Good for screenshots, debugging, or flexing your uptime like it means something.

❯ ps

Process inspection without opening a GUI and lying to yourself.

common flags:

-a all processes
-x include processes without a tty
-u user-oriented output
-o custom columns
-p target a PID

show info about the current shell:

      
        bash
        
      
ps -o pid,user,rss,vsz,%mem,%cpu -p $$

❯ kill

For when a process stops responding to hints.

important signals:

-15 ask politely
-9 end the conversation

Use -15 first unless you enjoy cleaning up messes.

❯ tmux

Terminal multiplexer. Once you use it, not using it feels broken.

list sessions:

      
        bash
        
      
tmux list-sessions

output:

      
        bash
        
      
0: 1 windows (created Wed Feb 18 16:53:15 2026) (attached)
1: 1 windows (created Wed Feb 18 18:24:27 2026)

attach to one:

      
        bash
        
      
tmux attach-session -t 0

❯ curl

The Swiss army knife you already use but pretend you understand.

get the weather by city name:

      
        bash
        
      
curl wttr.in/tehran

read the community maintained cheatsheets for any tool:

      
        bash
        
      
curl cheat.sh/bash

retrieve your public IP address:

      
        bash
        
      
curl http://icanhazip.com

output:

      
        bash
        
      
5.126.22.159

you can use the -v flag to see the full request and response:

      
        bash
        
      
curl -v http://icanhazip.com

output:

test a SOCKS proxy:

      
        bash
        
      
start=$(date +%s)

while true; do
    clear
    echo "=== curl google ==="
    if curl -v --socks5 socks5://127.0.0.1:10808 https://www.google.com/generate_204 2>&1 \
        | head -30 | grep -q 'Server hello'; then
        end=$(date +%s)
        echo "success"
        echo "Elapsed time: $((end - start))s"
        break
    fi
    sleep 2
done

same thing, but no proxy, just sanity check:

      
        bash
        
      
start=$(date +%s)

while true; do
    clear
    echo "=== curl google ==="
    if curl -v https://www.google.com/generate_204 2>&1 \
        | head -30 | grep -q 'Server hello'; then
        end=$(date +%s)
        echo "success"
        echo "Elapsed time: $((end - start))s"
        break
    fi
    sleep 2
done

❯ fzf

Fuzzy search for everything. Makes grep feel medieval.

instead of this:

      
        bash
        
      
history | grep "fig"

do this:

      
        bash
        
      
history | fzf

❯ pbcopy

Clipboard glue for macOS. Useful with fzf.

copies the exact command:

      
        bash
        
      
history | fzf --tac --preview 'echo {}' \
| awk '{$1=""; sub(/^ +/, ""); sub(/[[:space:]]+$/, ""); printf "%s", $0}' \
| pbcopy

❯ tee

Split output without losing your mind.

      
        bash
        
      
ls | tee ls-output.txt

❯ nl

Line numbers without opening an editor.

      
        bash
        
      
nl -w1 -s.

❯ grep

Recursive search when you don’t remember where anything lives.

      
        bash
        
      
grep -Rw 'import' | sort

output:

      
        bash

        bash
        
      
ps au | awk '/bat/ && !/awk/ {print}' | bat -l conf

❯ process substitution

Shell black magic that becomes normal fast.

this baiscally means that you can run a command on a file without having to save the changes to a temporary file first,
so you can mae sure the out put is exactly what you want.

changing your name in git config file:

      
        bash
        
      
diff .gitconfig <(sed s/Danial\ M./Diddy/I .gitconfig)
diff <(sort .gitconfig.bak) <(sort .gitconfig)

redirect stdout and stderr separately:

      
        bash
        
      
bash example.sh > >(less) 2> >(tee errors.txt)

real use:

      
        bash
        
      
python3 -m http.server 8080 > >(less) 2> >(tee errors.txt)

even works with editors:

      
        bash
        
      
vim <(cat file1 file2)

❯ rsync / ssh / sshfs

Move files like an adult.

      
        bash
        
      
rsync -av --progress -e 'ssh -p 2222' /home/danial/tmp/os clh@172.30.205.63:tmp/2

mount remote dirs:

      
        bash
        
      
sshfs -p 2222 clh@172.30.205.63:/home/clh/tmp/ /home/danial/part-class/mnted-dir/

❯ lshw

Hardware info when you need facts.

      
        bash
        
      
lshw -C network

onefetch

This is basicly fastfetch for git repositories.

personally, i like running it in every folder automatically,
just put this in your ~/.bashrc or ~/.zshrc and it'll improve your cd command:

      
        bash
        
      
function replace_cd(){
  if builtin cd "$@"; then
    if [ -d "$PWD/.git" ]; then
        onefetch .
    fi
  fi
}

alias cd="replace_cd"

output:

      
        bash
