[英]Find file that match patterns located in different lines
I'm doing a program that can find a file(s) that match two patterns given by the user (Date and ID), both patterns are located in different lines inside every file. 我正在做一个程序,该程序可以找到与用户指定的两种模式(日期和ID)匹配的文件,两种模式都位于每个文件的不同行中。 The files are located in different .zip sub folders. 这些文件位于不同的.zip子文件夹中。 My code is not working and I'm trying to use PCRE DOTALL. 我的代码不起作用,我正在尝试使用PCRE DOTALL。
File Sample: 文件样本:
TextTextTextTextText
TextTextText: [20-MAY-2017]
TextTextTextTextText
TextTextTextTextText
TextTextTextTextText
TextTextText: [123456]
Code I'm using: 我正在使用的代码:
echo "Set a specific Date [ DD-MM-YYYY ]: "
read -r Date
echo -e "Introduce ID: "
read -r ID
#Search pattern
grep -Pzo '(?s)$Date.*\n.*$ID' .
You can't use variables in single quoted strings. 您不能在单引号字符串中使用变量。 Try this out: 试试看:
#!/bin/bash
read -r -p "Set a specific Date [ DD-MMM-YYYY ]: " searchdate
read -r -p "Introduce ID: " searchid
grep -Pzo "(?s)\[$searchdate\].*\[$searchid\]" sample.txt
Provided your input doesn't have a /
character in it, you could also use the simpler awk command: 如果您的输入中没有/
字符,则还可以使用更简单的awk命令:
awk "/$searchdate/,/$searchid/" sample.txt
