linux - egrep 没有得到结果

Question

我写了一个小脚本，它将egrep服务器日志中的两个模式

pattern - 'Unable to resolve location classpath:db/migration|Processing PersistenceUnitInfo'

代码片段

#/bin/sh
ssh  tomcat@x.x.x.x egrep -e 'Unable to resolve location classpath:db/migration|Processing PersistenceUnitInfo' /usr/local/dd/logs/ddservice.log

执行结果

bash: Processing: command not found
grep: to: No such file or directory
grep: resolve: No such file or directory
grep: location: No such file or directory
grep: classpath:db/migration: No such file or directory

事实上，属于上述模式的关键字很少。我如何修改脚本以获取模式。

Answer 1

您必须在搜索的字符串中使用 \ 转义空格。

尝试

ssh tomcat@x.x.x.x egrep -e 'Unable\ to\ resolve\ location\classpath\:db/migration|Processing\ PersistenceUnitInfo' /usr/local/dd/logs/ddservice.log
