runat(1)                         User Commands                        runat(1)

NAME
       runat - execute command in extended attribute name space

SYNOPSIS
       /usr/bin/runat file [command]

DESCRIPTION
       The  runat utility is used to execute shell commands in a file's hidden
       attribute directory. Effectively,  this  utility  changes  the  current
       working  directory to be the hidden attribute directory associated with
       the file argument and then executes the  specified  command  in  a  new
       shell process. If no command argument is provided, an interactive shell
       is  spawned.  The  environment  variable $SHELL defines the shell to be
       spawned. If this variable is undefined, the default shell, /bin/sh,  is
       used.


       The file argument can be any file, including a directory, that can sup‐
       port  extended  attributes. It is not necessary that this file have any
       attributes, or be prepared in any way, before invoking the  runat  com‐
       mand.

OPERANDS
       The following operands are supported:

       file       Any  file,  including a directory, that can support extended
                  attributes.


       command    The command to be executed in an attribute directory.


ERRORS
       A non-zero exit status will be returned if runat cannot access the file
       argument, or the file argument does not support extended attributes.

USAGE
       See fsattr(7) for a detailed description of extended file attributes.


       The process context created by the runat command has its current  work‐
       ing  directory  set  to  the hidden directory containing the file's ex‐
       tended attributes. The parent of this directory (the ".." entry) always
       refers to the file provided on the command line. As such, it may not be
       a directory. Therefore, commands (such as pwd)  that  depend  upon  the
       parent  entry being well-formed (that is, referring to a directory) may
       fail.


       In the absence of the command argument, runat will spawn a new interac‐
       tive shell with its current working directory set to  be  the  provided
       file's hidden attribute directory. Notice that some shells (such as zsh
       and  tcsh)  are not well behaved when the directory parent is not a di‐
       rectory, as described above. These  shells  should  not  be  used  with
       runat.

EXAMPLES
       Example 1 Using runat to list extended attributes on a file


         example% runat file.1 ls -l
         example% runat file.1 ls


       Example 2 Creating extended attributes


         example% runat file.2 cp /tmp/attrdata attr.1
         example% runat file.2 cat /tmp/attrdata > attr.1


       Example 3 Copying an attribute from one file to another


         example% runat file.2 cat attr.1 | runat file.1 "cat > attr.1"


       Example 4 Using runat to spawn an interactive shell


         example% runat file.3 /bin/sh




       This  spawns  a new shell in the attribute directory for file.3. Notice
       that the shell will not be able to determine what your  current  direc‐
       tory  is.  To  leave  the  attribute directory, either exit the spawned
       shell or change directory (cd) using an absolute path.



       Recommended methods for performing basic attribute operations:


       display               runat file ls [options]


       read                  runat file cat attribute


       create/modify         runat file cp absolute-file-path attribute


       delete                runat file rm attribute


       permission changes
                               runat file chmod mode attribute
                               runat file chgrp group attribute
                               runat file chown owner attribute



       interactive shell
                             runat file /bin/sh
                              or set your $SHELL to /bin/sh and
                             runat file



       The above list includes commands that are known  to  work  with  runat.
       While  many other commands may work, there is no guarantee that any be‐
       yond this list will work. Any command that relies on being able to  de‐
       termine  its  current  working directory is likely to fail. Examples of
       such commands follow:

       Example 5 Using man in an attribute directory


         example% runat file.1 man runat
         >getcwd: Not a directory


       Example 6 Spawning a tcsh shell in an attribute directory


         example% runat file.3 /usr/bin/tcsh
         tcsh: Not a directory
         tcsh: Trying to start from "/home/user"




       A new tcsh shell has been spawned with the  current  working  directory
       set to the user's home directory.

       Example 7 Spawning a zsh shell in an attribute directory


         example% runat file.3 /usr/bin/zsh
         example%




       While the command appears to have worked, zsh has actually just changed
       the  current  working  directory  to  '/'.  This  can  be seen by using
       /bin/pwd:


         example% /bin/pwd
         /


ENVIRONMENT VARIABLES
       SHELL    Specifies the command shell to be invoked by runat.


EXIT STATUS
       The following exit values are returned:

       125    The attribute directory of the file referenced by the file argu‐
              ment cannot be accessed.


       126    The exec of the provided command argument failed.



       Otherwise, the exit status returned is the exit status of the shell in‐
       voked to execute the provided command.

ATTRIBUTES
       See attributes(7) for descriptions of the following attributes:

       tab() box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) ATTRIBUTE  TYPEAT‐
       TRIBUTE  VALUE  _  Availabilitysystem/core-os  _ CSIEnabled _ Interface
       StabilityCommitted

NOTES
       It is not always obvious why a command fails in runat when it is unable
       to determine the current working directory. The errors resulting can be
       confusing and ambiguous (see the tcsh and zsh examples above).
