In a set if you have the option to change directly in the file instead of printing the change output
to screen.
But firstly print the content of our file.
Table that text because we will change input file directly to that copy table text 2 tables do dot text.
Now if you would like to print only a line containing button.
Peter the values set with option an s an address we would use a regular expression for searching string.
Peter.
And as a command we would use be a sprint input file would be table to text and under option I.
After optional M and push and then we don't see any output.
This is because we are placing output of said command directly to input file and not to the screen.
If the open input file table to the text if you see only a line with Peter Gade now remove table to
file and create it again by copying original file table that text we can check output of table to the
text.
Let's say we want to change input file by appending line after line with the bottom.
Peter
so bright said
use I as an option will be directly changing input file as an address.
Use Peter that Aguara expression for searching pattern Peter.
And as Kamandi was a B option after Peter input file of be table to the text and we see here that we
have no output printed to the screen.
So let's check content of table to file and we see here new line after line with beat a pattern great
using option I is very powerful.
So be aware that you are affecting the input file.
