fgrep:tldr:e2dcf

The command "fgrep ${search_string} ${filename}" is used to search for a specific string within a given file using the "fgrep" command.

Here's a breakdown of the elements in the command:

• "fgrep": It is a command used for searching text patterns within files. It stands for "fixed-string grep" and is also known as "grep -F". It treats the search string as a literal string instead of a regex pattern.

• "${search_string}": This is a variable that represents the string you want to search for within the file. You need to replace "${search_string}" with the actual string you are looking to find.

• "${filename}": This is another variable that represents the name of the file in which you want to search for the given string. You need to replace "${filename}" with the actual name or path of the file.

Putting it all together, the command will search for the "search_string" within the "filename" using the "fgrep" command.
