Shell Programming and Scripting

Newline character "\n" not working for ksh in linux AS 3.0

Command :

$echo "Hi\nHi"
$Hi\nHi
$

Expected output :
$echo "Hi\nHi"
Hi
Hi
$

Can some help me on this

Thanks in advance
Sanish.

either:
/bin/echo '"Hi\nHi"

or [if in bash]:
echo -e "Hi\nHi"

Or you could always use printf....

printf "Hi\nHi\n"

Note - with printf you'll need a trailing newline too

Hi vgersh99 & zazzybob ,

Thanks for the suggestions.

printf helps to resolve the issue in ksh.

But i have issues with other commands also, so i suspect that there is something to do with the shell i.e setting some environment variables or something.

My main issue is with sed

I am expecting the following output from the follwing command

$ sed -e 's/String1/String0\nString1\nString2/' < aa
String0
String1
String2

But i am getting the following output

$ sed -e 's/String1/String0\nString1\nString2/' < aa
String0nString1nString2

Can you please help me on this

sed -e "s/String1/String0`/bin/echo`String1`/bin/echo`String2/" < aa

Hi vgersh99,

thanks for your response, but it did'nt help

$ cat aa
String1

$ cat x
#!/bin/ksh
sed -e "s/String1/String0`/bin/echo`String1`/bin/echo`String2/" < aa

$ ./x
String0String1String2

Seems that it is ignoring the newline

Thanks,
Sanish

\n is a backslash followed by an n. To the shell, backslash removes any special meaning from the character that follows it. n has no special meaning, so the backslash does nothing and you just get an n.

\\n will cause the shell to send a \n somewhere. A very few programs interpret a \n as a newline and these will document that. Everywhere else it is just a back slash followed by a n.

sed accepts \n in an RE. You are not trying to put \n in an RE. To do you want:

# echo string0 | sed 's/string0/string1\
> string2/'
string1
string2
#
