aegis -CoPy_file_Undo(1)    General Commands Manual   aegis -CoPy_file_Undo(1)

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 direc-
	tory are shadows of this baseline directory, and so these relative
	names apply here, too.	Files named on the command line	are first con-
	verted 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 infor-
	mation.

   Process Side	Effects
	This command will cancel any build or test registrations, because
	deleting a file	logically invalidates them.  If	the project configura-
	tion 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 be-
	cause aegis is decoupled from the DMT, and cannot know what these de-
	rived file may be called.  You may need	to delete derived files	manu-
	ally.

   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 con-
		sidered	relative to the	base of	the source tree.  See aeu-
		conf(5)	for the	corresponding user preference.

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

	-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 speci-
		fied, 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	direc-
		tories are deleted or replaced by the command.	Defaults to
		the user's delete_file_preference if not specified, see	aeu-
		conf(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	envi-
		ronment	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 sin-
		gle project, the project name defaults to that project.	 Oth-
		erwise,	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 re-
		flect the current state	of the baseline.  This is controlled
		by the development_directory_style field of the	project	con-
		figuration 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 meaning-
		ful for	your configuration.  The name is an historical acci-
		dent, 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 def-
		initely	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	com-
		mand 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.  De-
		faults 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 op-
	tional.	 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	inter-
	preted 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	"--op-
	tion=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	er-
	rors.

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.
