Operating Systems AIX Do you need execute permission to navigate to a directory? Post 302419399 by pludi on Friday 7th of May 2010 04:51:45 AM

Yes, he does need it.
  • Read permission = permission to list the contents of a directory, but not necessarily the files in in
  • Write permission = permission to create new entries in the directory (=create new files), but not necessarily modify the existing files
  • eXecute permission = permission to chdir to the directory, but not necessarily to run the files therein

Eg. with just the read permission he may do
Code:
ls TEST/*

With just the execute permission he may cd into it, but will never see any of the files in it.

NAME
rmdir, rm - remove (unlink) directories or files SYNOPSIS
rmdir dir ... rm [ -f ] [ -r ] [ -i ] [ - ] file ... DESCRIPTION
Rmdir removes entries for the named directories, which must be empty. Rm removes the entries for one or more files from a directory. If an entry was the last link to the file, the file is destroyed. Removal of a file requires write permission in its directory, but neither read nor write permission on the file itself. If a file has no write permission and the standard input is a terminal, its permissions are printed and a line is read from the standard input. If that line begins with `y' the file is deleted, otherwise the file remains. No questions are asked and no errors are reported when the -f (force) option is given. If a designated file is a directory, an error comment is printed unless the optional argument -r has been used. In that case, rm recur- sively deletes the entire contents of the specified directory, and the directory itself. If the -i (interactive) option is in effect, rm asks whether to delete each file, and, under -r, whether to examine each directory. The null option - indicates that all the arguments following it are to be treated as file names. This allows the specification of file names starting with a minus. SEE ALSO
