scp error when using wildcard
Hello,

Every time my script runs I want it to go and copy all the files from a remote server directory to my local directory. Whenever I have files in the remote directory the command
Code:
scp -p $proxy_user@$proxy_server:"$remote_dir/*" ${local_dir}

executes with 0; when I have no files in the remote directory it throws an error saying No Such File or Directory and returns >0. How can I avoid the error message if there are no files to copy? I understand I could SSH and run a command to see if there are any files to copy, but is there a way around that?

Thanks

I am guessing here as I don't use scp and only use bash terminal but here goes:-
Code:
scp -p $proxy_user@$proxy_server:"$remote_dir"/* ${local_dir}

Note the quote has been shifted and /* left open...

If it does work I suspect it will transfer all subdirectories too except protected ones...

EDIT:
I have probably misread what you needed.
Just do a simple test:-
Code:
Last login: Mon Dec 30 23:56:50 on ttys000
AMIGA:barrywalker~> remote_dir="/Users/barrywalker/Empty"
AMIGA:barrywalker~> ls "$remote_dir"
AMIGA:barrywalker~> 
AMIGA:barrywalker~> ls "$remote_dir"/*
ls: /Users/barrywalker/Empty/*: No such file or directory
AMIGA:barrywalker~> ls "$remote_dir"'/*'
ls: /Users/barrywalker/Empty/*: No such file or directory
AMIGA:barrywalker~> ls "$remote_dir/*"
ls: /Users/barrywalker/Empty/*: No such file or directory
AMIGA:barrywalker~> _

The error will occur because the statment is true there is "No such file or directory"...

Code:
scp -p $proxy_user@$proxy_server:"$remote_dir"/* ${local_dir} 2>/dev/null

will keep it from sending the error to stdout but you now run the risk of not knowing whether there were no files or the command just failed unless you test the return code.
