sed or other way to replace last , with \n

sed or other way to replace last , with \n


I can do it with some auxiliary echo command but not with sed directly...

CODE --> text

$ printf "1,2,3,4,"
$ printf "1,2,3,4,"|sed 's/\,$/4/'
$ printf "1,2,3,4,"|sed 's/\,$/\n/'
$ printf "1,2,3,4,"|sed 's/\,$//';echo
$ { printf "1,2,3,4,"|sed 's/\,$//';echo; }

RE: sed or other way to replace last , with \n

You can't remove that '$' because it's not part of the output. It's your command line prompt. The "printf" command does not add a new line at the end of the output, so your command line prompt is appearing at the end of the output string.

Try this...


# Using printf with a newline character (\n)
printf "1,2,3,4,\n"

# Using print (which adds its own newline)
print "1,2,3,4," 



# This makes it a bit more obvious

RE: sed or other way to replace last , with \n

Oh, I think I misunderstood the question.

Try this...


printf "1,2,3,4,\n" | sed 's/,$//g'

# or

print "1,2,3,4," | sed 's/,$//g'
