Description Mayank 2022-07-30 01:42:50 AEST

Hi

While invoking sftp session, if I ran ls -l command, its shows everything properly (file owner name and its group name), but when I tried to display a specific file, say ls -l file1 , in such case, it used to display file owner id and its group id, as shown below -

# sftp localhost
Connected to localhost.
sftp> cd home/mayank
sftp> ls -l
-rw-r--r--    1 mayank   staff           0 Jul 29 10:37 file1
-rw-r--r--    1 mayank   staff           0 Jul 29 10:37 file2
-rw-r--r--    1 mayank   staff           0 Jul 29 10:37 file3
sftp> ls -l file1
-rw-r--r--    ? 210      1               0 Jul 29 10:37 file1
sftp>


Just want to know if its as per design or its a bug.

Thanks 
Mayank

Seems like a bug, or at least an omission.

ls -l does an SFTP directory listing and prints the SFTP longnames.

ls -l file1 (or also ls -l file*) go through the glob machinery and drop the longname info.

Fixed in OpenSSH HEAD and will be in the openssh-9.1 release due within days.

Note that this uses a protocol extension and requires both the client and server to be updated.
