grep 匹配多个子字符串并在丢失时通过或失败

grep 匹配多个子字符串并在丢失时通过或失败

我有一个

nginx -V 2>&1 | \
grep -qi 'nginx/1.9.10\|ngx_pagespeed-release-1.9.32.10\|openssl-1.0.2f\|modsecurity-2.9.‌​0' \
&& echo "has the stuff we need" \
|| echo "missing something"

这与

[root@mage2appblock vagrant]# nginx -V
nginx version: nginx/1.9.10

似乎如果我改变子字符串

'nginx/1.9.10\|ngx_pagespeed-release-1.9.32.10\|openssl-1.0.2f\|modsecurity-2.9.‌​0'

'nginx/1.9.10\|ngx_pagespeed-release-1.9.32.10\|openssl-1.0.2f\|modsecurity-2.9.‌​1'

"has the stuff we need"尽管并非所有内容都存在,但我仍然明白。我需要全部匹配或全部不匹配。

答案1

awk '/openssl-1.0.2f/ {test1=1} /nginx\/1.9.10/ {test2=1} 
  END { if (test1 && test2) print "has the stuff we need"; 
  else print "missing something"}'

awk如果需要,您还可以设置退出代码。

更新

较短版本(假设输入确实包含 0x1 个字符,则将带有换行符的输入视为单个“行”)

awk -v RS='\1' '/openssl-1\.0\.2f/ && /nginx\/1\.9\.10/ {
 print "has the stuff we need"; exit};{print "missing something"; exit(1)}'

答案2

稍作修改即可工作:

[ $(nginx -V 2>&1 | 
    grep -cFf <(
        echo 'nginx/1.9.10
ngx_pagespeed-release-1.9.32.10
openssl-1.0.2f
modsecurity-2.9.0'
    )) -eq 4 ] &&
echo "has the stuff we need" ||
echo "missing something"

答案3

只需使用perl并读取整个文件:

nginx -V 2>&1 | perl -0ne 'print "found\n" if m#nginx/1.9.10# && 
      /ngx_pagespeed-release-1.9.32.10/ && 
     /openssl-1.0.2f/ && /modsecurity-2.9.0/'

另请注意,问题文本中有一些隐藏字符。我不知道这些是否也存在于您的实际搜索字符串中,但是如果存在,它们会给您带来问题。如果我从你的问题中复制modsecurity-2.9.‌​0并传递它od -c,我会得到:

$ echo modsecurity-2.9.‌​0 | od -c
0000000   m   o   d   s   e   c   u   r   i   t   y   -   2   .   9   .
0000020 342 200 214 342 200 213   0  \n
0000030

具体来说,根据uniprops,您出现了 6 次U+FFFD <�> \N{替换字符}最后一个.和最后一个之间0

答案4

has_all_iregexps() {
  awk '
    BEGIN {
      if (ARGC <= 1) exit
      for (i = 1; i < ARGC; i++) s[tolower(ARGV[i])]
      n = ARGC - 1
      ARGC = 1
    }
    {
      for (i in s) if (tolower($0) ~ i) {
        delete s[i]; if (!--n) exit
      }
    }
    END {
      if (n) {
        print "Those regexps were not matched:"
        for (i in s) print "  " i
        exit(1)
      }
    }' "$@" >&2
}

进而:

nginx -V 2>&1 |
  has_all_iregexps 'nginx/1\.9\.10' \
                   'ngx_pagespeed-release-1\.9\.32\.10' \
                   'openssl-1\.0\.2f' \
                   'modsecurity-2\.9\.‌​0' &&
  echo "has the stuff we need"

或者:

has_all_istrings() {
  awk '
    BEGIN {
      if (ARGC <= 1) exit
      for (i = 1; i < ARGC; i++) s[tolower(ARGV[i])]
      n = ARGC - 1
      ARGC = 1
    }
    {
      for (i in s) if (index(tolower($0), i)) {
        delete s[i]; if (!--n) exit
      }
    }
    END {
      if (n) {
        print "Those strings were not found:"
        for (i in s) print "  " i
        exit(1)
      }
    }' "$@" >&2
}

nginx -V 2>&1 |
  has_all_istrings 'nginx/1.9.10' \
                   'ngx_pagespeed-release-1.9.32.10' \
                   'openssl-1.0.2f' \
                   'modsecurity-2.9.‌​0' &&
  echo "has the stuff we need"

tolowers 用于不区分大小写的匹配,以匹配您对 的使用-i,尽管我不确定您为什么要在这里进行不区分大小写的匹配)。
