I'm using nssm.exe in my scripts to manage the windows services. But in PowerShell, the command output is coming with spaces after every alphabet.
PS> $nssm = (Get-Command D:\nssm.exe)
PS> & $nssm
nssm.exe : N S S M : T h e n o n - s u c k i n g s e r v i c e m a n a g e r

T o s h o w s e r v i c e e d i t i n g G U I :

How to get the output without such wide-format spaces among alphabets?

I am learning the basic part right now. And I found that the mult function contains plus as below:
Fixpoint mult (n m : nat) : nat :=
match n with
| O ⇒ O
| S n' ⇒ plus m (mult n' m)
end.
Example test_mult1: (mult 3 3) = 9.
Proof. simpl. reflexivity. Qed.
i unfold the mult and it showed
1 subgoal
______________________________________(1/1)
3 + (3 + (3 + 0)) = 9
I know that BC plus m and m is 3 so there are 3 times of plus. But I am curious where the 0 comes from. if this 3 means m, then where is n?
Thank you!
First, you should remember that 3 is a notation for S (S (S O))
When you ask for the computation of mult 3 3, only one step of mult, you get this:
mult 3 3 = mult (S 2) 3 = 3 + mult 2 3
Now if you compute mult 2 3 you get :
mult 2 3 = mult (S 1) 3 = 3 + mult 1 3
and then:
mult 1 3 = mult (S O) 3 = 3 + mult 0 3
and tnen:
mult 0 3 = 0
So the 0 that appears when computing mult comes from mult 0 3
I simplified the original problem up to this point
((P∧¬R)∨(¬Q∨R))∧((Q∧¬R)∨(¬P∨R))
, and I got stuck here. What would be the next step? Thanks for the help!!
I am solving it with you.
Hint-1: ((P∧Q)∨R) = (PVR) ∧ (QVR)
Hint-2: P ∧ True = P
Hint-3: P V True = True
Answer
It would be true in the end. Check it once.
Next step would be
= [(P V (~Q V R)) ^ ( ~R V (~Q V R))]
^[(Q V (~P V R)) ^ ( ~R V (~P V R))]
= (P V ~Q V R) ^ ( ~p V Q V R)
= R V ( (P V ~Q) ^ ( Q V ~P))
= R v (( Q -> P ) ^ ( P -> Q))
= R V (P <-> Q)
whenever R is True it is True.
Else
P Q P<->Q
------------------
F F T
F T F
T F F
T T T
So it conforms to the truth table. Shown above by trincot.
The following expressions are equivalent:
(p ⇒ r) ⇔ (q ⇒ r)
(¬p v r) ⇔ (¬q v r)
(¬p ⇔ ¬q) v r
(p ⇔ q) v r
(p ∧ q) v (¬p ∧ ¬q) v r
Truth table:
p q r result
---------------
0 0 0 1
0 0 1 1
0 1 0 0
0 1 1 1
1 0 0 0
1 0 1 1
1 1 0 1
1 1 1 1

My requirement is to find the location of a particular string in a line from notepad file but while reading it in powershell additional space get added that's why not able to find the location of a particular string. How I can find the location is this case??
I am using this code for achieving this
$ParamsPathForData = ($dir + "\TimeStats\TimeStats_1slot\29_12_2015_07TimeStats1.txt")
$data = Get-Content $ParamsPathForData
write-host $data.count total lines read from file
foreach ($line in $data)
{
$l =$line.IndexOf("12/29/2015")
write-host $l
}
I am reading this line from notepad ->
TimeStats 29 12/29/2015 7:13:42 AM +00:00 Debug PREPROCESS: SlotNo:

Change the the encoding to Unicode...
$data = Get-Content $ParamsPathForData -Encoding Unicode
I have a big data frame that looks like this:
name1 A A G
name2 C C T
name3 A G G
name4 H G G
name5 C - T
name6 C C C
name7 A G G
name8 G G A
I expect the data frame changed to:
name1 A A A A G G
name2 C C C C T T
name3 A A G G G G
name4 H H G G G G
name5 C C - - T T
name6 C C C C C C
name7 A A G G G G
name8 G G G G A A
