刪除文件中的文本匹配

Question

後，我有以下文件：

/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 

我需要用冒號（:）之後，除去一切清理這個文件了。

，使它看起來像這樣：

/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

這應該足以

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

Answer 2

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 

sed或

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

或perl在AWK模式

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

最後，純bash

#!/bin/bash 

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

Answer 3

這裏一個無SED/AWK溶液

cut -d : -f 1 [filename] 

Answer 4

管通過sed：

$ 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

將工作，只要': '不會出現兩次。請注意，以上示例的awk/cut更可能因符合'：'not'而失敗：'
