    This means user applications iterating over and opening files in a large directory would thus generate many more disk seeks between non-adjacent files—a notable performance drain in other file systems with hash-ordered directories such as ReiserFS, [81] ext3 (with Htree-indexes enabled [82]) and ext4, all of which have TEA-hashed filenames.

    The pushd ('push directory') command saves the current working directory to the stack then changes the working directory to the new path input by the user.

    Bash executes these files as part of its standard initialization, but other startup files can read them in a different order than the documented Bash startup sequence. The default content of the root user's files may also have issues, as well as the skeleton files the system provides to new user accounts upon setup.
