's Manual							EDQUOTA(8)

NAME

       edquota - edit user quotas

SYNOPSIS

       edquota [ -p proto-user ] users...

DESCRIPTION

       Edquota	is  a  quota  editor.	One or more users may be specified on the command line.  For each user a temporary file is created with an
       ASCII representation of the current disc quotas for that user and an editor is then invoked on the file.  The quotas may then be  modified,
       new  quotas  added,  etc.   Upon  leaving  the  editor, edquota reads the temporary file and modifies the binary quota files to reflect the
       changes made.

       If the -p option is specified, edquota will duplicate the quotas of the prototypical user specified for each user specified.  This  is  the
       normal mechanism used to initialize quotas for groups of users.

       The editor invoked is vi(1) unless the environment variable EDITOR specifies otherwise.

       Only the super-user may edit quotas.

FILES

       quotas	      at the root of each file system with quotas
       /etc/fstab     to find file system names and locations

SEE ALSO

       quota(1), quota(2), quotacheck(8), quotaon(8), repquota(8)

DIAGNOSTICS

       Various messages about inaccessible files; self-explanatory.

BUGS

       The format of the temporary file is inscrutable.
