Linux中pwd命令来查看”当前工作目录”的完整路径.简单的说,每当你在终端进行操作时,你都会有一个当前工作目录.在不太确定当前位置时,同样可以使用pwd来判定当前目录在文件系统内的确切位置.
命令格式: pwd [option]
命令功能: 查看”当前工作目录”的完整路径
常用实例:
<1>查看当前工作目录的完整路径
命令: pwd
eg:
[root@sqj ~]# pwd
/root
<2>显示实际路径,而非使用链接(link)路径
命令: pwd -P
eg:
[root@sqj init.d]# pwd
/etc/init.d
[root@sqj init.d]# pwd -P
/etc/rc.d/init.d
<3>/bin/pwd
命令: /bin/pwd [option]
参数:
-L 目录连接链接时,输出连接路径
-P 输出物理路径
eg:
[root@sqj init.d]# pwd
/etc/init.d
[root@sqj init.d]# /bin/pwd
/etc/rc.d/init.d
[root@sqj init.d]# /bin/pwd -L
/etc/init.d
[root@sqj init.d]# /bin/pwd -P
/etc/rc.d/init.d
<4>当前目录被删除了,而pwd命令仍然显示那个目录
[root@sqj test]# pwd
/home/test
[root@sqj test]# rm ../test -rf
[root@sqj test]# pwd
/home/test
[root@sqj test]# cd ..
[root@sqj home]# ls
sqj
