+## Workings of file permissions
+
+### Change permissions
+To change file permissions use `chmod (-R) XXX (path)`  
+
+XXX signify the permissions for the file's owner/group/others respectively  
+
+Each X goes from 0 to 7.  
+What each number means can be easily calculated by looking at what the individual bit values mean.  
+```
+0 -> No Permission
+4 -> Read Permission
+2 -> Write Permission
+1 -> Execute Permission
+```
+
+A value of 5 therefor gives the permissions "Read" and "Execute".  
+
+*To enter a folder, you need the read as well as the execute permission!*  
+
+### Change user and group
+Use `chown` to change the owner and group of a file or directory.  
+
+Example:  
+`chown (-R) (owner):(group) (path)`  
+
+### Change group
+Use `chgrp` to change the group of a file or directory.  
+
+Example:  
+`chgrp (-R) (group) (path)`  
+
+## Find biggest files
+`find . -type f -print0 | xargs -0 du -s | sort -n | tail -(amount) | cut -f2 | xargs -I{} du -sh {}`  
+
+`find . -type f -printf "%s %p\n" | sort -nr | head -5`
