grep/sed+；精确匹配复线

我有档案：

  # more file
  (WORD = (TCPIP = (PROTOCOL = TCP)(WORD = ALIAS_NAME)(PORT = 10234))

但是当我尝试匹配文件中的部分行（由grep-w）时，grep也会匹配该行（尽管这是整行的一部分）

我的问题是如何精确匹配文件中的行

所以，如果我使用grep或其他类似sed/awk的东西，它将只匹配整行

通过返回整行，grep只是表示is在该行中找到了字符串。如果只想在命令行上查看匹配的文本，可以（例如）使用-o（仅匹配）：

为了查看CL上的结果，请省略“echo$name |”

如果要捕获变量中的确切文本，可以执行以下操作：

name=`grep -o "(WORD = (TCPIP = (PROTOCOL = TCP)(WORD = ALIAS_NAME)(PORT = 10234))" /Users/deveritt/Desktop/test.html`
echo $name
(WORD = (TCPIP = (PROTOCOL = TCP)(WORD = ALIAS_NAME)(PORT = 10234))

…或将第二个示例与反勾号一起使用`

echo $name | grep -o "(WORD = (TCPIP = (PROTOCOL = TCP)(WORD = ALIAS_NAME)(PORT = 10234))"

name=`grep -o "(WORD = (TCPIP = (PROTOCOL = TCP)(WORD = ALIAS_NAME)(PORT = 10234))" /Users/deveritt/Desktop/test.html`
echo $name
(WORD = (TCPIP = (PROTOCOL = TCP)(WORD = ALIAS_NAME)(PORT = 10234))
