I can't concatenate ssh to a server from another server

Question

I want to get the last folders name from a pi and this commands works just fine:

ssh [email protected] 'ls -t /media/usb/Pictures/new/ | head -1'

Returns: 230125_1356

To retrieve the number of files in that folder I'm using:

ssh [email protected] ls -t /media/usb/Pictures/new/$(ssh [email protected] 'ls -t /media/usb/Pictures/new/ | head -1')/ | wc -l

Returns: 5

But now I'm trying to get the same results from another pi connected to the first one: This one works fine and gives me the name of the last folder:

ssh -t [email protected] ssh [email protected] 'ls -t /media/usb/Pictures/new/ | head -1'

Returns: 230125_1356

My problem arises when I try to get the number of files inside the last folder over the second pi with:

ssh -t [email protected] ssh [email protected] ls -t /media/usb/Pictures/new/$(ssh -t [email protected] ssh [email protected] ls -t /media/usb/Pictures/new/ | head -1)/ | wc -l

Returns: 1

The return should be 4 which is the number of files in that folder.

Any help will be much appreciated. Thanks.

Consider using something like `sshfs` if you do this a lot. [Parsing the output of `ls` should be avoided.](https://unix.stackexchange.com/questions/128985/why-not-parse-ls-and-what-to-do-instead) — Panki, Jan 26 '23 at 07:57
Thanks Panki for your answer, I've tried this command and it doesn't work, I can't see the mounted filesystem in the mounted point. ```sudo sshfs -o sshfs_debug [email protected]:/ /mnt/field_laptop``` SSHFS version 2.10.0 [email protected]'s password: Server version: 3 Extension: [email protected] <1> Extension: [email protected] <2> Extension: [email protected] <2> Extension: [email protected] <1> Extension: [email protected] <1> — Mark, Jan 26 '23 at 14:11
