I’m searched for a long time how to do a simple string manipulation in UNIX
I have this string:
theStr='...............'
And I need to change the 5th char to A, How can it be done?
In C# it’s done like this theStr[4] = 'A'; // Zero based index.
You can achieve this with
sed, the stream line editor:echo $theStr | sed s/./A/5First you pipe the output of $theStr to sed, which replaces the fifth character with A.
