In this guide, you’ll master essential Linux file operations—listing, creating, copying, moving, and deleting files and directories—to streamline your workflow on any Unix-like system. ## Table of Contents 1.

[References](#references) ## Key Concepts Before you begin, make sure you understand: * The Linux filesystem tree and hierarchy * The difference between **absolute paths** and **relative paths** * How to navigate directories with `cd` and identify your location with `pwd` Absolute paths start at the root directory `/` while relative paths are based on your current working directory. ## Listing Files and Directories Use the `ls` command to display directory contents: ```bash theme={null} $ ls Documents Desktop Downloads Music Pictures Videos ``` Show hidden files (those starting with a dot) with `-a`: ```bash theme={null} $ ls -a . .. .bashrc .profile Documents Desktop Downloads Music Pictures Videos ``` For a detailed (long) listing including permissions, ownership, size, and timestamp, add `-l`: ```bash theme={null} $ ls -l /var/log total 4064 drwxr-xr-x 2 root root 4096 Oct 18 22:52 anaconda drw------- 2 root root 4096 Oct 18 22:53 audit -rw------- 1 root root 19524 Nov 1 17:56 boot.log ... ``` Combine options to save time: ```bash theme={null} $ ls -al # same as ls -a -l $ ls -ahl # human-readable sizes with -h ``` ## Filesystem Structure Linux organizes files in an inverted tree structure: * Root directory: `/` * Standard subdirectories: `/home`, `/var`, `/etc`, `/usr`, etc. * Each folder can contain files and more subdirectories ### Absolute Paths Absolute paths always begin at `/`.\ Example: ```text theme={null} /home/aaron/documents/invoice.pdf ``` ### Relative Paths Relative paths depend on your current directory. Check it with: ```bash theme={null} $ pwd /home/aaron ``` Change directories using `cd`: ```bash theme={null} $ cd /var/log # absolute path $ cd /home/aaron # absolute path $ cd .. # up one level $ cd documents # down into current dir’s "documents" ``` ![The image shows a directory structure with a command line interface on the left. The directory tree includes folders like "home," "var," and "root," with a file named "Invoice.pdf" under "aaron/Documents."](https://kodekloud.com/kk-media/image/upload/v1752881397/notes-assets/images/Linux-Professional-Institute-LPIC-1-Exam-101-Perform-Basic-File-Management-Part-1/directory-structure-command-line-invoice.jpg) From `/home/aaron`, these relative paths resolve to: * `documents/invoice.pdf` → `/home/aaron/documents/invoice.pdf` * `invoice.pdf` → `/home/aaron/invoice.pdf` * `../invoice.pdf` → `/home/invoice.pdf` * `../../invoice.pdf` → `/invoice.pdf` Additional `cd` shortcuts: ```bash theme={null} $ cd / # go to root $ cd # go to your home directory $ cd - # switch to previous directory ``` ## Creating Files and Directories * Create an empty file: ```bash theme={null} $ touch receipt.pdf ``` * Create a new directory: ```bash theme={null} $ mkdir receipts ``` ## Copying Files and Directories Use `cp [source] [destination]`: * Copy a file into a directory: ```bash theme={null} $ cp receipt.pdf receipts/ ``` * Copy and rename: ```bash theme={null} $ cp receipt.pdf receipts/receipt_copy.pdf ``` * Copy a directory recursively: ```bash theme={null} $ cp -r receipts/ backup_of_receipts/ ``` Ensure `backup_of_receipts` does not already contain a `receipts` subdirectory. ## Moving and Renaming Use `mv [source] [destination]` to move or rename: ```bash theme={null} $ mv receipt.pdf receipts/ $ mv receipts/receipt.pdf receipts/old_receipt.pdf $ mv receipts/ old_receipts/ ``` `mv` works seamlessly on both files and directories. ## Deleting Files and Directories `rm -r` permanently deletes directories and their contents. Use with caution to avoid data loss. * Remove a file: ```bash theme={null} $ rm invoice.pdf ``` * Remove a directory recursively: ```bash theme={null} $ rm -r invoices/ ``` Always include `-r` when deleting directories. ## Summary of Commands | Command | Description | Example | | ------- | ------------------------------------ | -------------------------- | | ls | List directory contents | `ls -ahl /var/log` | | pwd | Print working directory | `pwd` | | cd | Change directory | `cd /home/aaron/documents` | | touch | Create an empty file | `touch newfile.txt` | | mkdir | Create a new directory | `mkdir project` | | cp | Copy files or directories | `cp -r src/ dest/` | | mv | Move or rename files and directories | `mv oldname newname` | | rm | Remove files or directories | `rm -r obsolete_folder/` | ## References * [GNU Coreutils Manual](https://www.gnu.org/software/coreutils/manual/coreutils.html) * [Linux File System Basics](https://www.tldp.org/LDP/intro-linux/html/sect_03_01.html) * [Bash Reference Manual](https://www.gnu.org/software/bash/manual/)
