1.找出字符串里的数字
"abc34325sad" --->34325
Matcher m=Pattern.compile("\\d+").matcher("于修订版 19842"); while(m.find()){ System.out.print(m.group()+""); }
result:
19842
grep 支持正则表达式搜索
grep '[0-9]\{4,\}' /tmp/a.txt 搜索有至少4个连续数字的行
grep 'RoleCache长度=[0-9]\{4,\}' /tmp/a.txt 搜索有至少4个连续数字的行
搜索中文
双引号中文字懒惰匹配
".*[\u4e00-\u9fa5]+.*?"
单引号中文字懒惰匹配
'.*[\u4e00-\u9fa5]+.*?'
grep 'num=7[0-9]\{4,\}' /data/log/logger/logger.2014-11-*
搜索出带有num=7前缀的后面连续4个数字的日志
