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.
