I have a file that I am trying to read by using tail -f. I was wondering if there was a way to have the terminal output an actual line break instead of the \n character.

As a rule, tail -f will display line breaks as line breaks. You may have an issue with your console settings, if that's what you're seeing. – Jon Lasser Mar 25 '10 at 21:50
Or he's tailing a file which actually has a literal \n in it. Maybe line breaks were converted to a literal "\n" before being written to a file. – Josh Mar 26 '10 at 3:09

tail -f file | sed 's/\\n/\n/g'

tail -f file | sed 's/\\n/\n/g' – Vi. Mar 26 '10 at 2:54
Thank you. Fixed. – Dennis Williamson Mar 26 '10 at 3:54
I would like to add that I found I needed to actually physically enter a line break in my sed command after the back-slash in order to make this work, like so: ~$ tail -f /var/log/apache2/error_log | sed 's/\\n/\ > /g' – Jon z Dec 20 '11 at 18:46
Does anyone know of a way to achieve the same thing for multitail? Here's a question:… – fraxture Oct 30 '15 at 14:17
@Kdansky: You didn't show how you defined the alias or what kind of problem you're having so I can only guess. One problem you may be having is with quoting. An extra backslash may help: alias forward="tail -f file | sed 's/\\\n/\n/g'". If you want to be able to specify the filename as an argument, you should use a function instead of an alias: forward () { tail -f "$@" | sed 's/\\n/\n/g'; } – Dennis Williamson Dec 8 '15 at 17:19
tail -1 file | awk '{gsub(/\\n/,"")}1'
