Need to check a condition using SFTP command
HI,

I connected to a remote FTP server using sftp command.
Need to check if any files are present inside a folder in server directory and then remove if present.

The code should look like this
Code:
[sftp $USER@$HOST<<EOF 2>&1
cd $DIR
mget *$FILEEXT1
Here a condition like (if filecount>0 then )
rm *$FILEEXT1
quit
EOF]

How can this condition be written.

Thanks in advance,

There is no support for conditional expressions in sftp. A workaround for your situation might be to download the list of files, determine the files you wish to delete, if any, and if so do a second sftp to delete those files.

In sftp commands i found '! command ' that can be used to run shell scripts. Can i use this command and execute if condition using sftp, if so how?

Thanks fpmurphy for the reply.
