The "pdfgrep" command is a program used to search for a specific text pattern within PDF files. Here is an explanation of the components of the command:

1. "pdfgrep": This is the actual command that executes the pdfgrep program.

2. "${pattern}": This represents the text pattern you want to search for within the PDF file. You need to replace "${pattern}" with the desired pattern. It can be a word, phrase, or a regular expression.

3. "${file-pdf}": This represents the PDF file(s) in which you want to search for the specified pattern. You need to replace "${file-pdf}" with the actual file name or file path(s) that you want to search. If you wish to search through multiple files, you can provide multiple file names or file paths separated by spaces.

So, when you run the "pdfgrep ${pattern} ${file-pdf}" command, it will search for the specified pattern within the provided PDF file(s) and display the matching lines or sections of text containing the pattern.
