java 正则匹配空格字符串 正则表达式截取字符串 需求:从一堆sql中取出某些特定字符串: 比如配置的sql语句为:"company_code = @cc and project_id = @pid ; update t set a = @aa,b=@bb,c=@cd,ttt=@ttt;update t2 set d=@bb"; 我要拿出所有的以@开头的作为变量,并且去重,则如下玩: ps:其中正则匹配空格是 “\s+” public class Test { public stat
Shell查看文件的最后5行,并对每行进行正则匹配,代码如下: #!/bin/sh pattern="HeartBeat" /home/test/log/log_20150205.log | while read line do if [[ $line =~ $pattern ]] then echo "Match" else echo "No match" fi echo $line done
