Question

我有一个包含以下内容的文件：

/home/adversion/web/wp-content/plugins/akismet/index1.php: PHP.Mailer-7 FOUND
/home/beckydodman/web/oldshop/images/google68274020601e.php: Trojan.PHP-1 FOUND
/home/resurgence/web/Issue 272/Batch 2 for Helen/keynote_Philip Baldwin (author revise).doc: W97M.Thus.A FOUND
/home/resurgence/web/Issue 272/from Helen/M keynote_Philip Baldwin.doc: W97M.Thus.A FOUND
/home/skda/web/clients/sandbox/wp-content/themes/editorial/cache/external_dc8e1cb5bf0392f054e59734fa15469b.php: Trojan.PHP-58 FOUND

我需要通过删除冒号（:）之后的所有内容来清理此文件。

所以它看起来像这样：

/home/adversion/web/wp-content/plugins/akismet/index1.php
/home/beckydodman/web/oldshop/images/google68274020601e.php
/home/resurgence/web/Issue 272/Batch 2 for Helen/keynote_Philip Baldwin (author revise).doc
/home/resurgence/web/Issue 272/from Helen/M keynote_Philip Baldwin.doc
/home/skda/web/clients/sandbox/wp-content/themes/editorial/cache/external_dc8e1cb5bf0392f054e59734fa15469b.php

Answer 1

使用awk：

$ awk -F: '{print $1}' input
/home/adversion/web/wp-content/plugins/akismet/index1.php
/home/beckydodman/web/oldshop/images/google68274020601e.php
/home/resurgence/web/Issue 272/Batch 2 for Helen/keynote_Philip Baldwin (author revise).doc
/home/resurgence/web/Issue 272/from Helen/M keynote_Philip Baldwin.doc
/home/skda/web/clients/sandbox/wp-content/themes/editorial/cache/external_dc8e1cb5bf0392f054e59734fa15469b.php

或cut

$ cut -d: -f1 input

或sed

$ sed 's/:.*$//' input

在awk-mode中

或perl

$ perl -F: -lane 'print $F[0]' input

最后，纯bash

#!/bin/bash

while read line
do
    echo ${line%%:*}
done < input

Answer 2

这应该足够了

awk -F: '{print $1}' file-name

Answer 3

这里没有sed / awk解决方案

 cut -d : -f 1 [filename]

Answer 4

通过sed管道：

$ echo "/home/adversion/web/wp-content/plugins/akismet/index1.php: PHP.Mailer-7 FOUND" | sed 's/: .*$//'

/home/adversion/web/wp-content/plugins/akismet/index1.php

只要': '没有出现两次，就会有效。请注意，上面的awk / cut示例更有可能失败，因为它们匹配'：'不是'：'

匹配后删除文件中的文本
