This article will teach you exactly that, along with professional-grade tips. The ls command is your window into the filesystem. The term filedot refers to dotfiles – files beginning with a period ( . ), which are hidden by default. Basic to Advanced ls Usage # Standard list (hides dotfiles) ls Show dotfiles (filedot) – this is what "filedot to ls" means ls -a Long format with hidden files and human-readable sizes ls -lah List with trailing slashes for directories, and show inode numbers ls -ali
| Your term | Likely meaning | Command/Concept | |-----------|----------------|------------------| | filedot | "File dot" (hidden files starting with . ) | ls -a | | to ls | Using the ls command to list | ls | | land | Navigate to a directory named "land" | cd land | | 8 | RAR version 8 (latest compression format) | unrar , rar | | prev | Go back to the previous directory | cd - or cd ../ | | rar new | Create a new RAR archive | rar a archive.rar | filedot to ls land 8 prev rar new
For your workflow: filedot to ls land → cd land , ls -la , then cd - to return to prev . RAR (Roshal ARchive) is a proprietary archive format. Version 8 (RAR 8) introduces faster decompression, larger dictionary sizes (up to 1GB), and improved AES-256 encryption. Installing RAR Utilities on Linux Most distros don't include RAR by default. Install unrar (free) and rar (proprietary but free for personal use): This article will teach you exactly that, along

total 48K drwxr-xr-x 2 user group 4.0K Mar 15 10:30 . drwx------ 52 user group 4.0K Mar 15 10:29 .. -rw-r--r-- 1 user group 12K Mar 14 22:00 .hidden_config -rw-r--r-- 1 user group 5M Mar 15 09:00 document.pdf -rw-r--r-- 1 user group 2.1G Mar 15 08:00 large_video.mp4 The prev keyword suggests you want to return to where you came from after inspecting land . Two ways to go "prev" 1. cd - – Go to previous directory (most common) $ pwd /home/user/projects $ cd land /home/user/projects/land $ ls -la # you do your listing $ cd - /home/user/projects # back to previous! cd - works like a "back" button. It uses $OLDPWD environment variable. 2. cd ../ – Go up one level (parent directory) $ pwd /home/user/projects/land $ cd .. $ pwd /home/user/projects Difference: cd - remembers exactly where you were (even if it was not the parent). cd .. goes up one level in the tree.
The output might look like:
echo "Listing all files (including dotfiles):" ls -lah
