How to solve error of missing destination file operand after '/sdcard/ngrok/ngrok ' in termux

Question

I am using termux in my android but I get the following error when I want to copy some data from sdcard to $HOME IN TERMUX the following error shows up:
missing destination file operand after '/sdcard/ngrok/ngrok'
here are commands:

   $ cp /sdcard/ngrok/ngrok
   cp: missing destination file operand after '/sdcard/ngrok/ngrok'   
   try 'cp --help' for more information.

Solution

You said that you want to copy file from sdcard to $HOME, but your cp command doesn't have destination. Format of copy command is cp source destination. So right command is

cp sdcard/ngrok/ngrok $HOME

Make sure that sdcard/ngrok/ngrok is a file. If it is a directory then use -r option i.e.

cp -r sdcard/ngrok/ngrok $HOME

Also try cp --help for more information about cp command.

@Ronny What is the error?

@Ronny may be it is not file, if it directory then use -r option. See update.
