[Bug 1019316] Re: ls gives incorrect directory listing

[jan5000]

Thanks for that. Interesting.
I have a script (called "clean") which manually removes some of my application directories and their contents (i.e. the EXPORT directory, and subdirectories) , and I have a program (which I wrote)  which when it starts will recreate a new EXPORT directory, and subdirectories if they don't exist. Depending on whether you run ls from a new terminal or one which has been around for a while, and depending on when you run the clean script or program, you sometimes get unexpected results in terms of directory listings in terminal windows which don't reflect what actually happened in the directory moments before.

 I must admit I am concious of not trusting (a bit strong, I apologise)
ls (when I am developing my application), unless I either bounce to the
parent and back again (i.e. as per my report ), or I cd to it from a new
terminal. It's very difficult to explain because it's inconsistent. But
I see from your example you've illustrated similar ls behaviour.

Can you explain: "This is expected, and not an error".  You would have
thought that all termnials (and ls running on each termianl) would keep
"in sync" with any changes to the directory which may occur from other
terminals or indeed (in my case) other programs or scripts, and report
the "truth", As a "Windows lover" said to me yesterday (tongue in cheek)
"That wouldn't have happened on Windows 7". Sadly (as a Linux
application developer / Windows 7 (when I have to) user) I did not have
any defence to offer...
