[Pkg-samba-maint] Bug#985718: smbclient: first recurse command in a command string sets recursion ON even if the command is recurse OFF

[Wim Bakker]

Package: smbclient
Version: 2:4.9.5+dfsg-5+deb10u1
Severity: normal

Dear Maintainer,

I copied a script containing the recurse ON command. Instead of removing it I changed it to
recurse OFF. To my surprise this didn't switch off the recursion. Only after removing the
recurse OFF command did the recursion on the dir command stop. An explicit recurse ON;recurse OFF
also worked. This behavior is unexpected and may confuse an unaware user who copies a script
and modifies it.

I tested it on another system with smbclient version 4.11.6-Ubuntu and this bug is still there.
