pushd dir1 pushd ../dir2 pushd /full/path/to/dir3 # There are now three directories in the stack. pushd ~3 pushd ~2 # The same three directories are still on the stack, # just in a different order. I use popd rarely, only when I want to remove a directory from the stack when I know I'm done using that directory.

Apr 3, 2016 · Is there a difference between the behavior of pushd/popd in bash vs zsh? It seems in zsh cd, cd- behaves exactly the same as pushd/popd (which adds/pops directory automatically when cd) while in bash cd doesn't affect the dir stack. If someone can give me a …

Mar 14, 2018 · pushd and popd are a pair of tools that work with a data structure known as a "stack". Picture a spring-loaded dispenser, like a Pez dispenser . If you push an item onto a stack, you are storing it for later use, like pushing one 'pill' into the top of the Pez dispenser.

pushd/popd are easier to read but they are not safe because if script is interrupted (normally or forcefully) in between, you will endup with an altered CWD. When using subshell there is a guarantee that at the end, you will have the original CWD, regardless how the execution happens.

The first method is exactly what I wanted. The second wouldn't work in my case since I had called pushd a few times, then removed one of the directories in the middle, then popd was failing when I tried to unroll. I needed to jump over all the buggered up stuff in the middle to get back to where I …

What's a way to make this execute in the shell terminal? #!/bin/sh pushd $1 time What I really want to accomplish is invoke pushd followed by other-command with one command.

At the same time I like pushd . and popd. However, when I want to remember the current working directory by means of pushd ., I lose the possibility to go to the previous directory by cd -. (As pushd . also performs cd .). How can I use pushd to still be able to use cd - By the way: GNU bash, version 4.1.7(1)

Jan 7, 2020 · In Bash, the dirs command clears or shows the stack in various ways, popd removes any specified dir, and pushd adds a dir or rotates the stack to change to any of the dirs already stored. The pushd stack is not "cleared" as such. Pushd is a shell built-in, not an external command (which would not be able to change the shell's own environment).

Dec 11, 2019 · $ cd /tmp $ echo 'pushd /etc' > experiment.sh $ bash experiment.sh /etc /tmp $ pwd /tmp $ Above, experiment.sh is the poorly-written script. It uses pushd to push the current directory on the stack and switch to /etc/ then terminates. After the script terminated, the running shell was still in /tmp.
