aegis -Develop_Begin_Undo -Help
The
aegis
-Develop_Begin_Undo
command is used to
reverse the effects of the 'aegis -Develop_Begin' command.
The development directory is discarded,
even if the change has files associated with it,
and even if the development directory is not empty;
all files in the development directory will be lost.
The change is returned to the
awaiting development
state.

The develop_begin_undo_command field of the project config
file is run, if set. See aepconf(5) for more information.
The following options are understood:
-Change numberThis option may be used to specify a particular change within a project. See aegis(1) for a complete description of this option.
-HelpThis option may be used to obtain more information about how to use the aegis program.
-InteractiveSpecify 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.
-KeepThis 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_KeepThis 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.
-ListThis option may be used to obtain a list of suitable subjects for this command. The list may be more general than expected.
-Project nameThis 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.
-REAson textThis option may be used to attach a comment to the change history generated by this command. You will need to use quotes to insulate the spaces from the shell.
-TERseThis option may be used to cause listings to produce the bare minimum of information. It is usually useful for shell scripts.
-User nameThis option may be used by project administrators to undo the effects of using the same option with the aedb(1) command.
-VerboseThis 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.
-WaitThis 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_WaitThis 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.
The recommended alias for this command is
csh% alias aedbu 'aegis -dbu \!* -v'
sh$ aedbu(){aegis -dbu "$@" -v}
It is an error if the change is no assigned to the current user. It is an error if the change is not in the being developed state.
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.
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.
