Re: Strange behaviour with tail command

Well ,... Tankyou, my script now works well.
But i still think it's a bug. The old style compatibility is meant to accept options like "tail -20", without "-c". This explains also why -c -2 works, and not -c +2.

Re: Strange behaviour with tail command

So in the slackware/salix version the use of -c +XX is invalid? If so, why compiling without the slackbuild generate a working binary?

Re: Strange behaviour with tail command

Found a workaround...
Downloaded coreutils 9.3 + slackbuild from slackware current source tree, compiled but the issue remain, but if compile outside the slackbuild, from a vanilla source, the resulting tail works as expected. So hase to be something related to the patch the slackbuild introduce.
