How to use a scalar variable as part of transliterate? My perl program asks for the original string and replacement string and the data file to be acted upon. I read my original and replacement string into scalar variables $orig and $replace as well as data filename to $fname How do I carryout the following? $fname =~ tr/$orig/$replace/g I read in the perl docs that it is not possible to use variable as part of tr///. However is there any other way of carrying this out. datafile contents are aaabbbcccddd $orig = 'abc' $replace = 'def' The goal of the program is to replace the characters in the data file such that the new data file contents would be dddeeefffddd Any help will be appreciated.

  • 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.
