I also liked Qwertiy's answer best. Here is a script (works for an arbitrary number of files, also for .mov; tested on macOS):

exit 0

Yes, it is legal.
FFmpeg is released under GNU Lesser General Public License (LGPL) version 2.1 or later. Some external libraries like libx264 get released in GPL 2 or later. But both of them have permissions for free/commercial usage, distribution, or modification. So you can use FFmpeg in your both commercial or free software. And you can release the ...

For fish shell:
Since no one has made a solution for the fish shell, I'd like to give it a try.
Just making a Fish version out of the answers given here, so consider this, Fish Shell edition. 😎
1st solution is based from @Grigory K answer.

Actually the answer is No.
ping is a troubleshooting command line tool which's task is to send ICMP packets to other host. When we ping any IP address it generates ICMP Echo Requests, if the packet can reach the destination successfully the destination device will respond with ICMP Echo Response. The main purpose of this is to check if a server, website or ...

Microsoft has made it much more difficult to view protection history. To open Defender, use a shortcut to ms-settings:windowsdefender ... but then as you state you must manually open Virus & threat protection, which then runs SecHealthUI.exe in "C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy".

man pivot_root tells:
Note that exec chroot changes the running executable, which is necessary if the old root directory should be unmounted afterwards.
Same goes for a few other resources as mentioned afterward.
Without chroot to the newer filesystem the umount command will fail with EBUSY, because the shell's process is still keeping a resource usage in ...

All of the functions mentioned in http://zsh.sourceforge.net/Doc/Release/User-Contributions.html need to be autoloaded before you can use them. You don't need to add them to your $fpath, though; Zsh will be able to find them automatically.
So, to get access to zmv, you simply need to add the following to your ~/.zhsrc file:
autoload -Uz zmv

Here's how to do it properly in Zsh, with arrays:
common-files() {
file-names $1 && local -a files_a=( $reply )
file-names $2 && local -a files_b=( $reply )

# `(F)`: Join the items with newlines.
print ${(F)files_a:*files_b}
}
file-names() {
# `.`: Match only files (not dirs).

It seems that --strip-components and -C options need to precede the file to extract, otherwise they are silently ignored.
I suppose the man page hints at this
tar -x [-f ARCHIVE] [OPTIONS] [MEMBER...]
But in some contexts (https://askubuntu.com/a/45354/596667) it seems to be ok at the end.
The correct command line is thus

cd is a shell builtin command, so just use builtin cd "$@" to get the original behavior. There is also command ... but which applies only to external commands in zsh. Both are explained in man zshbuiltins or have a look into the PRECOMMAND MODIFIERS section in man zshmisc.

For me it was caused by the executable being set to run as administrator in the compatability settings.

You can search for a list of files in "Everything" by delimiting with |.

I like the following approach:
du -schx .[!.]* * | sort -h
where:
s: display only a total for each argument
c: produce a grand total
h: print sizes in a human-readable format
x: skip directories on different file systems
.[!.]* *: Summarize disk usage of each file, recursively for directories (including "hidden" ones)

adding a second % before N apparently fixed it.
set Logpath="C:\Users\bob\Desktop\project\a.txt"
set StringToLookFor="asdf"
set NUM=0
for /F %%N in ('find /C %StringToLookFor% ^< %Logpath%') do set NUM=%%N
pause
echo %NUM%

If you need it to pause for a specific amount of time, how about using timeout?

Windows 10 Command Prompt Can Be Closed using ALT+F4 Hotkey claims that this problem affects only Windows up to 8.1.
Windows 10 Command Prompt duly responds to ALT+F4
It also mentions that Alt + F4 can be disabled in Windows 10 to mimick the old behaviour by creating a registry key REG_DWORD AllowAltF4Close set to 0 in HKEY_CURRENT_USER\Console.

Based on
Is there a way to batch rename files to lowercase,
here is a formulation that does files and folders recursively:
for /f "Tokens=*" %f in ('dir /l/b/s') do (rename "%f" "%f")

Try this powershell code:
Get-childItem "Filepath" -Recurse | Rename-Item -NewName {$_.Basename.tostring().tolower() + $_.extension}
This will recursively rename all files and folders in "Filepath" to lower case.

You can use this:
cmd.exe /k "cd /d "Filepath" & start program.exe"
/k switch tells to keep command prompt open after command execution.
cd changes directory to the file path, /d switch makes it safer because without this switch over-drive paths cannot be changed.
Then start the program.

I think what you're asking for is something like this in a .bat batch file
Create a new file called shortcut.bat. In the file create the following:
cd c:\path to file\
Start program.exe

When you run shortcut.bat it'll fire up a command window, start your program and leave the command window open.

I highly suspect the "contents of the list.txt file" you posted is an interpretation (representation) of the actual content, not the literal content. Then it makes sense.
