fgrep:tldr:44066

The command "fgrep -c ${search_string} ${filename}" is used to search for a specific string in a file and count the number of occurrences of that string.

Here is a breakdown of the command:

• "fgrep" stands for "fixed grep" and is a command-line tool used for searching patterns in text files.
• "-c" option is used to count the number of lines that contain the searched string in the file.
• "${search_string}" refers to the string you want to search for in the file. It should be replaced with the actual string you want to search for.
• "${filename}" refers to the name of the file in which you want to search for the string. It should be replaced with the actual file name you are working with.

So, when you run the command with the appropriate values for "${search_string}" and "${filename}", it will search for the given string in the specified file and return the count of the number of lines that contain the searched string.
