2.1 pwd

https://www.computerhope.com/unix/upwd.htm

bash-4.4# pwd
/Ada/.simageviewtrainer/rotate/toClassify

每个运行中的进程，都有一个对应的当前工作目录。

当你在终端中启动其它程序以产生对应的进程时，该进程默认会继承终端进程的当前工作目录。在进程中打开或读取以相对路径指定的文件名时，就会以当前工作目录为基准，解析出相对路径的文件名所对应的绝对路径，再确定对应的文件是否存在。

日常使用过程中，某些软件会报告某某文件找不到，其中一个可能的原因就是，进程的当前工作目录不正确，导致某些以相对路径指定的文件无法找到，此时就需要使用pwd命令来显示出当前工作目录，以确定或排除这种可能原因。
