NAME pbr - Perl-based Batch Rename SYNOPSIS pbr [-c] [-d *dest_dir*] [-D] [-i] [-l] [-p] [-t] [-v] [-w] PerlExpression Files ... See below for description of the switches. DESCRIPTION *pbr* is a perl-based batch renaming tool. Normally you wouldn't care about the implementation language of a tool, but in this case proper usage depends on your knowledge of perl. The first argument to this program should be a perl expression that modifies $_. The remaining arguments are files that will potentially be renamed. Each file name is temporarily placed in $_. The given expression is then "eval"ed. Only if executing the expression results in the file name being changed, is the file renamed accordingly. For example, if one of your input file names is "foo.txt" and your expression "s/o/O/g", the renamed file will be "fOO.txt". On the command line, this would appear as: pbr s/o/O/g foo.txt If your input file above was "bar.txt", no change or rename would be made.
