Welcome to the dark world where most IT people live

  • This is a gui free world
    • If you don't know what a gui is please quietly close the page and go buy a slurpee
    • If you don't know what a slurpee is we feel sorry for you.

Basic Commands

Changing Ownership

There are many ways to do this. Half of them may be more clever.

sudo chown walt:walt /path/to/filename

This will make the file filename belong to the user walt and the group walt. Usually we change the group and user at the same time.

OR

sudo chown user:group /path/to/directory/

This changes only the directory to user and group specified

Adding the -R flag after the chown will recurse into directories and files.

sudo chown -R . . .

  • We are not sure why the capital r is needed in some cases. But it is here.

Changing Permissions

This is very similar except we use chmod instead of chown

sudo chmod 644 /path/to/file or path/to/directory/

Adding the -R flag does the same as above.

Change all files recursively to 644

find /var/www/html/moodlecnx/ -type f -exec chmod 644 {} \;

Change all directories recursively to 755

find /var/www/html/moodlecnx/ -type d -exec chmod 755 {} \;

Mount and Unmount

iso files

sudo mkdir /mnt/iso sudo mount -o loop Win10_2004_English_x64.iso  /mnt/iso
