I should say I'm only an amateur at this. The following gets homework files from my webpage. Works well.

rsync -av --progress -e 'ssh -i ~/.ssh/godaddy5_rsa' $user@$server:${RemotePath}/ "${Answers}"

All the file names look like this:

1112223334_18BEwW4data

First student number (1112223334), then _class (_18BE), then week number (wW4 = winter term Week 4) plus data

The paths are:

RemotePath="public_html/18BE/php/uploads"
Answers="/home/pedro/winter2019-20/18BE/fastmarker"

Of course, as the term proceeds, wWX will change. I made a little bash script to get the week number and inserted it in my script for rsync:

echo "First, enter the week number you want to get."
read week
echo "You are fetching winter week $week"
echo "If this is correct, enter y, if not enter n to abort."
read answer
if [ $answer = "n" ]; then
echo "You entered the wrong week number, aborting script, byebye. Start again!"
 exit
fi
echo "You entered the correct week number, I'll carry on!"

Now I want to only get files which have $week in the name, for next week that will be wW4.

I have been reading the rsync manpage and trying all kinds of combinations of --include and --exclude

All I ever get is either nothing or all files, i.e. files which also have wW1, wW2 and wW3 in the file name.

How should I tell rsync to only get files with $week (next week will be wW4) in the name??

EDIT: Thanks for the suggestion. I tried this:

rsync -av --progress -e 'ssh -i ~/.ssh/godaddy5_rsa' $user@$server:${RemotePath}/*_18BEwW4data "${Answers}"

Sadly, I get nothing. I need a wildcard for the student numbers, because they are all different.

I renamed some file to end in *.wW4 then I tried this:

rsync -av --progress -e 'ssh -i ~/.ssh/godaddy5_rsa' $user@$server:${RemotePath}*.wW4 "${Answers}"

I get this error in bash:

Third, get the files from the remote server to this computer. receiving incremental file list rsync: link_stat "/home/myusername/public_html/18BE/php/uploads*.wW4" failed: No such file or directory (2)

SORRY! My fault! I had a mistake in the $RemotePath it works now!

Thanks, and sorry to bother you!

rsync -av --progress -e 'ssh -i ~/.ssh/godaddy5_rsa' $user@$server:${RemotePath}/1112223334_18BEwW4* "${Answers}"

Don't overthink this, you don't need include/exclude, you just need wildcards.

You really don't need even to figure out the week since you can just have a directory that has all the assignments in it, and rsync will just grab the newest, like so:

rsync -av --progress -e 'ssh -i ~/.ssh/godaddy5_rsa' $user@$server:${RemotePath}/1112223334_18BEwW* "${Answers}"

date +%U will return the week of the year, so you can use that to generate automatically the week of the course, assuming it's linear, incrementing 1 every week. Or you can make an array where the indexes point to the course week number, and the indexes are the year week number. Or if it's a linear relation, you just add/subtract whatever to the year week number.

  • Thanks, but that did not work for me. I need a wild card for the student numbers, because they are all different. – Pedroski Sep 21 '19 at 8:12
  • You didn't say that you needed different student numbers. Then just replace any part you want to be wild carded with a wild card. $user@$server:${RemotePath}/*_18BEwW* or whatever. When asking the question, the more precise you are about is actually required, the easier it is to answer it fully the first time. – Lizardx Sep 21 '19 at 21:51
