Top Forums UNIX for Beginners Questions & Answers Replace Pattern with another that has Special Characters Post 303033402 by Don Cragun on Thursday 4th of April 2019 08:51:51 PM

As RudiC said, you can use characters other than "/" as the field delimiter in sed, but there are two characters that the standards say cannot be used: a <newline> character and a <null> character are not allowed as the field delimiter.

Note that nothing says that the delimiter has to be a printable character. If you're in a single person office, using ctl-g (i.e., hold down the control key and then hit the "g" key) uses the terminal's alert character as your field delimiter. On many terminals the alert character is a bell sound (which is why I only suggest using it if you do not have an office mate).

If you do this in a script you will need to heavily comment it since if someone uses cat or lpr to look at your script, it will be unreadable. In vi it will display as ^G.
