name="Alice" greeting="Hello, " message="${greeting}${name}! Welcome to Bash String Concatenation." echo "$message" # 输出: Hello, Alice! Welcome to Bash String Concatenation. 在这个例子中,由于greeting变量包含空格,我们使用双引号"将${greeting}${name}!和后面的文本括起来,以确保整个字符串被...
用技术术语来说是字符串 连接(concatenation),这是 Bash 中最简单的字符串操作之一。 你只需像这样一个接一个地使用字符串变量: str3=$str1$str2 还能比这更简单吗?我觉得不能。 让我们看一个例子。这是我的示例脚本,名为 join.sh: #!/bin/bash read -p "Enter first string: " str1 read -p "...

echo命令用于打印值。{#string}给出了字符串的长度。 拼接两个字符串 将一个字符串添加到另一个字符串的末尾;这个过程称为字符串拼接(string concatenation)。 为方便演示,我们首先创建两个字符串str1和str2,如下所示: str1='hand' str2='book'
Example of getting string length in bash 正如你所看到的,第二个示例中有两个单词,但由于它用引号引起来,因此它被视为单个单词。连空格都算作一个字符。 在Bash 中连接字符串 用技术术语来说是字符串 连接(concatenation),这是 Bash 中最简单的字符串操作之一。
