NAME

updatehome - update the home directory copy and link files for the current label

SYNOPSIS

/usr/bin/updatehome  [-cirs]

DESCRIPTION

updatehome reads the user's minimum-label copy and link-control files (.copy_files and .link_files). These files contain a list of files to be copied and symbolically linked from the user's minimum-label home directory to the user's home directory at the current label.

The Solaris Trusted Extensions dtsession program performs an updatehome whenever a newly labeled workspace is created so that the user's favorite files are available for use. For example, the user probably wants a symbolic link to such files as .profile, .login, .cshrc, .exrc, .mailrc, and ~/bin. The updatehome command provides a convenient mechanism for accomplishing this symlink. The user can add files to those to be copied (.copy_files) and to those to be symbolically linked (.link_files).

OPTIONS

-c

: Replace existing home-directory copies at the current label. The default is to skip over existing copies.

-i

: Ignore errors encountered. The default aborts on error.

-r

: Replace existing home-directory copies or symbolic links at the current label. This option implies options -c and -s. The default is to skip over existing copies or symbolic links.

-s

: Replace existing home-directory symbolic links at the current label. The default is to skip over existing symbolic links.

EXIT STATUS

Upon success, updatehome returns 0. Upon failure, updatehome returns 1 and writes diagnostic messages to standard error.

EXAMPLES

Example 1 A Sample .copy_files File

The files that are listed in .copy_files can be modified at every user's label.

.cshrc 
.mailrc 
.mozilla/bookmarks.html

Example 2 A Sample .link_files File

The files that are listed in .link_files can be modified at the lowest label. The changes propagate to the other labels that are available to the user.

~/bin
.mozilla/preferences
.xrc
.rhosts

Example 3 Updating the Linked and Copied Files

The .copy_files and .link_files were updated by the user at the minimum label. At a higher label, the user refreshes the copies and the links. No privileges are required to run the command.
