scp command does not work

The scp command will not work properly if your startup file in home directory like ~/.cshrc printing something on terminal with 'echo' command.

For example if the startup file on remote server [server0] as following:
# cat ~/.cshrc
USER_ENV=~/.cshrc.user
if [ -e $USER_ENV ]; then
  source $USER_ENV
  echo "Source file $USER_ENV successuflly"
fi

Then following command will fail:
scp test_file user1@server0:~
