Some code I append to my .bashrc for quality of life improvements.

bashrc_QoL_additions.sh

# Allows the user to run .py, .sh and .c implicitly through filename extensions rather than delcaring it in a command.
# Note that tempc needs to be installed to run c files. Get it here! -> https://github.com/Qu1ck5h0t/tempc
command_not_found_handle() {
    if [[ "$1" == *.py ]]; then
        python3 "$1"
    elif [[ "$1" == *.sh ]]; then
        chmod +x "$1"
        ./"$1"
    elif [[ "$1" == *.c ]]; then
        tempc "$1"
    else
        echo "Command not found: $1"
        return 127
    fi
}

# Clears the terminal by just typing "c"
alias c='clear'

# Runs the last command in sudo when the user types "please"
alias please='sudo $(history -p !!)'
