外殼還能更「進攻」一點嗎？

我的根圖Linux 是用進攻使用旗幟啟用：

# sudo su -
Password: 
Hold it up to the light --- not a brain in sight!
Password:

也可以選擇財富依攻擊性程度：

# fortune -o kernelcookies | cowsay -b

考慮到連結中提供的風味物品清單1很短 - 而且我個人不使用分子動力學模擬包- 裡面還有那種香料嗎外殼一般在 Linux（或 UNIX）中？

1-記住這一點很好cowsay可以輸出任何參數，而不僅僅是命運，例如命令或腳本的輸出：cowsay -s $(script_in_path_or_command)。注意 -s 僅適用於此處牛的外觀，請參閱線上說明頁。

好吧，透過使用PS1and command_not_found_handle，bash 可能會侮辱你：

anthony@Watt:~$ . /tmp/insult.sh 
anthony@Watt:~$ sl
bash: sl: command not found, incompetent spoony bard
anthony@Watt:~$ ls /wrong/path
ls: cannot access /wrong/path: No such file or directory
Learn to type, second-rate Horrified Heron.
anthony@Watt:~$

這是/tmp/insult.sh我在上面獲取的。

### Data ###
bash_insulter_sentences=(
    'Have you considered Windows, %s?\n'
    'Learn to type, %s.\n'
    'Fell asleep at the keyboard again, %s?\n'
    "Failure is common when you're a %s, isn't it?\n"
)

bash_insulter_subjects=(
    'spoony bard'           # we all played this, right?
    'extra-Warty Warthog'
    'Dazed Drake'
    'Fidgety Fawn'
    'Horrified Heron'       # etc.
)

bash_insulter_adjectives=(
    'incompetent ' # these have built-in spacing
    'inept '
    'second-rate '
    '' # chance of none
    ''
)

### Functions to generate insults ###
bash_insulter_random_element() {
    if [ ${BASH_VERSINFO[0]} -lt 4 ] || \
        [ ${BASH_VERSINFO[0]} -eq 4 -a ${BASH_VERSINFO[1]} -lt 3 ]; then
        # bash before 4.3 doesn't have -n
        eval "local var=(\"\${$1[@]}\")"
    else
        local -n var="$1"
    fi
    local len=${#var[@]}
    echo -n "${var[$RANDOM % len]}" # Slightly biased. Don't care.
}

bash_insulter_full_subject() {
    bash_insulter_random_element bash_insulter_adjectives
    bash_insulter_random_element bash_insulter_subjects
}

bash_insulter_do_insult() {
    printf "$(bash_insulter_random_element bash_insulter_sentences)" "$(bash_insulter_full_subject)"
}

### set up ###
command_not_found_handle() {
    echo "bash: $1: command not found, $(bash_insulter_full_subject)"
    return 127
}

PS1='`
    if [ 0 -ne $? -a 127 -ne $? ]; then
        bash_insulter_do_insult
    fi
    echo "\u@\h:\w\$ "; 
`'

有人提到sl。在像解釋器這樣的軟體中，其目標是最大的可預測性，驚喜在上下文中當然可以算是「冒犯性」的東西。手冊還列出了適當的選項：

DESCRIPTION
   sl  is a highly advanced animation program for curing your bad habit of
   mistyping.

   -a     An accident is occurring. People cry for help.

   -l     Little version

   -F     It flies like the galaxy express 999.

   -c     C51 appears instead of D51.

……還有一個有趣的漏洞:

BUGS
   It sometimes list directory contents.
