fgrep:tldr:45fa3

The command "fgrep -v ${search_string} ${filename}" is used to search for a specific string in a given file while excluding lines that contain that string.

Here's a breakdown of the components:

• "fgrep" is a command that stands for "fast grep." In this context, it is used for performing a simple string search without using regular expressions.
• "-v" is an option for the "fgrep" command that negates the search. It tells the command to display lines that do not contain the search string.
• "${search_string}" is a placeholder for the actual string you want to search for. You should replace it with the desired search term.
• "${filename}" is a placeholder for the name of the file you want to search in. You should replace it with the actual file name, including the path if necessary.

To summarize, this command will search for lines in the specified file that do not contain the given search string and display those lines in the terminal.
