Linux uses common error highlights

1. SCP Copy file failure issue

When any content output is generated during shell startup script (such as profile, BASHRC), scp/sftp will return these echoes As the protocol package for parsing, the result is naturally unable to read these content, resulting in the file copy failure.

If you can clearly know which statements in your /ETC/BASHRC and other files will produce the Echo content, you can do echo by conditional judgment:

If [$ (Expr index "$-" i)-ne 0]; Then
echo "Welcome to Shell, now:"
Date + '%y-%m-%d%T '
Fi

This will only be the real interactive login when the echo message, SCP automatically ignored.
