The grep command is used to search for text patterns in documents. To use grep command to match a regex pattern, follow these steps:
Open your terminal and type "grep" followed by the regular expression pattern you want to match.
Add the name of the file or directory you want to search after the pattern. For example, if you have a file named "sample.txt" in your current directory, you can search for a pattern "hello" in the file using the following command:
grep "hello" sample.txt
This command will search for any lines that contain the word "hello" in the "sample.txt" file.
grep "^t...r$" sample.txt
This command will search for any lines in the "sample.txt" file that match the pattern.
grep "hello" Documents/*.txt
This command will search for the word "hello" in all text files that end with ".txt" in the "Documents" directory.
Overall, the grep command is a powerful tool for searching for specific text patterns in documents using regular expressions.
