      I have an inbound file that contains many messages. At the end of each message, there is a 0D 0D 0A separating it from the next message. The receiving system that the file is eventually FTP’d to needs the ending characters of every message as 0D 1C 0D

      regsub -all — {DDD} $fileIn “D1CD” newmsg

      Any help would be greatly appreciated. Thank you!

          Nate,

          You will need to use the hex nomenclature for this:

          regsub -all — {x0Dx0Dx0D} $fileIn “x0Dx1Cx0D” newmsg

          You could also use the “string map” command.

          Hope this helps.

            Thank you, James. That worked perfectly! I typically don’t have to replace hex characters, so I was stuck since I couldn’t use the typical n r values for newline and carriage return. Learn something new everyday!
