NAME
dir - format of directories on short-name HFS file systems SYNOPSIS
Remarks This entry describes the System V-compatible directory format for the HFS file system. It is provided strictly for backward compatibility and compatibility with applications expecting a System V file system environment. It is not compatible with the similar but more general HFS directory format in which describes a format identical to that used in an HFS file system supporting long file names up to 255 bytes in length. The structure defined in should be used in conjunction with the directory(3C) routines for portability to other industry UNIX implementa- tions. DESCRIPTION
A directory behaves exactly like an ordinary file, except that no user can write into a directory. The structure of a directory entry as given in the header file is: By convention, the first two entries in each directory are for and (``dot'' and ``dot dot''). The first is an entry for the directory itself. The second is for the parent directory. The meaning of is modified for the root directory of the master file system; there is no parent, so and have the same meaning. AUTHOR

NAME
convertfs - convert an HFS file system to allow long file names SYNOPSIS
[special-file] DESCRIPTION
The command converts an existing HFS file system supporting the default maximum file name length of 14 characters into one that supports file names up to 255 characters long. Once an HFS file system is converted to long file names, it cannot be restored to its original state, since the longer file names require a directory representation that is incompatible with the default HFS directory format. Since this is an irreversible operation, prompts for verification before it performs a conversion. forces the system to reboot if the root file system is converted. When converting the root file system, the system should be in single- user mode, with all unnecessary processes terminated and all non-root file systems unmounted. Except for the root file system, requires that the file system to be converted be unmounted. If invoked without arguments, interactively prompts the user with a list of the HFS file systems from One or more or all of the listed file systems can be selected for conversion. Typically, it is desirable to convert all of the file systems in to avoid inconsistencies between two file systems mounted on the same system. can also be invoked with an argument of either a block or character special-file name for a file system to be converted. Only the block special file should be specified for a mounted root file system. As part of the conversion process, performs an on each file system (see fsck(1M)). Options Do it quietly. will perform the conversions without querying the user. Normally prompts the user before converting a file system. RETURN VALUE
returns the following values: Success. Either successfully converted the file system, or the file system already allowed long file names. Failure. was not able to convert the file system due to some failure in processing. AUTHOR
