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
mkdir -p /var/opt/example/sent

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Find the package that installed a command

sort the output of the 'du' command by largest first, using human readable output.

In this case I'm just grabbing the next level of subdirectories (and same level regular files) with the --max-depth=1 flag. leaving out that flag will just give you finer resolution. Note that you have to use the -h switch with both 'du' and with 'sort.'

Alias for getting OpenPGP keys for Launchpad PPAs on Ubuntu

Makes it easy to add keys to new ppa sources entries in apt sources.list Now to add the key for the chromium-daily ppa: $ launchpadkey 4E5E17B5

check open ports without netstat or lsof

Trick find -exec option to execute alias

An alias cannot be executed as command in a find -exec line. This form will trick the command line and let you do the job.

Get full directory path of a script regardless of where it is run from

Also resolves symlinks, showing the full path of the link target

grep apache access.log and list IP's by hits and date - sorted

Remove security limitations from PDF documents using QPDF

Remove security restrictions from PDF documents using this very simple command on Linux and OSX. You need QPDF installed (http://qpdf.sourceforge.net/) for this to work.

Dump audio from video without re-encoding.

This removes the video and subsequent file size and directly copies the audio.

list all files in a directory, sorted in reverse order by modification time, use file descriptors.

It's both silly, and infinitely useful. Especially useful in logfile directories where you want to know what file is being updated while troubleshooting.
