This is useful for renaming multiple files at once. =item B<-p>, B<--preserve> Detect I<src-file> and I<dst-file> having equal content and not touch existing destination files, thus perserving timestamps. This is useful for applications that monitor timestamps, i.e. suppress make(1L) repeating actions for unchanged files. =back =head1 EXAMPLE # shell script shtool move -v -e '*.txt' %1.asc # Makefile scanner.c: scanner.l lex scanner.l shtool move -t -p lex.yy.c scanner.c =head1 HISTORY The B<GNU shtool> B<move> command was originally written by Ralf S. Engelschall E<lt>rse@engelschall.comE<gt> in 1999 for B<GNU shtool>. =head1 SEE ALSO shtool(1), mv(1), make(1). =cut
