I am working on a command that replaces all digits 0-9 with their corresponding letters in sed. I know I'm doing something wrong, but sed is not interpreting the replacement regex as anything but a string literal.



The command I am using is sed -r 's/[0-9]/[A-J]/g' log > ~/output.txt



It seems pretty straightforward to me, but I have been stuck on it for about an hour. The output I receive just replaces 0-9 with the string "[A-J]"






linux command-line bash regex sed

          You want transliteration, not substitution, so replace s with y:



          echo 34031445 | sed 'y/0123456789/ABCDEFGHIJ/'


          sed can't use ranges in y, but Perl can:



          echo 34031445 | perl -pe 'y/0-9/A-J/'


          Or just use tr:



          echo 34031445 | tr 0-9 A-J

          • Agreed. tr is the easiest and probably the fastest tool for the job.

          One-line joke

          A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
