echo -e "Dist\tVer\tDate\nCentOS\t7\x2E9\t2018\nUbuntu\t22.04\t2022\nRHEL\t9.2\t2023"??该命令中都使用了哪些转义字符?这些字符的作用是什么?

该命令中使用了以下转义字符:
1. \t:表示制表符,用于在输出中创建水平制表符。
2. \n:表示换行符,用于在输出中创建新的一行。
3. \x2E:表示十六进制转义字符,用于输出"."字符。
这些转义字符的作用是为了在输出中创建特定的格式。通过使用制表符和换行符,可以在输出中创建表格和分行显示的效果。而使用十六进制转义字符可以输出特殊字符,如"."。

echo -e "Dist\tVer\tDate\nCentOS\t7\x2E9\t2018\nUbuntu\t22.04\t2022\nRHEL\t9.2\t2023"?-e选项的作用是什么?
在Linux中,echo命令用于在终端输出文本。而-e选项是echo命令的一个参数,它用于启用转义字符的解析功能。具体来说,-e选项可以将转义字符进行解析,并按照其特定的含义进行替换。
在给定的示例中,使用了转义字符\x2E来表示小数点"."。因此,当使用-e选项时,echo命令会将\x2E解析为".",从而在输出中显示小数点。
