+> additional useful terminal functions
+Here are some additional terminal functions and tricks that can make your workflow more efficient.
+
+---
+
+### Process Management
+- `ps`: Lists running processes. For example, `ps aux` shows all processes for all users. you can combine this with grep to get PIDs easily
+
+- `kill <PID>`: Terminates a process by its ID. For example, `kill 1234` terminates the process with PID '1234'.
+
+- `killall <name>`: Terminates a process by its name. For example, `killall firefox` closes all Firefox instances.
+
+- `top` or `btop`: Monitors system resources interactively. For example, run `btop` for a detailed, interactive view of processes.
+
+---
+
+### Archiving and Compression
+- `tar -cvf archive.tar <files>`: Creates a tar archive. For example, `tar -cvf backup.tar ~/documents/` creates 'backup.tar' from the 'documents' directory.
+
+    mnemonic: tar Compress Ze File
+
+- `tar -xvf archive.tar`: Extracts a tar archive. For example, `tar -xvf backup.tar` extracts the contents of 'backup.tar'.
+
+    Mnemonic: tar eXtract Ze File
+
+- `gzip <file>`: Compresses a file. For example, `gzip largefile.txt` compresses 'largefile.txt' to 'largefile.txt.gz'.
+
+
+- `gunzip <file.gz>`: Decompresses a `.gz` file. For example, 'gunzip largefile.txt.gz' restores the original file.
+
+---
+
+### Networking
+- `ping <host>`: Checks connectivity to a host. For example, `ping google.com` tests the connection to Google.
+- `curl <URL>`: Downloads or interacts with a URL. For example, `curl https://example.com` retrieves the content of the webpage.
+- `wget <URL>`: Downloads a file from a URL. For example, `wget https://example.com/file.zip` downloads 'file.zip'.
+- `ssh <user>@<host>`: Connects to a remote machine. For example, `ssh den@192.168.1.100` attempts to connect over SSH to the remote machine at ip '192.168.1.100' as user 'den'.
+
+---
+
+### System Information
+- `uname -a`: Displays system information. For example, `uname -a` shows the kernel version and system architecture.
+- `df -h`: Displays disk space usage. For example, `df -h` shows disk usage in a human-readable format.
+- `free -h`: Displays memory usage. For example, `free -h` shows RAM and swap usage in a human-readable format.
+- `uptime`: Shows how long the system has been running. For example, `uptime` displays the system uptime and load averages.
+
+---
+
+### Terminal Shortcuts
+- `Ctrl+C`: Interrupts the current command.
+- `Ctrl+Z`: Suspends the current command (sends it to the background).
+- `Ctrl+D`: Exits the current shell or sends EOF (End of File).
+- `Ctrl+R`: Searches through command history.
+- `!!`: Repeats the last command. For example, `sudo !!` repeats the last command with `sudo`.
+- `Tab`: Auto-completes file or command names.
+
+---
+
+### Aliases
+Create shortcuts for frequently used commands by adding aliases to your `.zshrc` file. For example:
+alias ll='eza -l'
+alias gs='git status'
+
+After adding, run `source ~/.zshrc` to apply the changes.
+
+the following aliasses exist by default:
+
+find - replaces the default "find" command with a fzf menu that shows previews.
+microfind - like find, but will open the selected file in micro
+ls - replaces ls using eza, defaults to using list mode with colors, grouping and icons.
+la - like ls, but lists all files
+ll - lists in long format
+lt - lists using tree format up to 4 layers deep 
+l. - lists only hidden files
+update - runs `sudo pacman -Syu`
+jctl - runs a minimal journalctl command
+cmdhist - opens a menu to go through your command history and select one, then types that back into the terminal. 
+tipme - gets a random tip
+cowtip - gets a random tip from an RGB cow
+
+
+### fzf
+
+you can use fzf inside your terminal by typing <**> and pressing <tab>. this will give you an fzf menu for autocompleting filepaths. 
+
+---
+
+### Environment Variables
+- `printenv`: Displays all environment variables. For example, `printenv` lists variables like `PATH` and `HOME`.
+- `echo $VARIABLE`: Prints the value of a specific variable. For example, `echo $HOME` prints your home directory path.
+- `export VARIABLE=value`: Sets an environment variable temporarily. For example, `export EDITOR=micro` sets `micro` as the default editor for the current session.
