ftp - check if file on remote exists (skip overriding)
 

Hello,

I have a script that uploads a file from local to remote place using ftp. The problem is that, if on remote host there is a file called the same as the one I want to upload, the ftp program overrides that file. But I don't want to override nothing (even if the remote file is older, smaller or whatever).
The problem is that I can't test if a file exist on remote (doing [ filename ]) because ftp only allows me limited commands (like ls, mkdir, cd, etc.)

So, how can I check if the file i want to upload already exists, so I can skip overriding ?
Notes :
- Using sunique feature isn't a solution. I don't want to copy nothing if it's there already.
- Maybe using other ftp programs might help, but what programs ?


Thx,
Adrian

Try lftp.

You could give "lftp" program a try.
Why dont you try "getting" the file first, if its successful remove it locally, else upload.

I've tried lftp too. But it too doesn't have the option of testing the existence of a file prior to uploading(or I haven't figured out).

"Why dont you try "getting" the file first, if its successful remove it locally, else upload." -> I've toughed that , but like a last resort, I am looking for a more elegant solution. What if the file has 4GB ? No, this will be the last solution.

Hey ghostdog74, it seems this is good. But I have a question : how to specify the whole path of the file on the remote ? E.g.: I want to check to see if /httpdocs/sounds/cool.wav is there. How will the code change ?

Thx
