sed break into lines (advanced)
2
I'm looking to use sed (or combining it with another grep command)to convert the following string
John: Hi!,How are you,?,Dylan: Hey,OK
into
John: Hi!
John: How are you
John: ?
Dylan: Hey
Dylan: OK
If that's not possible I'm willing to compromise for
John: Hi!,How are you,?
Dylan: Hey,OK
Many thanks

sed can be used.
There is a great Sed - An Introduction and Tutorial by Bruce Barnett online page, which I always open aside when writing sed script.
Give a try to this:
printf 'John: Hi!,How are you,?,Dylan: Hey,OKn' | sed -n '
:1
/./ {
/^[^:,][^:,]*: / {
h
s/^([^:,][^,:]*: ).*$/1/
x
s/,/n/
P
D
}
x
/./ {
x
H
x
s/n//g
x
s/.//g
x
b 1
}
}'
The output is:
John: Hi!
John: How are you
John: ?
Dylan: Hey
Dylan: OK

From my point of view both/./ {and the corresponding closing bracket}can be omitted.

$ awk 'BEGIN{RS=","}{if($1~/:$/)p=$1;print ($1==p?"":p " ") $0}' file
John: Hi!
John: How are you
John: ?
Dylan: Hey
Dylan: OK
There will be an extra empty line in the end. For some awks (at least GNU awk, mawk and Busybox awk) you can use RS="[,n]".

With trand awk:
tr ',' 'n' <file | awk '/:/{name=$1; print; next}; {print name,$0}'
or shorter:
tr ',' 'n' <file | awk '/:/?name=$1:$0=name " " $0'
Output:
John: Hi!

You may try to do something like this:
echo 'John: Hi!,How are you,?,Dylan: Hey,OK' | sed -E "s|(w+:)|n1|g"
It will return:
John: Hi!,How are you,?,
Dylan: Hey,OK

In single awk, considering that your Input_file is same as shown samples then following may help you here.
awk -F',' '
{
for(i=1;i<=NF;i++){
if($i~/:/){
if($i ~ /: /){
print $i
split($i,array," ")
val=array[1]
}
else{
val=$i
}
}
else{
print val,$i
}
}
}' Input_file

You may try to do something like this:
echo 'John: Hi!,How are you,?,Dylan: Hey,OK' | sed -E "s|(w+:)|n1|g"
It will return:
John: Hi!,How are you,?,
Dylan: Hey,OK
