To match a tab, you need to include an actual tab in your sed script.  To replace it with a newline, you need to include an actual newline, escaped by a '\'.

So the script would have the following characters:

  's' '/' TAB '/' '\' NL  '\' 'g' NL

What's not to understand?  I gave you the script that you wanted, character for character.  The line following the script is the HEX values.

Since I cannot enter a TAB character into this editor, I have replaced each TAB with a '@' in the following.

The script would look like the following in a text editor:


If you want to use it inline in a shell script, that would obviously depend on your shell.  But this would work in most shells:

sed 's/@/\
/g' infile > outfile

If you are having problems in entering a tab character from the
shell try <control v> <tab character>. (For eg. bash
does not allow to enter tab character.)

I just noticed a typo in the original post.  It had a '\' instead of '/', although the hex code for the character was correct.  It should have been:

  's' '/' TAB '/' '\' NL  '/' 'g' NL
  73  2f  09  2f  5c  0a  2f  67  0a
