grep -R searches all files in a directory and outputs filenames and lines containing matched results. -R stands for “recursive”. Above, grep -R searched the /home/ccuser/workspace/geography directory for the string “Arctic” and outputted filenames and lines with matching results.
grep -Rl searches all files in a directory and outputs only filenames with matched results (so no lines). l (a lowercase L, not a capital i) stands for “files with matches.” Here grep -Rl searched the /home/ccuser/workspace/geography directory for the string “Arctic” and outputs filenames with matched results.
Instructions
Use grep search through the working directory (/home/ccuser/workspace/geography) for anything that matches Island. We want the matching filenames and lines.
Conduct the same search using grep, but without the matching lines.
