Hmmmm. Sounds like it's time to see what the hell is going on over at the FSF. Such a thing should DEFINITELY not be the default behavior, but turned on only by an environment variable or command line flag.

Many versions of ps truncate lines at a certain length if they can't determine the terminal size. Use the "w" option to stop the truncating : -w Wide output. Use this option twice for unlimited width. w Wide output. Use this option twice for unlimited width. HTH's Crouse On 2/12/08, Anders Johansson <ajh@rydsbo.net> wrote:

I know that, I even said so. That's not what's happening here. Now it's started truncating individual fields (in this case the name of the program), instead of truncating the whole line This is not something it has done before Anders -- Madness takes its toll -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

It seems it's just trying to be clever. The examples you gave were of applications that were swapped out, so ps doesn't have access to the real command line and instead prints only the program's base name as recorded in the process table. This is signified by enclosing that name in square brackets. The cleverness, such as it is, then, is not discarding the trailing square bracket and truncating the string inside the square brackets. And as ever, when run through a pipe, a default width must be used, since the output is not going (directly) to a terminal.
