newline using sed.

You have to use like this

[samba@samba-lx1 ~]$ echo abc~~~def~~~ghi~~~jkl~~~mno~~~pqr~~~ | sed s/"~~~"/\\n/g
abc
def
ghi
jkl
mno
pqr

[samba@samba-lx1 ~]$

Also, please note that in your original you missed one ~ before p

try this
sed 's/$/\n/g' /yourfile

echo 'abc~~~def~~~ghi~~~jkl~~~mno~~pqr~~~' | sed "s/~~~/\n/g"
works just fine

oops
sed 's/~~~/\n/g'

$ echo abc~~~def~~~ghi~~~jkl~~~mno~~~pqr~~~ | sed s/"~~~"/\\n/g
abcndefnghinjklnmnonpqrn
$

i am not getting the correct result...

Well, You not running right command. Try mine.

echo 'abc~~~def~~~ghi~~~jkl~~~mno~~~pqr~~~' | sed 's/~~~/\n/g'

ravenpl: Not working...

$ echo abc~~~def~~~ghi~~~jkl~~~mno~~pqr~~~ | sed "s/~~~/\n/g"
abcndefnghinjklnmno~~pqrn
$

What shell? It works here, try
echo 'abc~~~def~~~ghi~~~jkl~~~mno~~pqr~~~' | sed 's/~~~/\n/g'

well don't use "" in sed
U are using:
$ echo abc~~~def~~~ghi~~~jkl~~~mno~~pqr~~~ | sed "s/~~~/\n/g"

But Experts said to u
$ echo abc~~~def~~~ghi~~~jkl~~~mno~~pqr~~~ | sed 's/~~~/\n/g'

hey guys
isnt it what i sent ?
echo 'abc~~~def~~~ghi~~~jkl~~~mno~~~pqr~~~' | sed 's/~~~/\n/g'

Sorry Experts said to use

echo "abc~~~def~~~ghi~~~jkl~~~mno~~pqr~~~" | sed 's/~~~/\n/g'

hi kosarajudeepak
we are all experts
the name is on the right

kosarajudeepak:  Not working...

sed 's/~~~/\n/g' yourfile > newfile

Oren: Experts I mean every one who replied before I started commenting to this question, all of you had suggested the correct way to add newline character as per author request, but author was bit confused with " vs ' when using sed. so I was trying to correct the typo.

0ren: This will no way work.

yes it will

its exactly what you asked for
did you try it ?

vishali_vishu: what shell You are using? It works for few people here, but You?

yes i tried that..... as per my search ...sed doesn't recognize \n \t characters.

ravenpl: korn shell....

i dont think the shell matter
sed is not a shell command and the syntax here is basic.

works on ksh as well

vishali_vishu

did you try sed 's/~~~/\n/g' yourfile > newfile
which part didnt work ?

0ren: It is replacing ~~~ with n

then try
sed 's/~~~/\\n/g' yourfile > newfile

Are You sure You surrounding the s/~~~/\n/g with quotes?
Anyway, try 's/~~~/\\n/g' then

did you copy the line exactly ?
i tried it on ksh,bash and it worked
please send a line from your input file
and the exact sed line you are running

0ren: no luck

~~~ is replaced with literal \n (not new line)

vishali_vishu

sed 's/~~~/\n/g' yourfile > newfile

thats the line

please send a line from your input file
and the exact sed line you are running

#!/usr/bin/ksh
echo "abc~~~def~~~ghi~~~jkl~~~mno~~~pqr~~~" | sed 's/~~~/\\n/g'

------ i tried this and the o/p is :abc\ndef\nghi\njkl\nmno\npqr\n

oren@orendesktop ~ > cat test
#!/usr/bin/ksh
echo "abc~~~def~~~ghi~~~jkl~~~mno~~~pqr~~~" | sed 's/~~~/\n/g'
oren@orendesktop ~ > ./test
abc
def
ghi
jkl
mno
pqr

here is the script
unless you have a different ksh it should work for you

echo "abc~~~def~~~ghi~~~jkl~~~mno~~~pqr~~~" | sed 's/~~~/\n/g'

Strangely it haven't worked on my side, thus
echo "abc~~~def~~~ghi~~~jkl~~~mno~~~pqr~~~" | sed "s/~~~/\\n/g"
have

use one backslash

Hello Vishali,

Can you use this

echo "abc~~~def~~~ghi~~~jkl~~~mno~~~pqr~~~" | sed s/"~~~"/\n/g

sambasiva: nope...

~~~ is getting replace with nothing.

Vishali

create a small script


#!/usr/bin/ksh
echo "abc~~~def~~~ghi~~~jkl~~~mno~~~pqr~~~" | sed 's/~~~/\n/g'

chmod it to 755
and run it

tell me if it didnt work

Oren: i did the same...no luck.

try it on bash
its look like something is really wrong with your system
i gave up

good night

Not sure how one of \ is missing. This one worked for me

echo "abc~~~def~~~ghi~~~jkl~~~mno~~~pqr~~~" | sed s/"~~~"/\\n/g

Can you give us o/p of            set |grep SH to see what is your shell

I even verified the
#!/usr/bin/ksh
echo "abc~~~def~~~ghi~~~jkl~~~mno~~~pqr~~~" | sed 's/~~~/\
/g'
is working fine

http://www.computing.net/answers/unix/sed-newline/5640.html

OK, so what's Your sed & OS versions?
You said it's linux, and linux uses gnu sed since always.

when i do at the command line i am getting the correct o/p

cat $1.temp | sed 's/~~~/\
/g'


but when i include this in the script file...not working.

try awk

# echo "abc~~~def~~~ghi~~~jkl~~~mno~~~pqr~~~" | awk 'BEGIN{FS="~~~";OFS="\n"}{$1=$1}1'

Hi vishali_vishu,

All sed's are not created equally.  :(

In linux, the simple \n usually works.  

In some versions you can use the hex value (\0A) in the string.

And in others, you can you the *y* sub-command, though it's not very flexible.

echo "abc~~~def~~~ghi~~~jkl~~~mno~~~pqr~~~" | sed 's/~~~/~/; y/~/\n'

The down-side is that if the text contains the ~ character, the *y* sub-command will change it, too.


Good Luck,
Kent
