tr command - how to replace the string "\n" with an actual newline (\n) [closed]

Question

I would like to use the tr command to replace all occurrences of the string "\n" with a new line (\n).

I tried tr '\\n' '\n' but this just seems to match any '\' and any 'n'

Here's how to do it with sed:

sed 's/\\n/\n/g' 

Example usage:

To replace all occurrences of \n in a file in-place:

sed -i 's/\\n/\n/g' input_filename 

To replace all occurrences of \n through a pipe, and save into another file

cat file1 file2 file3 file4 | sed 's/\\n/\n/g' > output_file
