爲測試服務器創建腳本

Question

#!/usr/bin/env zsh ./client localhost 5000 Bryan (my command)

我想檢查我的命令的參數是正確的，在腳本的zsh這意味着：

if 
first argument = int 
second argument = int 
third argument = string 
fi 

Answer 1

只要是明確的，所有這些條件必須腳本繼續是真的，是嗎？此外，請注意「字符串」幾乎意味着任何字符（A-Z，0-9，標點符號） - 除控制字符以外的任何字符。假如是這樣的話，怎麼樣像這樣：

re='^[0-9]+$' 
    echo " " 
    echo "Parm 1: $1" 
    if ! [[ "$1" =~ $re ]]; then 
    echo "The first parameter must be an integer." 
    exit 1 
    fi 

    echo " " 
    echo "Parm 2: $2" 
    if ! [[ $2 =~ $re ]]; then 
    echo "The second parameter must be an integer." 
    exit 2 
    fi 

    re='^[[:graph:]]+$' 
    echo " " 
    echo "Parm 3: $3" 
    if ! [[ $3 =~ $re ]]; then 
    echo "The third parameter must be an string." 
    exit 3 
    fi 
    echo " " 
    echo "Congratulations -- your parms are valid\!" 
    echo " " 

編輯：下面是一些樣品運行：

~/test1$ 
~/test1$./tmp 123 456 abdc 

Parm 1: 123 

Parm 2: 456 

Parm 3: abdc 

Congratulations -- your parms are valid\! 

~/test1$./tmp abc 123 456 

Parm 1: abc 
The first parameter must be an integer. 
~/test1$./tmp 12b 123 abc 

Parm 1: 12b 
The first parameter must be an integer. 
~/test1$./tmp 123 4h5 abc 

Parm 1: 123 

Parm 2: 4h5 
The second parameter must be an integer. 
~/test1$./tmp 123 jkl asdf 

Parm 1: 123 

Parm 2: jkl 
The second parameter must be an integer. 
~/test1$ 
~/test1$ 

希望這有助於！
