6 years late to this answer, but VBScript can execute a command and store the output without relying on pipes or writing the output to temporary files.
This function executes a command (without displaying a console window) and returns the output as an array:
Function Execute_Command(sCmd)
Dim i : i = 0
Dim oExec : Set oExec = CreateObject("...

You should be able to right-click "Private Queues" and then click Refresh.
If this option has disappeared, you could use an alternate viewer:
Mqueue viewver
MSMQ QXplorer
(old software but may still work)

Just to provide a solution to creating a different log file each day...you can just call robocopy in Powershell or batch command file and do your file manipulation and have it create the log, then rename the log file on the next line. The example below is PowerShell.

Perhaps your file is being run, and the problem is that it doesn't output a valid HTTP response? I'd fix that first, though I'm not sure if the file is being run or not.
This is close to the minimal response:
#!/usr/bin/env perl
print "HTTP/1.1 200 OK\r\n";
print "Content-Type: text/plain\r\n";
print "\r\n";
print "test\r\...

rclone is an excellent solution that supports most remote filesystems including commercial options like box.
Example rclone ls:

If you run rclone on a remote headless computer there is an easy to use authentication mechanism in which you do a browser authentication on your local computer and copy a token to the remote ...

For anyone who wandered across this issue and didn't find the read-only flag to be the problem, I've stumbled across another fix for this.
For my situation it seems that on WSL2 when veracrypt is mounted, WSL doesn't actually mount the filesystem. I realized this when I didn't see an entry in the mount command. You can mount it via:
sudo mkdir -p /mnt/a

cd C:\abc

I confirm DavidPostill's answer is effective.
Another solution is to escape the "greater" sign in the SET command, using the "caret" symbol:
set delay3=ping localhost -n 3 ^>nul
It works the same way for "pipe" sign.
Escaping specials characters can be handy in complex command lines, with combination of FOR, IF, FINDSTR ... ...

A pipeline takes the output of one command
and uses it as the input to another command.
So there are two problems with what you tried.
The cd command doesn’t produce any output1.
file * doesn’t take any input.
You might say, “Of course it takes input; it reads (part of) all the files.”
But it doesn’t read standard input.
If you type file *, it just runs ...

I was able to get the result that (I guess) you want, sticking to CMD,
but breaking your monster command into multiple steps,
with an intermediate file:
copy/y nul %temp%\out1.txt
FOR /F "tokens=1 delims= " %P IN ('FINDSTR /M /I /R /C:"STATE.*=.*3" * ') DO (FINDSTR /I /S /C:"TCPHOST" %P) >> %temp%\out1.txt

Not exactly a solution, but if you have CygWin installed, you just do (example for a 500000000 bytes file) :
dd if=/dev/zero of=MyFile.zero bs=1 count=500000000
This is the same method you would use at any Unix-like operating system.

You can use the which command, and set the PATH variable just for the scope of that command. For example
PATH="/path1:/path2" which "file1.txt"
will return /path1/file1.txt if it exists, otherwise /path2/file1.txt if it exists.

cat file.sh | mongo … is UUOC, <file.sh mongo … is better.
Side note: why .sh? It doesn't matter to mongo or whatever, but people will expect file.sh to be a shell script. From now on I'm using file1 instead.
man 1 mongo gives an example: mongo script1.js script2.js script3.js, so I expect mongo … file1 to work as well.

The answer was to go in Windows 10 > Recover > Open System Restore and follow the steps to rollback to the restore point. I was fortunate that there was a point backed-up as I thought I had disabled this behaviour.

Passing variables to docker run from within a bash shell, getting “unterminated quoted string” error
General information
The quoting in your code is very wrong. Important information:
An unquoted variable undergoes word splitting and filename generation.
Quotes that appear from variable expansion are not special to the shell that expanded the variable.
There are two shells: the shell that interprets the script and the shell running in a container. Each ...

A solution I hadn't initially considered before I posted this question is to check the file exists before calling start, as follows:
if exist example.exe (
start example.exe
) else (
echo Error: 'example.exe' does not exist 1>&2
)
Strictly speaking, not a direct answer to my question as I originally stated it, but nonetheless serves my ...

Yes it could be evidence of a virus or malware
Yes you may be able to get back the command prompt by doing the following:
Run powershell as admin
Run the command sfc /scannow
It will repair missing or corrupted system files.

A quick idea is to use Get-ChildItem with the -Directory and -Recurse
options and use Start-Process and its -ArgumentList option to execute the python script passing it the full directory path.

$src = "C:\Folder\Path";
(Get-ChildItem $src -Directory -Recurse).FullName | % { Process {

Objects under ~\AppData\Local\Microsoft\WindowsApps are not files – they are execution aliases, implemented through reparse points. They're a bit like symlinks or junctions, in that they they only point to another file within a specific application package, although they include some additional metadata about the package and they only support being executed ...

Powershell doesn't evaluate variables in strings enclosed by single quotes. Use double quotes instead, or if the variable contains the entire string you want to use, and only that, don't bother to quote it at all:
$string_containing_filename_with_complete_path -replace $PSScriptRoot,""

This answer is slightly misleading. check Kamil Maciorowski's comment.
The easiest way to find out will be to use echo command. You can check what commands/programs receive after shell expansion.
$ echo {}
outputs: {}
$ echo '{}'
outputs: {}
$ echo \{\}
outputs {}
so there is no real difference between them. one can use either way.

In an answer to a similar question unreliable results with -ss in earlier versions are mentioned. But in new builds it appears the same. To recap, if you use ss/to/t
before -i, it cuts at i-frames,
after -i, it cuts at specified times and uses the next i-frame till this frame is reached, i.e. you get a still picture to that time. At the time for -to it may ...

A colleague and I found a powershell solution that requires no admin rights, and does not show any prompts. You can use the name of the font-file to install and uninstall. This makes it especially useful for scripting.

It's hard to be specific without knowing what you are trying to do. Here is a code block that might get you started.
get-childitem $HOME -recurse -filter "*.ps1" |
group-object length |
sort-object count -desc
This illustrates using the -recurse and -filter parameters to get a lot of files with the same extension, in this case .ps1. It then ...

You can use this command:
for /l %g in () do @( <your-command> & timeout /t 1 > nul )
This prevent the timeout command to write "Waiting for n seconds ..." so it's kind of silent.

You can also use sudo env PATH=$PATH ...rest_of_command_here.... Since that's not so convenient to type, I've added an alias alias sudop='sudo env PATH=$PATH'. The sudop (rather than aliasing sudo itself) is a reminder to me to make me aware that I am preserving my current environment path.

While your example is pretty easy to convert to BAT, you will fail on Windows' bigges weakness: lack of tools. There's no tr, sed, grep, etc.
Otherwise it's pretty straingforward. Echo doesn't need a replacement, cat is type, % is $ and so on, but as I said, yours won't work due to the lack of tools in Windows.

.?* is not "a wildcard" in PowerShell.
The -Replace operator in PowerShell doesn't use wildcard matching, it uses regular expressions.
In regular expressions, . will match any single character except a line break. ? and *, as well as + are quantifiers used in conjuction with . or other, more specific, matching characters. So that:
'.?' matches ...

I kept fiddling and worked it out:
