原因是脚本中正则里的符号问题，在if中不好处理。最好是先把这个正则定义成一个变量，然后在if中引用，如下 regex_line="^java\.library\.path=(.*)$"...if [[ $line =~ "$regex_line" ]]; then...字符串最好加双引号，改为下面这样试试：if [[ “$line” =~ “^java\.library\....

The conditional ends with esac. 脚本将$1与用字符)分隔的每个case值进行匹配。 如果一个case值与$1匹配,shell将执行case下面的命令,直到遇到;;,然后跳转到esac关键字。 条件以esac结束。 For each case value, you can match a single string (like bye in the preceding example) or multiple strings with...
