搜索带有特殊字符的字符串 linux

您可以grep在文件/变量上运行以下命令。

grep -oP '(?<=\[c8d313c81caa1103:-603ec52f:1630466b4e8:5448]\[amirbekova] com\.sas\.analytics\.crm\.custdata\.sql)(.*)(?=quit;)' ~/test_awk/input_file

说明：

• -oP -o仅将匹配的正则表达式显示为输出，而不是整行，并-P激活 perl 正则表达式以进行后视/前瞻，...

• 以下正则表达式(?<=\[c8d313c81caa1103:-603ec52f:1630466b4e8:5448]\[amirbekova] com\.sas\.analytics\.crm\.custdata\.sql)(.*)(?=quit;)匹配您的模式：演示：https : //regex101.com/r/FFrCu3/1/和关于正则表达式的解释：http : //www.rexegg.com/regex-quickstart.html

演示：

$ cat ~/test_awk/input_file
[c8d313c81caa1103:-603ec52f:1630466b4e8:5448][amirbekova] com.sas.analytics.crm.custdata.sql - TID[25810F8F] amirbekova----- Execute Sql in MAIQService.execute() ----- PROC SQL; Create table MATables.TXIDFAEAIZ5BDSAAGamirbekova as SELECT DISTINCT table0.DWH_ID AS DWH_ID LABEL='Идентификатор клиента в КИХ' FORMAT=$40. FROM CMDM.INDIVIDUAL_OBLIGATIONS table2 Left join CMDM.SYS_DICT_BINARY table1 on ( ( (table2.IO_ACTIVE_SIGN=table1.ID)) ) Right join CMDM.CLIENT table0 on ( ( (table0.DWH_ID=table2.CLIENT _DWH_ID)) ) quit;

$ grep -oP '(?<=\[c8d313c81caa1103:-603ec52f:1630466b4e8:5448]\[amirbekova] com\.sas\.analytics\.crm\.custdata\.sql)(.*)(?=quit;)' ~/test_awk/input_file

如果您的模式在多行上，那么您可以使用以下awk命令：

awk '/^\[c8d313c81caa1103:-603ec52f:1630466b4e8:5448\]\[amirbekova\] com.sas.analytics.crm.custdata.sql/{flag=1;print $NF;next}/^quit;/{flag=0;}{if(flag){print}}' input_file
