PROGRAM:

NAME

aegis copy file undo - reverse action of aecp

SYNOPSIS

aegis -CoPy_file_Undo [ option... ] filename...
aegis -CoPy_file_Undo -List [ option... ]
aegis -CoPy_file_Undo -Help

DESCRIPTION

The aegis -CoPy_file_Undo command is used to delete files previously copied into a
change. The named files will be removed from the list of files in the change.

The file is deleted from the development directory unless the -Keep option is specified.
The -Keep option should be used with great care, as you can confuse tools such as make(1)
by leaving these files in place.

You may name a directory to delete from the change all files in that directory tree
previously copied into the change, other files in the tree will be ignored. It is an
error if there are no relevant files.

Branch vs Change
The aecpu(1) command may only be applied to a change. If you wish to perform the same
operation on a branch, use the aemt(1) command, through the agency of a change.

File Name Interpretation
The aegis program will attempt to determine the project file names from the file names
given on the command line. All file names are stored within aegis projects as relative
to the root of the baseline directory tree. The development directory and the
integration directory are shadows of this baseline directory, and so these relative names
apply here, too. Files named on the command line are first converted to absolute paths
if necessary. They are then compared with the baseline path, the development directory
path, and the integration directory path, to determine a baseline-relative name. It is
an error if the file named is outside one of these directory trees.

The -BAse_RElative option may be used to cause relative filenames to be interpreted as
relative to the baseline path; absolute filenames will still be compared with the various
paths in order to determine a baseline-relative name.

The relative_filename_preference in the user configuration file may be used to modify
this default behavior. See aeuconf(5) for more information.

Process Side Effects
This command will cancel any build or test registrations, because deleting a file
logically invalidates them. If the project configuration file was deleted, any diff
registration will also be canceled.

The difference file (,D) will also be removed, however any DMT derived files (e.g a .o
file from a .c file) will not be removed. This is because aegis is decoupled from the
DMT, and cannot know what these derived file may be called. You may need to delete
derived files manually.

Notification
The copy_file_undo_command in the project config file is run, if set. The project_file_‐
command is also run, if set, and if there has been an integration recently. See
aepconf(5) for more information.

OPTIONS

The following options are understood:

-BAse_RElative
This option may be used to cause relative filenames to be considered relative to
the base of the source tree. See aeuconf(5) for the corresponding user
preference.

-CUrrent_RElative
This option may be used to cause relative filenames to be considered relative to
the current directory. This is usually the default. See aeuconf(5) for the
corresponding user preference.

-Change number
This option may be used to specify a particular change within a project. See
aegis(1) for a complete description of this option.

-Help
This option may be used to obtain more information about how to use the aegis
program.

-Interactive
Specify that aegis should ask the user for confirmation before deleting each
file. Answer the question yes to delete the file, or no to keep the file. You
can also answer all to delete the file and all that follow, or none to keep the
file and all that follow.

Defaults to the user's delete_file_preference if not specified, see aeuconf(5)
for more information.

If aegis is running in the background, the question will not be asked, and the
files will be deleted.

-Keep
This option may be used to retain files and/or directories usually deleted or
replaced by the command. Defaults to the user's delete_file_preference if not
specified, see aeuconf(5) for more information.

-No_Keep
This option may be used to ensure that the files and/or directories are deleted
or replaced by the command. Defaults to the user's delete_file_preference if not
specified, see aeuconf(5) for more information.

-List
This option may be used to obtain a list of suitable subjects for this command.
The list may be more general than expected.

-Project name
This option may be used to select the project of interest. When no -Project
option is specified, the AEGIS_PROJECT environment variable is consulted. If
that does not exist, the user's $HOME/.aegisrc file is examined for a default
project field (see aeuconf(5) for more information). If that does not exist,
when the user is only working on changes within a single project, the project
name defaults to that project. Otherwise, it is an error.

-Read_Only
This option may be used to specify that only insulation files are to be uncopied.
If you specify -UNChanged as well, only unchanged insulation files will be
uncopied.

-TERse
This option may be used to cause listings to produce the bare minimum of
information. It is usually useful for shell scripts.

-Verify_Symbolic_Links
This option may be used to request that the symbolic links, or hard links, or
file copies, in the work area be updated to reflect the current state of the
baseline. This is controlled by the development_directory_style field of the
project configuration file. Only files which are not involved in the change are
updated. See also the “symbolic_links_preference” field of aeuconf(5). This
option is the default, if meaningful for your configuration. The name is an
historical accident, hard links and file copies are included.

-Assume_Symbolic_Links
This option may be used to request that no update of baseline mirror files take
place. This options is useful when you definitely know the files' up-to-date-
ness isn't important right now; incorrect use of this option may have
unanticipated build side-effects. See also the “symbolic_links_preference” field
of aeuconf(5). This option is the default, if not meaningful for your
configuration. The name is an historical accident, hard links and file copies
are included.

-UNChanged
Examine the named files to see if they are unchanged. Only remove the unchanged
files from the change, and leave the files which have changed. If no files are
named on the command line all change files are checked.

-Verbose
This option may be used to cause aegis to produce more output. By default aegis
only produces output on errors. When used with the -List option this option
causes column headings to be added.

-Wait This option may be used to require Aegis commands to wait for access locks, if
they cannot be obtained immediately. Defaults to the user's lock_wait_preference
if not specified, see aeuconf(5) for more information.

-No_Wait
This option may be used to require Aegis commands to emit a fatal error if access
locks cannot be obtained immediately. Defaults to the user's
lock_wait_preference if not specified, see aeuconf(5) for more information.

See also aegis(1) for options common to all aegis commands.

All options may be abbreviated; the abbreviation is documented as the upper case letters,
all lower case letters and underscores (_) are optional. You must use consecutive
sequences of optional letters.

All options are case insensitive, you may type them in upper case or lower case or a
combination of both, case is not important.

For example: the arguments "-project, "-PROJ" and "-p" are all interpreted to mean the
-Project option. The argument "-prj" will not be understood, because consecutive
optional characters were not supplied.

Options and other command line arguments may be mixed arbitrarily on the command line,
after the function selectors.

The GNU long option names are understood. Since all option names for aegis are long,
this means ignoring the extra leading '-'. The "--option=value" convention is also
understood.

RECOMMENDED ALIAS

The recommended alias for this command is
csh% alias aecpu 'aegis -cpu \!* -v'
sh$ aecpu(){aegis -cpu "$@" -v}

ERRORS

It is an error if the change is not in the being developed state.
It is an error if the change is not assigned to the current user.

EXIT STATUS

The aegis command will exit with a status of 1 on any error. The aegis command will only
exit with a status of 0 if there are no errors.

ENVIRONMENT VARIABLES

See aegis(1) for a list of environment variables which may affect this command. See
aepconf(5) for the project configuration file's project_specific field for how to set
environment variables for all commands executed by Aegis.
