I am doing an online course "Introduction to Linux" 

Home Page

LinuxFoundationX: LFS101x.2 Introduction to Linux

Chapter 13: Manipulating Text; Section 2. sed & awk

~$ cat > test1

This is a Sample Test File for the sed command.

The sed command is used to edit contents in a file.

For example, the sed command is used to replace words in a line or file.

~$ sed s/is/are/ test1

Thare is a Sample Test File for the sed command.

The sed command are used to edit contents in a file.

For example, the sed command are used to replace words in a line or file.

As you can see above the 1st instance of "is" in "This" is replaced by "are" giving "Thare"; BUT the following two lines also have "is" replaced by "are" EXCEPT for the "is" after "Thare". It is ALMOST as if I had invoked the global: sed s/is/are/g test1 EXCEPT for the 2nd "is" after "Thare"?

I am using sed version: sed (GNU sed) 4.2.2

'b'ye - Bruce Gilbert.

"For we have not been given a spirit of fear, but a spirit of Power; of Love; & of a Sound Mind." 2nd Timothy, chapter 1, verse 7.
