       getaccess - list access rights to file(s)

       user] user] group[,group]...] file ...

       file ...

       lists for the specified files the effective access rights of the caller
       (that is, for their effective user ID, effective group ID, and  supple‐
       mentary groups list).  By default, the command prints a symbolic repre‐
       sentation of the user's access rights to the named file: or for read/no
       read,  or for write/no write, and or for execute/no execute (for direc‐
       tories, search/no search), followed by the file name.

       recognizes the following options and command-line arguments:

	      List access for the given user instead of the caller.
			     A user can be a known user name, a valid ID  num‐
			     ber,  or @, representing the file's owner ID.  If
			     information  about	 more	than   one   file   is
			     requested, the value of @ can differ for each.

			     This  option  sets	 the user ID only.  The access
			     check is made with the caller's  effective	 group
			     ID	 and  supplementary  group  IDs unless is also

	      List access for the  given  group(s)  instead  of	 the  caller's
	      effective group
			     ID and supplementary groups list.	A group can be
			     a known group name, a valid ID number, or @, rep‐
			     resenting	the  file's  group ID.	If information
			     about more than one file is requested, the	 value
			     of @ can differ for each.

	      List access using the caller's real user
			     ID,  group	 ID,  and  supplementary  groups list,
			     instead of effective ID values.

	      List access rights numerically
			     (octal digits instead of for each file requested.
			     The bit values and are defined in the file

       Checking	 access	 using access control lists is described in acl(5) and

       In addition, the write bit is cleared for files on read-only file  sys‐
       tems  or	 shared-text  programs being executed.	The execute bit is not
       turned off for shared-text programs open for writing because it is  not
       possible	 to ascertain whether a file open for writing is a shared-text

       Processes with appropriate privileges have read and write access to all
       files.	However,  write	 access	 is denied for files on read-only file
       systems or shared-text programs	being  executed.   Execute  access  is
       allowed	if  and	 only if the file is not a regular file or the execute
       bit is set in any of the file's ACL entries.

       To use successfully, the caller must have search access in every direc‐
       tory  component	of  the path name of the file.	verifies search access
       first by using the caller's effective IDs, regardless of the  user  and
       group IDs specified.  This is distinct from the case in which the call‐
       er can search the path but the user for whom access  is	being  checked
       does not have access to the file.

       Note:  a file name argument of has no special meaning (such as standard
       input) to

   Environment Variables
       determines the language in which messages are displayed.

       If is not specified or is set to the empty string,  a  default  of  "C"
       (see  lang(5))  is used instead of If any internationalization variable
       contains an invalid setting, behaves  as	 if  all  internationalization
       variables are set to "C".  See environ(5).

       returns one of the following values:

	      0	   Successful completion.

	      1	   was	invoked	 incorrectly or encountered an unknown user or
		   group name.	An appropriate message is printed to  standard

	      2	   A  file  is	nonexistent  or	 unreachable  (by the caller).
		   prints an appropriate message to standard error, continues,
		   then returns a value of 2 upon completion.

       The  following command prints the caller's access rights to file1 using
       the file's group ID instead of the  caller's  effective	group  ID  and
       groups list.

       Here's  how  to	check access by user in groups and to all files in the
       current directory, with access rights expressed as octal values.
