error of "FIND: Parameter format not correct" in powershell i'm getting an error of &quot;FIND: Parameter format not correct&quot; in powershell The following works from CMD C:\Users\User&gt;echo abc | find &quot;a&quot; abc  C:\Users\User&gt;echo abc&gt;z.z  C:\Users\User&gt;find &quot;a&quot; z.z  ---------- Z.Z abc  C:\Users\User&gt;  But this fails from powershell! PS C:\Users\User&gt; echo abc | find &quot;a&quot; FIND: Parameter format not correct PS C:\Users\User&gt; echo abc &gt;z.z PS C:\Users\User&gt; find &quot;a&quot; z.z FIND: Parameter format not correct PS C:\Users\User&gt;  There is a similar question here   where the answer says to use quotation marks with the find command. Though I have   And I wouldn't be using /C because i'm not trying to count occurrences. Though find /c isn't working either PS C:\Users\User&gt; find /C &quot;a&quot; z.z FIND: Parameter format not correct PS C:\Users\User&gt;  And it's not a UK keyboard issue, where two pipe characters get swapped. 'cos it works in cmd and not powershell. And I tried copy/pasting the correct pipe character from charmap.  And as yo see this occurs also with the format of find [pattern] file. So without any pipe. So, not a pipe issue. There's something about powershell and find, that is going wrong here. Where cmd is fine. Added Upon further investigation PS C:\Users\User&gt; which find /cygdrive/c/Windows/system32/find PS C:\Users\User&gt;  Makes me wonder, is that a PATH problem it's clashing with cygwin? I don't think it's a PATH problem, because that's just cygwin's way of stating that the path is in c:\windows\system32  but does look like a weird clash with cygwin though in some way.. not sure if relevant to the problem. It is running windows FIND PS C:\Users\User&gt; find /? Searches for a text string in a file or files.  FIND [/V] [/C] [/N] [/I] [/OFF[LINE]] &quot;string&quot; [[drive:][path]filename[ ...]]    /V         Displays all lines NOT containing the specified string.   /C         Displays only the count of lines containing the string.   /N         Displays line numbers with the displayed lines.   /I         Ignores the case of characters when searching for the string.   /OFF[LINE] Do not skip files with offline attribute set.   &quot;string&quot;   Specifies the text string to find.   [drive:][path]filename              Specifies a file or files to search.  If a path is not specified, FIND searches the text typed at the prompt or piped from another command. PS C:\Users\User&gt;
Why can "find" not be used in PowerShell? What does find.exe find objectionable about the parameters when it is used in a PowerShell console shell?  These commands work as expected in a cmd.exe shell:  PS C:\Windows\System32\WindowsPowerShell\v1.0&gt; find /i "System.Diagnostics.Process" *.ps1xml FIND: Parameter format not correct PS C:\Windows\System32\WindowsPowerShell\v1.0&gt; find /i "System.Diagnostics.Process" *.ps1xml FIND: Parameter format not correct PS C:\Windows\System32\WindowsPowerShell\v1.0&gt; C:\Windows\System32\find.exe /i "System.Diagnostics.Process" *.ps1xml FIND: Parameter format not correct PS C:\Windows\System32\WindowsPowerShell\v1.0&gt; C:\Windows\System32\find.exe /i "System.Diagnostics.Process" .\DotNetTypes.format.ps1xml FIND: Parameter format not correct
I'm studying the Darboux definition of integrability, which I completely explained . There's an exercise that asks me to prove that the Darboux Integrability is equivalent to Riemann Integrability, but this Riemann integral is defined as the following:  It first defines a 'pointed' partition (I don't know how to say it in ensligh) by the following: a 'pointed' partition $[a,b]$ is a pair $P^*=(E,ξ)$, where $P=\{t_0, t_1, \cdots, t_n\}$ is a partition of $[a,b]$ and $ξ = (ξ_1, \cdots, ξ_n)$ is a list of $n$ chosen numbers such that $t_{i-1}\le ξ_i\le t_i$ for each $i=1,\cdots ,n$.  Now, the Riemann Integral is defined as:  $$\sum(f,P^*) = \sum_{i=1}^n f(ξ_i)(t_i-t_{i-1})$$  (I didn't understand the notation for the left hand side of the equation, by the way)  Finally, I'm asked to prove the following: given $f,g:[a,b]\to \mathbb{R}$ integrable functions, for the entire partition $P=\{t_0, \cdots, t_n\}$ of $[a,b]$ let $P^* = (P,ξ)$ and $P^{\#} = (P, η)$ be pointed partitions of $P$, then:  $$\lim_{|P|\to 0}\sum f(ξ_i)g(η_i)(t_i-t_{i-1}) = \int_a^b f(x)g(x) \ dx$$  I guess here I need to prove that the Riemann Integral of the product of two functions if the darboux integral of $f(x)g(x)$, but it seems too obvious, I just need to verify that $f,g$ are integrable, then their product is too, isn't it? I'm pretty sure this should be a hard question. Is there another interpretation that I'm missing? I played around with it for a while, but I simply can't figure it out.  I made a tank that fires missiles, and when the missiles hit the walls, I want them to bounce off, but I want them to bounce off to the right angle.  Right now I haven't got any obstacles, the missiles just bounce off when they get outside the viewportRectangle I made.  Is the solution I'm looking for quite advanced?  Is there a relativly simple way to do it? What is the difference between ANSI/ISO C++ and C++/CLI? Are token creatures considerd as a creature spell? Are token creatures considerd creature spells?

But I just saw the following while searching MSE:        Direct link to the question on ruSO:   Perhaps the HNQ filter works on question title (in the current case there are no non-Latin symbols) instead of site origin. Hence, according to the post mentioned before this behaviour should be interpreted as a bug.   However, I suggest to fix such "bug" by taking another feature request in mind: Overriding the java equals() method - not working?

What are the meanings of &lt; and ! in columns specification? 14 months ago, an  supplement was published that discussed how the ranger described in the Player's Handbook was under powered. These rules reimagined the ranger's abilities, and suggested that an official version would be released later.     Finally, we come to implementation. If this iteration of the ranger, or a future revision of it, grades high enough, our plan is to present it as a revised ranger in a future D&amp;D sourcebook.   Does that Sourcebook exist yet? If not, have the devs given an update or told us their intentions? Are there any non-decreasing securities on the stock market?
