腳本問題

如何建立一個腳本來詢問使用者檔案名稱然後建立該檔案？

我已經嘗試過這個：

#!/bin/bash
#Get Script name of this file and create it
#Get Author's name of this file
#Add the date this file is ran
#Add a "Hello"

echo -n "Please type Script destination file name: "
read 0

echo -n "Please type your name: "
read name

if [ -z "$0" ]
then
    echo "No Script name given."
else
    echo "#Script: $0" > $0
fi

if [ -z "$name" ]
then
    echo "No name given."
else
    echo "#Author: $name" >> $0
    echo "#Date: `date`"  >> $0
fi

您的問題是使用 $0 作為變數名。這是為被呼叫的腳本的名稱保留的；嘗試僅使用echo $0;.此外，超出此範圍的每個整數變數都保留用於傳遞給腳本的參數。

以下是腳本的更新版本，可以按預期工作。我已將 $0 變更為 $filename，將 $name 變更為 $username。

#!/bin/bash
#Get Script name of this file and create it
#Get Author's name of this file
#Add the date this file is ran
#Add a "Hello"

echo -n "Please type Script destination file name: "
read filename

echo -n "Please type your name: "
read username

if [ -z "$filename" ]
then
    echo "No Script name given."
else
    echo "#Script: $filename" > $filename
fi

if [ -z "$username" ]
then
    echo "No name given."
else
    echo "#Author: $username" >> $filename
    echo "#Date: `date`"  >> $filename
fi
