文件中有很多行还有更多行,但我猜这已经足够了。现在我需要提取 Business Name 列中的信息。所以我尝试了:
sed -n '^[^,]*,{1}p' $1
其中 $1 是从用户输入读取的文件名。我也试过:
sed -n '\^\[\^,\]*,{1}p' $1
我更熟悉 grep RE,这就是为什么它们看起来像 grep RE 而不是 sed 的原因。最近才开始使用 sed。
对于这样一个简单的任务,甚至
awk
看起来有点矫枉过正——你可以使用cut
:如果您必须使用
sed
,那么最简单的方法可能是匹配第一个逗号和之后的所有内容,并将其替换为空:或者
如果您想从输出中排除任何不包含匹配项的行(即不包含至少一个逗号的行)。
如果您决定通过显式匹配第一列内容来做到这一点,那么要么
或(使用扩展正则表达式)
和以前
-n
一样p
可选。如果您打算
{1}
成为量词,请注意,在基本正则表达式中,大括号也需要转义\{1\}
- 但是您不需要显式量词来匹配某事的一次出现。如果您愿意,您可以在模式的开头添加一个^
锚点,但我认为这里不需要它。
