Hello,
I am new to shell scripting but I am attempting to create a script that connects to an ftp and downloads a folder of files. It then compares the downloaded folder on the local machine to another local folder. I am not sure how to work the compare function at the moment i was looking into diff's. I would also like to record the differences to a file i am also not sure how to do this. Here is what i have so far i was hoping someone could help or point me in the right direction.

Ok i seem to have the diff script working on its own and it records the differences to a file. How would i go about combining my ftp script and my diff script because if i end the ftp script it closes out the script entirely.

I hope this is what you wanted ???
EOF Checks for end-of-file condition on open file hence close the file and then use diff.

cksum is a fast way to see if two files are the same.
However, ftp-ing folders of files over just to compare files is a waste of bandwidth and time. What exactly are you trying to do - not how, but what do you need to acheive?
