Shell scripting string manipulation

Hi,

if I have a string delimited by commas how can I put each character on a new line followed by a carriage return, and output this to a filee.g

from:

s,t,r,i,n,g

to

s
t
r
i
n
g


thanks you

Code:
echo "s,t,r,i,n,g" | tr ',' '\n'

Tools I think tr is the better command, but here it is with awk

Code:
>echo s,t,r,i,n,g | gawk 'BEGIN {RS=","}{print $1}'
s
t
r
i
n
g

I would use sed, like this:

Code:
s/,/\
/g

This simply uses a substitution command to replace each comma with a newline. You would have to store the string in a file first, then feed the file into the sed script, like this:

Code:
sed -f sedscript file

Then just delete the file when you're done with it.
