Re: shell expansion (globbing) from inside php cli script

I tried that too. I get '/{a,s,d,f\}' in the string if I use it that way. Are you saying that you were able to do a succesful transfer using the above? I can output a string that SHOULD work, e.g. "scp joe@foobar.com:/dir/{file1,file2,file3} /dir/." but when run from within a php script it does not expand the stuff inside the braces. Instead it's looking for a file literally named '{file1,file2,file3}' rather than /dir/file1, /dir/file2, /dir/file3, etc. If you just echo the string it will appear well formed, but try to actually use it and it will not work, at least not for me. -Brian

Brian, The script works for me, I should have included the screen input/output, which now follows:

While running my tests I found that any whitespace within the brackets would cause a failure. If you run your script with "scp -v " you can see each file being copied (or not copied). Here's my output, NOTICE THAT THE $cmd STRING ECHOED BY THE COMMAND LINE SHELL IS DIFFERENT FROM THE PHP SCRIPT'S ECHO!!!!
