pwd命令主要用于查看当前工作目录的完整路径。
主要用法：pwd [option]
常用范例：
1.查看当前完整路径
命令：pwd
输出：
[root@localhost ~]# pwd /root [root@localhost ~]#
2.查看链接路径
命令：pwd -P
输出：
[root@localhost soft]# cd /etc/init.d [root@localhost init.d]# pwd /etc/init.d [root@localhost init.d]# pwd -P /etc/rc.d/init.d
特性：当前目录被删除了，而pwd命令仍然显示那个目录
[root@localhost init.d]# cd /opt/soft [root@localhost soft]# mkdir removed [root@localhost soft]# cd removed/ [root@localhost removed]# pwd /opt/soft/removed [root@localhost removed]# rm ../removed -rf [root@localhost removed]# pwd /opt/soft/removed [root@localhost removed]# /bin/pwd /bin/pwd: couldn't find directory entry in “..” with matching i-node [root@localhost removed]# cd [root@localhost ~]# pwd /root [root@localhost ~]#
