Description Juliano F. Ravasi 2009-12-25 21:12:18 UTC

Version:           1.3 (using KDE 4.3.4)
OS:                Linux
Installed from:    Ubuntu Packages

When the embedded terminal is open and you change the directory in dolphin, it sends "cd $DIR" to the terminal (where $DIR is the target directory).

If the directory name contains some reserved shell characters, like spaces, asterisks or question marks, $DIR is properly quoted. But if the directory name contains '[' or ']', which are also special shell operators (wildcard), the argument doesn't get quoted.

To reproduce:
1. Create two directories: "abc" and "ab[c]"
2. Click on "ab[c]"

Result:
* Dolphin sends "cd ab[c]" to the terminal, going into directory "abc".

Expected behavior:
* Dolphin sends "cd 'ab[c]'" to the terminal, going into directory "ab[c]".

Comment 1 Juliano F. Ravasi 2009-12-25 21:21:32 UTC

After doing some more tests, '!' has the same problem. Most interactive shells use '!' as a history recall shortcut.

To reproduce:
1. Create a directory named "!!".
2. Change to it.
3. See what happens in the terminal.

While you are at it, it should also be a good idea to add '~' to the list of characters that trigger quoting.

Recap: add '[', ']', '!' and '~' to the characters in the directory name that trigger the quoting of the parameter to 'cd' sent to the terminal.

Thanks a lot Nicolas. Might it be possible that you submit your patch at the review board (http://reviewboard.kde.org)? The patch looks good IMO, but it would be good if more kde-core developers have a look on this... Thank you!
