how can i print unicode characters when tailing a log?-CodePudding

I have log files have things like \u003c scattered throughout them. When I run a command like tail -f log.txt, I see escaped unicode characters everywhere, and am wondering what can I do to properly display these characters so I am not seeing escaped stuff?

EDIT:

>cat log.txt

>hexdump log.txt

CodePudding user response：

You could use printf for translating this kind of escape sequence:

tail -f log.txt |
while IFS='' read -r line; do printf '%b\n' "$line"; done

CodePudding user response：

You can pipe the output of tail -f into hexdump.

tail -f log.txt | hexdump
