sed problem

Oke... sed-hell again.

Case: I have a file that has lines separated by pipe chars. I need to split
it back into a line-by-line file. So I tried this (the ^M has been entered
by pushing Ctrl+V, Enter):
echo "This|should|be|on|separate|lines" | sed -e "s/|/^M/g"

The result:
linesate

I'm sure I'm missing something, but hours of googling didn't get me
anywhere. Any ideas?

Thanks
Jens

The Unix line seperator is LF (ASCII 10, ^J), not CR (ASCII 13, ^M).
Sending a lone CR to a terminal will simply move the cursor to the
begnning of the line, so you are seeing all of the lines printed on
top of each other ("separate" is the longest line, so it overwrites
everything; "lines" then overwrites the first 5 characters of
"separate", leaving "linesate" on the terminal).

What you actually want is:

echo "This|should|be|on|separate|lines" | sed -e 's/|/\^J/g'

where the ^J is entered using Ctrl-V Ctrl-J. Note the use of single
quotes rather than double quotes, and the backslash before the ^J.
Both of these are necessary to prevent the LF being interpreted by
either the shell or sed.

Re: sed problem

I'm probably wrong, but isn't ^M the DOS newline character thingy, which you see when opening Windows/DOS files in *nix? Wouldn't \n be right for *nix?

I think awk fits better for this task, IMHO of course :-)

csoler@gudu$ echo "This|should|be|on|separate|lines" | awk -F"|" '{for=20
(i=3D1; i<=3D NF; i++) print $i}'
This
should
be
on
separate
lines

I hope this helps you...

Cheers,
C=E9sar

Re: sed problem

I think "tr" does this even easier (IMHO of course ;)

hal:~ # echo "This|should|be|on|separate|lines" | tr \| \\n
This
should
be
on
separate
lines

Re: sed problem

sed 's/|/\n/g'

(( I like using single quotes, because you're less likely to get
characters like '\' and '$' eaten by the shell ))
