Re: what is the diff b/w a file and a dir in Unix
^^ u studying unix for internals ??
which college ??
tom i hv unix internals !
and there is no diff b/w file and dir
everything in unix is file
ok am not sure am unix newb but this is my imagination !!
dir is some special file
i think it points to location of files to which it is supposed to point at
means the files in it....which again will be there somewhere in hdd
but this dir file stores what files to list when its opened

^^ What the hell???
I am correct in believing, from the post above, that Unix and Linux are from 2 different planets?

Re: what is the diff b/w a file and a dir in Unix
hey m not asking is linux is unix or not???...
what i meant to ask was....is there ne diff in files and dirs in unix???...
u may find that everything is a file, if u read the books..
but what i have seen is...
by default...dir have a permission of 755 and files have 644..
if everything is file in unix then why a variation in the permission..
if u see dirs have a slash after there name but files do not have...
please try to find out little more diff if any...
i din't have any internals but i jus wanna know...
