            Bug ID: 380881
           Summary: Bash interprets COMMAND {folder}/.* as COMMAND
                    {folder}/..
           Product: konsole
           Version: 17.04.0
          Platform: Neon Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: datenela at gmail.com
  Target Milestone: ---

This is my very first bug entry. Maybe this is normal behavior. But I never
saw this on other Linux machines before (Trusty 14.04 for instance).
Please ask back if something is unclear.

I wanted to chown hidden files in a subdirectory with
chown {user}:{group} -R {folder}/.*

The result was, that all folders and subfolders in . have been touched too.

Same happens with rm -R {folder}/.*. But removing was refused because I
was in ./

That means, {folder}/.* is interpreted also as {folder}/..

Please try:
cd /tmp
mkdir test
mkdir test/test
mkdir test/test/folder1
mkdir test/test/folder2
touch test/test/.hiddenfile
touch test/test/folder1/.hiddenfile1
touch test/test/folder2/.hiddenfile2

cd test
pwd
/tmp/test/test
ls -lath /tmp/test/test
drwxrwxr-x 2 test test 4,0K Jun  6 11:05 folder2
drwxrwxr-x 4 test test 4,0K Jun  6 11:05 .
drwxrwxr-x 2 test test 4,0K Jun  6 11:05 folder1
-rw-rw-r-- 1 test test    0 Jun  6 11:05 .hiddenfile
drwxr-xr-x 3 test test 4,0K Jun  6 11:04 ..


# change folder1 and subfolders to testgroup
chown test:testgroup -R folder1/
ls -lath
drwxrwxr-x 2 test test      4,0K Jun  6 11:05 folder2
drwxrwxr-x 4 test test      4,0K Jun  6 11:05 .
drwxrwxr-x 2 test testgroup 4,0K Jun  6 11:05 folder1
-rw-rw-r-- 1 test test         0 Jun  6 11:05 .hiddenfile
drwxr-xr-x 3 test test      4,0K Jun  6 11:04 ..


# change folder1 and subfolders to testgroup
ls -lath folder1/
drwxrwxr-x 2 test testgroup 4,0K Jun  6 11:05 .
drwxrwxr-x 4 test test      4,0K Jun  6 11:05 ..
-rw-rw-r-- 1 test testgroup    0 Jun  6 11:05 .hiddenfile1


# change folder1 and hidden files to testgroup
chown test:testgroup -R folder1/.*
drwxrwxr-x 2 test testgroup 4,0K Jun  6 11:05 folder2
drwxrwxr-x 4 test testgroup 4,0K Jun  6 11:05 .
drwxrwxr-x 2 test testgroup 4,0K Jun  6 11:05 folder1

As the KDE Neon Dev stable installation is a test installation I cannot
guarantee that I'll have this system still installed when you answer me.
The history should be reproducible.

The installation is a fresh install with a low latency kernel, five or siy
small packages from KXStudio repo installed and with upgraded packages.

ISO: neon-devedition-gitstable-20170605-1854-amd64.iso
