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!
