I'm tailing logs and they output \n instead of newlines.
I thought I'd pipe the tail to awk and do a simple replace, however I cannot seem to escape the newline in the regex. Here I'm demonstrating my problem with cat instead of tail:
test.txt:
John\nDoe Sara\nConnor cat test.txt | awk -F'\\n' '{ print $1 "\n" $2 }' Desired output:
John Doe Sara Connor Actual output:
John\nDoe Sara\nConnor So it looks like \\n does not match the \n between the first and last names in test.txt but instead the newline at the end of each line.
It looks like \\n is not the right way of escaping in the terminal right? This way of escaping works fine in e.g. Sublime Text:
993
So: Press CTRL-h and the Replace dialog will open. Type \r\n in "Find what" and \\r\\n in "Replace with". Then select search mode Extended (\r, \n, \t, \x..., \0) and click "Replace All".
Original answer:Append printf "\n" at the end of each awk action {} . printf "\n" will print a newline.
Create a string containing line breaksInserting a newline code \n , \r\n into a string will result in a line break at that location. On Unix, including Mac, \n (LF) is often used, and on Windows, \r\n (CR + LF) is often used as a newline code.
How about this?
$ cat file John\nDoe Sara\nConnor $ awk '{gsub(/\\n/,"\n")}1' file John Doe Sara Connor If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
