Sed is a powerful text-processing tool used in Linux/Unix environments
sed can be used for a variety of tasks, like searching and replacing, inserting or deleting, filtering, and much more
The basic syntax of sed is as follows:
sed [OPTIONS] [COMMAND] [FILE(s)]
Search and Replace:In sed This can be done using the 's' command, which stands for substitute.
"sed 's/old/new/g' example.txt"
If you want to modify the file directly without creating a new one, you can use the '-i' flag.
"sed -i 's/old/new/g' example.txt"
Sed supports regular expressions, which are a powerful way to search for patterns in text
Sed allows you to chain multiple sed commands together using the ';' separator
In sed you can use any separator(not only /)
