Activity 6 - A BAD File

Workshop Resources

I know I had a file secret-message.txt with one of my favorite quotes in it. “Do. Or do not. There is no try.” Can you help me find it?

Searching for a pattern in a file?

grep is a command used to search for text within files. There are different flags or options that can change how it is used.
The format is: grep [flag] “[pattern]” [filename].

flagsUses
-cTo get the number of files with the pattern.
-iTo make the search case-insensitive. “uNiX” is the same as “unix”
-nTo return matched lines and their line numbers.
-RSearch all files in current directory.

Let’s practice this command to find my secret-message.txt! Let’s try the following command:

cd
grep -R "Do. Or do not. There is no try."

grep command


Why does the secret-message file look like that?

Remember that file we saw with the strange name? It was called malware.sh. We should go find it again and take a closer look at it. I think this was left by the hackers!

find is a command used to search for a file with certain parameters within a directory or region of files. It can be used in multiple ways including:

Use the find command to search for the file within the current directory. Is there a command we can use to figure out what the current directory is?
