This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.














  • @JeffSchaller the linked question indicates that A pathname that begins with two successive slashes may be interpreted in an implementation-defined manner, although more than two leading slashes shall be treated as a single slash. I am still curious as to why Linux implements in this way. Why the complexity of special behaviour? Only because it is permitted by the standard? Are there any non-obvious differences between the / and // directory?

  • an ls -lid / // would probably show the same inode --> the same directory. Per the linked duplicate, There is one exception: if a pathname starts with exactly two slashes, it may be treated differently (ref: base definitions §4.11 pathname resolution). Linux itself doesn't do this
