Create a false directory structure for testing your commands

You could avoid xargs and sed in this case (shorter command and less forking): At least bash and zsh have some mighty string modifiers. I would also suggest using find with exec option to get more flexibility. You may leave out or include "special" file for example.
This is sample output - yours may be different.

Ensure path permissions from '.' prior to root

`pwd` returns the current path `grep -o` prints each slash on new line perl generates the paths sequence: './.', './../.', ... `readlink` canonicalizes paths (it makes the things more transparent) `xargs -tn1` applies chmod for each of them. Each command applied is getting printed to STDERR. Show Sample Output

Recursively remove all empty directories

It starts in the current working directory. It removes the empty directory and its ancestors (unless the ancestor contains other elements than the empty directory itself). It will print a failure message for every directory that isn't empty. This command handles correctly directory names containing single or double quotes, spaces or newlines. If you do not want only to remove all the ancestors, just use: find . -empty -type d -print0 | xargs -0 rmdir
This is sample output - yours may be different.
0

find . -empty -type d -print0 | xargs -0 rmdir -p

Replicate a directory structure from a 'basedir' in a remote server.

The directories are created in the local host with the same structure below of a remote base directory, including the 'basedir' in case that it does not exists. You must replace user and remotehost (or IP address) with your proper values ssh will ask for the password of the user in remotehost, unless you had included properly your hostname in the remote .ssh/known_hosts file. Show Sample Output
This is sample output - yours may be different.
```
Password:
mkdir -p /var/opt/example

mkdir -p /var/opt/example/logs
