我在ubuntu终端 中想启动karaf，通过find也找到了karaf
root@stu-virtual-machine:/home/stu# find . -name karaf
./.m2/repository/org/apache/karaf
./.m2/repository/org/apache/karaf/karaf
但我输入.karaf，无法运行，如下所示
root@stu-virtual-machine:/home/stu/.m2/repository/org/apache/karaf# .karaf
.karaf：未找到命令
root@stu-virtual-machine:/home/stu/.m2/repository/org/apache/karaf#
root@stu-virtual-machine:/home/stu/.m2/repository/org/apache/karaf# cd ./karaf
root@stu-virtual-machine:/home/stu/.m2/repository/org/apache/karaf/karaf# .karaf.karaf：未找到命令
root@stu-virtual-machine:/home/stu/.m2/repository/org/apache/karaf/karaf#
是我哪里有错吗？求大神指导
