Linux Alternative switching path mode pushd and POPD

PUSHD switch to the specified path
POPD back to the last directory
======================================
PUSHD can switch to the path specified later,Accumulate stack directories by the way
Stack: This is called a stack of pushd-accumulating directories
[Email protected] etc]# pushd/etc/sysconfig/network-scripts/
/etc/sysconfig/network-scripts/etcThese two directories are cumulative stacks

Accumulate a stack directory again/test
[Email protected] network-scripts]# pushd/test/
/test/etc/sysconfig/network-scripts/etc

Dirs can view the stack directory that is currently accumulating, or you can empty the stack with dirs-c
[Email protected] test]# dirs
/test/etc/sysconfig/network-scripts/etc

Each time the pushd switches to the 2nd directory in the Stack
[Email protected] etc]# pushd
/test/etc/etc/sysconfig/network-scripts

You can pushd +1 to move the stack directory forward, by the way into the back row in the first directory
[Email protected] etc]# pushd +1
/etc/sysconfig/network-scripts/test/etc

You can add more numbers to move more directories:
[Email protected] network-scripts]# pushd +2
/etc/etc/sysconfig/network-scripts/test

======================================
POPD back to the last directory you went to.

======================================

In the actual application of the popd and pushd commands, it comes in handy when writing shell scripts-you don't have to remember where you came from, and as long as you execute popd, you can go back to your directory.
