Do you know where your variables are?

It does even more if you are using the -i flag.

Update: to be more explicit, under -i, a simple eof() will (if needed) pull the next file(s) off of @ARGV, renaming and creating a new file for each until it gets to a non-empty one, and then selects that one as the default output file:

$ rm foo{.bak,};echo bar>foo;perl -i.bak -we'sub show { print STDOUT " +files: ", join(",", glob("*")), "\nselected: $_\n" and select $_ for select *{" +TEMP"} } show; print STDOUT eof() ? "eof\n" : "not eof\n"; show' foo files: foo selected: main::STDOUT not eof files: foo,foo.bak selected: main::ARGVOUT

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 or How to display code and escape characters are good places to start.
