fgrep:tldr:b0f2e

The fgrep command searches for a given string in a specified file(s) and returns the lines containing the string. Here's a breakdown of the command syntax:

• fgrep: This is the command itself. It stands for "fixed grep" and is used to search for exact, fixed strings.
• -n: This option is used to display line numbers along with the matching lines. It helps in identifying the position of the string within the file.
• ${search_string}: This is a placeholder for the string you want to search for. You should replace ${search_string} with the actual string you want to find.
• ${filename}: This is a placeholder for the name of the file(s) you want to search within. You need to replace ${filename} with the actual file name or a wildcard pattern if searching in multiple files.

To use this command, you would replace ${search_string} with the desired string and ${filename} with the name of the file(s) to search in. For example:

fgrep -n "example" file.txt

This command would search for the string "example" in the file named file.txt and display the matching lines with line numbers.
