ls command error via SFTP in Linux shell script

i have the next code:

files=$(lftp -u mgtwrk35,Unix11! sftp://illin634<<EOF
cd some_dir
ls | tail -1
EOF)

why does the code above work, but if i add to the ls function -tr like:

ls -tr | tail -1

it doesn't work and gives me the next message:

ls: invalid option -- t
ls: invalid option -- r

Thanks in advance for the answer

The ls in lftp is not the real thing. It's also named "ls" but does not support all the parameters you can find in the standard ls.

  • find lets you recursively list files.
  • cls --sort=date lets you sort by modification date.

I don't know how to combine the two. There's a work-around mentioned by Nicolas Noble, which is to use awk to post-process the result of find.
