الصلاحيات في لينكس
التوصل إلى فهم أعمق لكيفية عمل نظام التشغيل مع الصلاحيات وكيف يتم تطبيق الأرقام والصلاحيات التي توفرها من القراءة / الكتابة / التنفيذ .
وهذه الارقام متمثلة وتترواح بين 0-7.
ويبين الجدول التالي ما يمثله كل رقم
Permission bits – Output text – Numbered value
All types of access are denied = 0
Execute access is allowed only = 1
write access is allowed only = 2
write and execute access are allowed = 3
read access is allowed only = 4

Linux Permissions
To get a deeper understanding of how the operating system interprets the permissions we have to dig into how bit numbers represent the read/write/execute permissions. The bits are as mentioned before represented by numbers ranging from 0-7. The table below shows what each number represents.
