stat -c %a file1

как скопировать пермишен одного файла другому?

Прикольная команда делает список файлов с числовым представлением пермишенов
for i in $(ls) ; do bla=$( stat -c “%a” $i);echo “$i: $bla”; done

Замена одной папку в пути на другую

Print current dir

List of directories

Make CD fs and burn it
mkisofs -r -o image.iso ivana_kupala/
sudo mkdir /mnt/iso
sudo mount -t iso9660 image.iso /mnt/iso -o loop
sudo umount /mnt/iso/
cdrecord -v -eject -dummy image.iso
cdrecord -v -eject image.iso

Make DVD
mkisofs -dvd-video -o /home/alexey/Download/karaoke.iso /home/alexey/Download/Karaoke/

isoinfo -i karaoke.iso-l

  1. Make an "ISO" filesystem image of a DVD filesystem:

    mkisofs -dvd-video dvd >dvd.iso

    dvd is the directory containing the filesystem produced by dvdauthor.

  2. Record "ISO" filesystem image to disc:

    growisofs -dvd-compat -Z /dev/dvd=dvd.iso

    The -Z option selects one-time recording or overwriting. growisofs can also record a new session (hence its name) but DVD videos must be recorded in a single session. The -dvd-compat option enables various recording features to improve compatibility.

  3. Record DVD filesystem directly to disc:

    growisofs -dvd-compat -Z /dev/dvd -dvd-video dvd
How to create ISO images from your HD CD DVD
To make an ISO from your CD/DVD, place the media in your drive but do not mount it. If it automounts, unmount it. (ubuntu automount so you need to unmount, that's quite easy, just choose the option unmount from the shell).

dd if=/dev/dvd of=dvd.iso # for dvd
dd if=/dev/cdrom of=cd.iso # for cdrom
dd if=/dev/scd0 of=cd.iso # if cdrom is scsi

To make an ISO from files on your hard drive, create a directory which holds the files you want. Then use the mkisofs command.

mkisofs -o /tmp/cd.iso /tmp/directory/

This results in a file called cd.iso in folder /tmp which contains all the files and directories in /tmp/directory/.

Упрощенной решение, позволяющее получить имя текущей папки:

pwd | awk '{print ("Dir is = " Name[split($0, Name, "/")])}'
