It will only do this once though, i.e. not globallythroughout the file.  It writes a backup file and then does an os.rename()dance for atomicity.Usage: fixnotices.py [options] [filenames]Options:    -h / --help        Print this message and exit    --oldnotice=file        Use the notice in the file as the old (to be replaced) string, instead        of the hard coded value in the script.    --newnotice=file        Use the notice in the file as the new (replacement) string, instead of        the hard coded value in the script.    --dry-run        Don't actually make the changes, but print out the list of files that        would change.  When used with -v, a status will be printed for every        file.    -v / --verbose        Print a message for every file looked at, indicating whether the file        is changed or not.'''OLD_NOTICE = '''/***********************************************************Copyright (c) 2000, BeOpen.com.Copyright (c) 1995-2000, Corporation for National Research Initiatives.Copyright (c) 1990-1995, Stichting Mathematisch Centrum.All rights reserved.See the file 'Misc/COPYRIGHT' for information on usage andredistribution of this file, and for a DISCLAIMER OF ALL WARRANTIES.******************************************************************/'''import osimport sysimport getoptNEW_NOTICE = ''DRYRUN = 0VERBOSE = 0def usage(code, msg=''):    print __doc__ % globals()    if msg:        print msg    sys.exit(code)def main():    global DRYRUN, OLD_NOTICE, NEW_NOTICE, VERBOSE    try:        opts, args = getopt.getopt(sys.argv[1:], 'hv',                                   ['help', 'oldnotice=', 'newnotice=',                                    'dry-run', 'verbose'])    except getopt.error, msg:        usage(1, msg)    for opt, arg in opts:        if opt in ('-h', '--help'):            usage(0)        elif opt in ('-v', '--verbose'):            VERBOSE = 1        elif opt == '--dry-run':            DRYRUN = 1        elif opt == '--oldnotice':            fp = open(arg)            OLD_NOTICE = fp.read()            fp.close()        elif opt == '--newnotice':            fp = open(arg)            NEW_NOTICE = fp.read()            fp.close()    for arg in args:        process(arg)def process(file):    f = open(file)    data = f.read()    f.close()    i = data.find(OLD_NOTICE)    if i < 0:        if VERBOSE:            print 'no change:', file        return    elif DRYRUN or VERBOSE:        print '   change:', file    if DRYRUN:        # Don't actually change the file        return    data = data[:i] + NEW_NOTICE + data[i+len(OLD_NOTICE):]    new = file + '.new'    backup = file + '.bak'    f = open(new, 'w')    f.write(data)    f.close()    os.rename(file, backup)    os.rename(new, file)if __name__ == '__main__':    main()
