Good afternoon all,
I want to ask how to change some letter in my file with other letter in spesific line
eg.
data.txt
for example i want to change the 4th line with character 1.
How could I do it by SED or AWK.
I have tried to run this code but actually did not modify the data.txt file and just print the result to screen.
