Le ficher output.pdf enregistré au même endroit que les fichiers sources sera le résultat de l’opération.
Pour créer un PDF avec les pages 1, 2, 4 et 5 d’un PDF de plusieurs pages :
$ pdftk myoldfile.pdf cat 1 2 4 5 output mynewfile.pdf
Note
les options cat et output sont spécifiques à pdftk :
Pour préciser une page range :
$ pdftk myoldfile.pdf cat 1-2 4-5 output mynewfile.pdf
Pour splitter chaque page en un fichier pdf spécifique :
$ pdftk myoldfile.pdf burst
Par défaut les fichiers seront nommés pg_0001.pdf, pg_0002.pdf, etc.

The following script will take all *.mkv files within your selected folder and move them into a folder based on their name. Note that this does not go into subfolders within the starting/selected folder.
cd /path/to/your/movies/files/
find . -maxdepth 1 -type f -iname "*.mkv" -exec sh -c 'mkdir "${1%.*}" ; mv "${1%}" "${1%.*}" ' _ {} \;
for %i in (*) do md "%~ni"
This will create a folder for every file in the directory.
for %i in (*) do move "%i" "%~ni"
This will move all of your files into the new directories.
If you need to clean up empty directories, this command will do that:
for /f "usebackq delims=" %d in ("dir /ad/b/s | sort /R") do rd "%d"
Alternatively in Windows you can run the following script in Powershell to iterate over each file in a directory, and move it to a folder with the same name.
Get-ChildItem -File
| ForEach-Object {
$dir = New-Item -ItemType Directory -Name $_.BaseName -Force
$_ | Move-Item -Destination $dir
}
Delete folders recursively:
find /path/to/source/ -name 'nameOfTheDirectory' -exec rm -rf {} \;
This will do it recursively for you:
find /path/to/base/dir/* -type d -ctime +10 -exec rm -rf {} \;
