I have one multiline text box. This box contains large string which has new line breaks.I want to display first 10 chars of each line or paragraph in a multiple text. My multiple text box contains more than 100k chars. Is there any best solution to retrieve string using regex?

Example input:

this is sample test
I am from australia
I am from India

The expected output is the first 10 chars of each new line/paragraph followed by ...

this is sam...
I am from a..
I am from I..

Try this regex to find the first 10 characters: ^(.{10})(.*)$ and replace with $1... 

output = input.replace(/^(.{10})(.*)$/gm, '$0...')
print(output[<line>])

Note this will match I am from␠ instead of I am from a because it counts spaces too.
