"... only the FIRST _ character is being replaced ..."

I guessed that you just needed the /g modifier; however, as I've never used File::Rename previously, I ran a test to make sure.

ken@titan ~/tmp/pm_11152739_file_rename $ ls -1 'test 4_5 6' test_1_2_3 'test_a b_c d_e f' $ perl -e ' use strict; use warnings; use File::Rename "rename"; my @files = ( "test 4_5 6", "test_1_2_3", "test_a b_c d_e f", ); rename \@files, { _code => sub { s/_/ /g; }, verbose => 1, no_action => 1, }; ' rename(test 4_5 6, test 4 5 6) rename(test_1_2_3, test 1 2 3) rename(test_a b_c d_e f, test a b c d e f) $ ls -1 'test 4_5 6' test_1_2_3 'test_a b_c d_e f' $ perl -e ' use strict; use warnings; use File::Rename "rename"; my @files = ( "test 4_5 6", "test_1_2_3", "test_a b_c d_e f", ); rename \@files, { _code => sub { s/_/ /g; }, verbose => 1, }; ' test 4_5 6 renamed as test 4 5 6 test_1_2_3 renamed as test 1 2 3 test_a b_c d_e f renamed as test a b c d e f $ ls -1 'test 1 2 3' 'test 4 5 6' 'test a b c d e f'

[Aside: "if (@path != 0) ..." would more usually be written as just "if (@path) ...".]

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
