( [id://3333]=superdoc: print w/replies, xml ) Need Help??
Hi all great people,

Today I read about using $^I from the following node in perlmonks, Use $^I (was Re: updating a file)
After that I have written a samle code and checked for the same.

#!/bin/perl local $^I = "sub/.bak"; local @ARGV = ('/home/antony/perl/'); while ( <> ) { s/instance/NEW_PATTERN/; print; }

I got the following error.
Error: Can't rename /home/antony/perl/ to /home/antony/perl/l.plsub/.bak: + No such file or directory, skipping file at l line 6.
1) what's wrong with the above code? Is the backup should reside in the same directory?

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.
