init_user_dotfiles.py¶
init_user_dotfiles.py - initialize user dot files (.cshrc, .bashrc, …)
Either initialize or just evaluate dot files for:¶
- having ABIN in PATH
- (for macs) having flat_namespace in DYLD_LIBRARY_PATH
- (optionally) sourcing apsearch tab completion setup file
.afni/help/all_progs.COMP (depending on shell)
- also, detect follower files
For example if .tcshrc sources .cshrc, then .tcshrc is a follower
and does not need be edited (though .cshrc might need editing).
For some background, please see:
afni_system_check.py -help_dot_files
This program can evaluate what might need to be done to the given files.
It can also make the needed changes.
The potential changes to evaluate or perform are:
1. Add ABIN to the PATH in all evaluated dot/RC files.
ABIN can be set by -dir_bin, or else it will be come from:
which afni_proc.py
2. If requested and on a mac, set DYLD_LIBRARY_PATH to include
/opt/X11/lib/flat_namespace.
3. If requested, source all_progs.COMP for tab completion of
AFNI command options. For example, try typing:
afni_proc.py -regr<tab>
Where <tab> is pressed when the cursor is still attached to 'regr'.
If tab completion is working, this should show many possible options
that start with -regr (-regress, actually). For a shorter example,
try:
afni -h<tab>
examples:¶
0. basic terminal examples: get help or list dot files¶
init_user_dotfiles.py -help
init_user_dotfiles.py -help_dotfiles_all
1. test dot files in the $HOME directory or in some/other/dir¶
# dot files under $HOME dir
init_user_dotfiles.py -test
# the dot files are under some/other/dir
init_user_dotfiles.py -test -dir_dot some/other/dir
# specify which shells to test (implying corresponding dot files)
init_user_dotfiles.py -test -shell_list tcsh bash
2. do a dry run, for just the path or ALL updates¶
# just PATH
init_user_dotfiles.py -do_updates path -dir_dot DDIR -dry_run
# all updates
init_user_dotfiles.py -do_updates ALL -dir_dot DDIR -dry_run
3. actually modify the files (e.g., just omit -dry_run)¶
# update for PATH
init_user_dotfiles.py -do_updates path -dir_dot DDIR
# perform all updates
init_user_dotfiles.py -do_updates ALL -dir_dot DDIR
# only consider .bashrc and .cshrc
init_user_dotfiles.py -do_updates ALL -dir_dot DDIR \
-dflist .bashrc .cshrc
# only consider shells bash and tcsh
init_user_dotfiles.py -do_updates ALL -dir_dot DDIR \
-shell_list bash tcsh
terminal options:¶
-help : show this help
-help_dotfiles_all : display dot files known by program
-help_dotfiles_mod : display modifiable dot files
-help_shells : display shells known by program
-hist : show module history
-show_valid_opts : list valid options
-ver : show current version
other options:
-dflist DFILE DFILE ... : specify dot files to focus on
(default from -help_dotfiles_mod)
e.g. -dflist .cshrc .bashrc .zshrc
Specify the list of RC/dot files to process. Files outside this
list will be ignored.
Special cases:
ALL : set list to all known dot files (see -help_dotfiles_all)
MOD : set list to all modifiable dot files (see -help_dotfiles_mod)
-dir_bin DIR_BIN : specify bin directory to add to PATH
(default comes from `which afni_proc.py`)
e.g. -dir_bin /some/other/abin
For use with 'path' modifications, specify the bin directory that
would be added to the PATH.
-dir_dot DDIR : specify directory containing dot files
e.g., -dir_dot some/dot/files/are/here
default: -dir_dot $HOME
Specify an alternate location of dot files, besides $HOME.
This can be for useful if being set up by an admin, or perhaps
for testing.
-do_updates UPD UPD ... : specify which updates to make
(default is nothing)
e.g. -do_updates flatdir
e.g. -do_updates path apsearch
e.g. -do_updates ALL
Specify one or more updates to attempt. Valid updates include:
apsearch : source ~/.afni/help/all_progs.COMP
(or all_progs.COMP.bash or all_progs.COMP.zsh)
* if the dotfile is not based on the login or current
shell (and no -force), omit apsearch update
(since this only applies to an interactive shell)
flatdir : add /opt/X11/lib/flat_namespace to DYLD_LIBRARY_PATH
path : add DIR_BIN to PATH
ALL : do all of the above
-dry_run : do not modify files, but see what would happen
e.g. -dry_run
With this option, the program prepares to modify files, but does not
actually perform the modifications. Instead, the user is informed of
what would be done, had the option not been included.
This is intended as a test run for a command that would otherwise
perform the operations specified by the -do_updates parameters.
This is similar to -test, except that it restricts operations to those
in -do_updates, plus it shows the actual text of all intended file
modifications. If a user wanted to make their own changes, for
example, they could append this modification text to each file in
question.
See also -test.
-force : force edits, whether they seem needed or not
e.g. -force
When considering changes to make (operations to add to the dot files),
if it seems to the program that the operation is already happening,
or if it does not seem appropriate (e.g. setting DYLD_LIBRARY_PATH on
a linux system), such a modification will be skipped.
Use this -force option to force a change, even if it looks like such a
change is not needed.
-make_backup yes/no : specify whether to make backups of originals
e.g., -make_backup no
default: -make_backup yes
By default, this program will make a backup of any file that will be
changed. The backup name will be the same as a original name, plus
the extension '.adot.bak'. For example:
.cshrc
would be backed up to
.cshrc.adot.bak
Use this option to turn off the default behavior.
-shell_list S1 S2 ... : specify shells instead of using -dflist
e.g., -shell_list bash tcsh
default: -shell_list ALL
This is an optional alternative to -dflist. The user can specify
a list of known shells which would imply the dot file list given by
-dflist. The same special cases of ALL and MOD apply.
For example,
-shell_list bash tcsh
would have the same effect as:
-dflist .bashrc .cshrc .tcshrc
This is merely a convenience option.
See also -dflist.
-test : just test the files for potential changes
e.g., -test
Use this option to simply report on what changes might be needed for
the given files. It checks for all possibly appropriate changes,
reporting the resulting table, and quits.
Use -do_updates to restrict the applied tests.
See also -dry_run, -do_updates.
-verb LEVEL : set the verbosity level (default 1)
e.g., -verb 2
Specify how verbose the program should be, from 0=quiet to 4=max.
As is typical, the default level is 1.
