而不是将一串greps链接在一起并将它们传递给awk,请使用awk完成所有工作。在上面的例子中,如果一个字符串与pattern1 AND pattern2匹配,但不匹配pattern3,则会向stdout输出一个字符串。

$ 2,$ 3,$ 4字段是任意的,但请注意,第一个字段从$ 2开始,最后一个字段为$ NF-1。这是因为前导和尾随引号被视为字段分隔符。

为通道1和通道2解析给定csv文件的tektronic并将它们连接在一起。之后可以很容易地被gnuplot使用。

您可以使用多个字段分隔符分隔它们(=或)。例如,当您想要通过两个分隔符分割字符串时,这可能会很有帮助。#echo“one = two three”| awk -F“= |”{'print $ 1,$ 3'}一个三

与R的t()相同

linux命令:awk '{ for (f = 1; f <= NF; f++) a[NR, f] = $f } NF > nf { nf = NF } END { for (f = 1; f <= nf; f++) for (r = 1; r <= NR; r++) printf a[r, f] (r==NR ? RS : FS) }' }' FS) : RS ?

本示例计算“file.dat”的第一列和第二列的平均值。如果要对其他列进行平均,它可以很容易地修改。

我发现这非常适用于查看文件,寻找一块文本。有“grep -A#pattern file.txt”来查看模式后面的特定行数,但是如果要查看整个块,该怎么办?例如,“dmidecode”的输出(以root身份):dmidecode | awk'/ Battery /,/ ^ $ /'将显示电池组后面的所有内容,直到下一个文本块。同样,当我想根据模式查看整个文本块时,我发现这非常有用,并且我不关心在输出中看到其余的数据。这可以用于Unix上的'/ etc / securetty / user'文件以查找特定用户的块。它可以用来对付Apache上的VirtualHosts或Directories来查找特定的定义。这些场景继续以任何方式格式化的文本。非常便利。

此命令将通过将输出重定向到单独的.txt文件来对FILENAME的内容进行排序,其中第三列将用于排序。如果FILENAME的内容如下:foo foo一个foobar栏B barlorem ipsum一个lorem然后创建两个名为A.txt和B.txt的文件,它们的内容将是:A.txtfoo foo a foolorem ipsum A loremand B.txt将bebar酒吧B酒吧

我在这个网站上找到的一个脚本的变体,然后缩小到只使用awk。它显示所有试图登录到该框但使用SSH失败的用户。将其管理到sort命令以查看哪些用户名登录失败最多。

将FILE替换为文件名(或 - 对于stdin)。

只要它们发生了一定次数(在这种情况下为500),就会从日志中打印引用者的摘要。 grep命令排除了术语,我添加了这个命令来删除我不感兴趣的结果。

有时候,紧张的数据会隐藏趋势,执行滚动平均可以提供更清晰的视图。
