This question already has an answer here:
Is there ever a benefit to preceding a path with
./ (dot slash)?
In most cases,
cd ./home is equivalent to
cd home (and also
cd ./././././home). Is there ever a case where these two paths would NOT evaluate to the same path? Is there some benefit or drawback to either having or NOT having
./ at the beginning of a folder or file path?
What if from inside a program or script, I wanted open a config file, i'm hard coding a file to open, should it be:
Does POSIX (or common Unix implementations) give any semantic difference between opening these two paths?
