What is SED?

A stream editor is used to make text changes on an input stream. SED works by making only one pass on the input (s), and is more efficient as a result. But it is SED's ability to filter text in a pipeline that specifically distinguishes it from other types of editors.


Uses of SED:-

Use of Sed is as follows:

1. Substitution of text
2. Selective printing of text files
3. In-a-place editing of text files
4. Non-interactive editing of text files.

Sed Example:-

1. sed -f script.sed file.txt 
2. sed '$d' file.txt


1. Write all commands in script.sed and execute them.
2. Delete the last line.
