After the upgrade of MacOS, zsh has become the default shell, which conforms to the trend and begins the journey of using zsh.

The following error occurred when copying multiple files remotely using scp today:

# copy all configuration files in a directory (* .conf) scp host:/xxxx/*.conf. # error is as follows # zsh: no matches found: host:/xxxx/*.conf

It is certain that this command statement will work as scheduled in bash, and such a problem should be the fault of zsh. As a veteran linux user, you can quickly see the problem: zsh tried to expand the * wildcard, but the corresponding file was not found locally, resulting in a "no matches" error.

After a personal attempt and online search, there are two solutions:

Do not let zsh expand the *; the specific methods are:

Enclose the * part in quotation marks, single and double quotation marks are meaningless. For example: scp "host:/xxxx/*.conf". Or scp 'host:/xxxx/*.conf'. You can also refer only to the part of the path, for example: scp host:'/xxxx/*.conf'.

Use a backslash to prevent zsh from escaping: scp host:/xxxx/\ * .conf.

Set the nonomatch option so that when a zsh match fails, it does not report an error and uses the original content. To do this: setopt nonomatch, then use the scp command. The recommended practice is to write it to a .zshrc file and let it take effect automatically in future use.
