[Apr 05, 2010]  Problem with rmlines

As of April 4 this problem was not independently verified, but caution in usage of script is recommended.

I have used rmlines (; but found it to be faulty. Though it worked on my test case, a larger file contained a number of lines that were processed erroneously. I have send a mail to the developer, who wrote back he had no time to look into the (confirmed) problem. On request, I can offer all details, test case, etc. My personal suggestion would be, to remove the link.

Here I used it for administrating a large production server, and it missed out on about 2-3% of the occurrences; to my dismay (and the frustration of my users).

Thanks again, Uwe
