|

From time to time you will need to clean up your target tree. Since
|
||||
version 2, Stow provides a new utility @command{chkstow} to help with
|
||||
this. It includes three operational modes which performs checks that
|
||||
would generally be too expensive to be performed during normal stow
|
||||
execution.
|
||||
|
||||
I've added a -l option to chkstow
|

which will give you a listing of every package name that has already been stowed

should be able to diff this with your directory listing
|
||||
The syntax of the @code{chkstow} command is:
|
||||
|
||||
bash
|
||||
cd build/scripts
|
||||
diff <(../bin/chkstow -l) <(ls -1)
|
||||

chkstow [@var{options}]

The following options are supported:
|
||||
|
||||
@table @samp
|
||||
|
||||
@item -t @var{dir}
|
||||
@itemx --target=@var{dir}
|
||||
Set the target directory to @var{dir} instead of the parent of the stow
|
||||
directory. Defaults to the parent of the stow directory, so it is typical to
|
||||
execute @code{stow} from the directory @file{/usr/local/stow}.
|

@item -b

@itemx --badlinks
