The Missing AIX Documentation Project
Welcome to
AIX - All Intricacies eXplained
List of AIX commands lacking documentation:
- mkinstallp (create installable packages)
- imfs (create FS entries in /etc/filesystems)
- getlvodm (get LVM information from LVCB and ODM)
- ldeletepv (delete phantom disks from ODM)
- lqueryvg (lists various VG information)
- realpath (translate path to absolute form)
- dmpdt_chrp (dump OpenFirmware device tree)
- /usr/lib/nls/lstz (list timezone information)
If you want this list to be expanded, send me (or any other moderator) a message or post here. If you want to write documentation for a command: just do so. We will link your thread gladly to the command here so that your work is easily found.

Hi everybody!
In general the documentation of AIX is well done and rather complete. Still, there are a few undocumented parts of AIX and some of the undocumented commands offer things you just can't get done the "official" way. We once talked about collecting the information we collectively have... (0 Replies)

REALPATH(3) 1 REALPATH(3)
realpath - Returns canonicalized absolute pathname
SYNOPSIS
string realpath (string $path)
DESCRIPTION
realpath(3) expands all symbolic links and resolves references to '/./', '/../' and extra '/' characters in the input $path and returns the
canonicalized absolute pathname.
PARAMETERS
o $path
- The path being checked.
Note
Whilst a path must be supplied, the value can be blank or NULL In these cases, the value is interpreted as the current
directory.
RETURN VALUES
Returns the canonicalized absolute pathname on success. The resulting path will have no symbolic link, '/./' or '/../' components.
realpath(3) returns FALSE on failure, e.g. if the file does not exist.
Note
The running script must have executable permissions on all directories in the hierarchy, otherwise realpath(3) will return FALSE.
Note
Because PHP's integer type is signed and many platforms use 32bit integers, some filesystem functions may return unexpected results
for files which are larger than 2GB.
