Windows Server 2003 and later (i.e. anything after Windows XP 32 bit) provide the where.exe
program which does some of what which
does, though it matches all types of files, not just executable commands. (It does not match built-in shell commands like cd
.) It will even accept wildcards, so where nt*
finds all files in your %PATH%
and current directory whose names start with nt
.
Try where /?
for help.
Note that Windows PowerShell defines where
as an alias for the Where-Object
cmdlet, so if you want where.exe
, you need to type the full name instead of omitting the .exe
extension.
You can specify formal arguments in rake by adding symbol arguments to the task call. For example:
require 'rake'
task :my_task, [:arg1, :arg2] do |t, args|
puts "Args were: #{args} of class #{args.class}"
puts "arg1 was: '#{args[:arg1]}' of class #{args[:arg1].class}"
puts "arg2 was: '#{args[:arg2]}' of class #{args[:arg2].class}"
end
task :invoke_my_task do
Rake.application.invoke_task("my_task[1, 2]")
end
# or if you prefer this syntax...
task :invoke_my_task_2 do
Rake::Task[:my_task].invoke(3, 4)
end
# a task with prerequisites passes its
# arguments to it prerequisites
task :with_prerequisite, [:arg1, :arg2] => :my_task #<- name of prerequisite task
# to specify default values,
# we take advantage of args being a Rake::TaskArguments object
task :with_defaults, :arg1, :arg2 do |t, args|
args.with_defaults(:arg1 => :default_1, :arg2 => :default_2)
puts "Args with defaults were: #{args}"
end
Then, from the command line:
> rake my_task[1,false]
Args were: {:arg1=>"1", :arg2=>"false"} of class Rake::TaskArguments
arg1 was: '1' of class String
arg2 was: 'false' of class String
> rake "my_task[1, 2]"
Args were: {:arg1=>"1", :arg2=>"2"}
> rake invoke_my_task
Args were: {:arg1=>"1", :arg2=>"2"}
> rake invoke_my_task_2
Args were: {:arg1=>3, :arg2=>4}
> rake with_prerequisite[5,6]
Args were: {:arg1=>"5", :arg2=>"6"}
> rake with_defaults
Args with defaults were: {:arg1=>:default_1, :arg2=>:default_2}
> rake with_defaults['x','y']
Args with defaults were: {:arg1=>"x", :arg2=>"y"}
As demonstrated in the second example, if you want to use spaces, the quotes around the target name are necessary to keep the shell from splitting up the arguments at the space.
Looking at the code in rake.rb, it appears that rake does not parse task strings to extract arguments for prerequisites, so you can't do task :t1 => "dep[1,2]"
. The only way to specify different arguments for a prerequisite would be to invoke it explicitly within the dependent task action, as in :invoke_my_task
and :invoke_my_task_2
.
Note that some shells (like zsh) require you to escape the brackets: rake my_task\['arg1'\]

If that question is connected to your other Hudson questions use the command they provide. This way with XML from the command line:
You need to change it a little bit to read from a file:
Read the manpage. following an abstract for -d Parameter.
