NAME
aegis new file undo - remove new files from a change
SYNOPSIS
aegis -New_File_Undo file-name... [ option... ]
aegis -New_File_Undo -List [ option... ]
aegis -New_File_Undo -Help
DESCRIPTION
The aegis -New_File_Undo command is used to remove new files from a
change (reverse the actions of the ’aegis -New_File’ command). The
file is removed from the list of files in the change.
The file is removed from the development directory unless the -Keep
option is used. 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 specify a directory name to remove all new files in the named
directory tree, other files in the tree will be ignored. It is an
error if there are no relevant files.
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.
Notification
The new_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.
Process Side Effects
This command will cancel any build or test registrations, because
deleting a file logically invalidates them.
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.
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.
-TERse
This option may be used to cause listings to produce the bare
minimum of information. It is usually useful for shell
scripts.
-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.
-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.
-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 aenfu ’aegis -nfu \!$ -v’
sh$ aenfu(){aegis -nfu "$@" -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.
It is an error if the file is not in the change.
It is an error if the file was not added to the change with the ’aegis
-New_File’ command.
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.
