Equivalent of Shell 'Cd' Command to Change the Working Directory

Equivalent of shell 'cd' command to change the working directory?

You can change the working directory with:

import os

os.chdir(path)

There are two best practices to follow when using this method:

1. Catch the exception (WindowsError, OSError) on invalid path. If the exception is thrown, do not perform any recursive operations, especially destructive ones. They will operate on the old path and not the new one.
2. Return to your old directory when you're done. This can be done in an exception-safe manner by wrapping your chdir call in a context manager, like Brian M. Hunt did in his answer.

Changing the current working directory in a subprocess does not change the current working directory in the parent process. This is true of the Python interpreter as well. You cannot use os.chdir() to change the CWD of the calling process.

How to cd between directories using a python script

To change working directory of use

os.chdir("/your/path/here")

subprocess will spawn new process and this doesn't affect your parent.

Change current directory and view available directories

import os

os.chdir('folder1')

or

os.chdir('folderinfolder1')

Temporarily change current working directory in bash to run a command

You can run the cd and the executable in a subshell by enclosing the command line in a pair of parentheses:

(cd SOME_PATH && exec_some_command)

Demo:

$ pwd
/home/abhijit
$ (cd /tmp && pwd)  # directory changed in the subshell
/tmp 
$ pwd               # parent shell's pwd is still the same
/home/abhijit

Why can't I change directories using cd in a script?

Shell scripts are run inside a subshell, and each subshell has its own concept of what the current directory is. The cd succeeds, but as soon as the subshell exits, you're back in the interactive shell and nothing ever changed there.

One way to get around this is to use an alias instead:

alias proj="cd /home/tree/projects/java"

Change directory in a server without leaving the working directory

You can store the default path as a kind of root path and path.join(root, client_path) this way you have a complete path that has to start with C:\test1

The issue you have to overcome is deciding if you have to join the current path or the root path with the client's command. I would first check if the directory exists in the current working directory if not I would try finding it in the "root" path

How can I set the current working directory to the directory of the script in Bash?

#!/bin/bash
cd "$(dirname "$0")"
