When I installed 2.1 HP-UX, the behavior of the pr command changed.
Pr now inserts unwanted tab characters into files that contain
8-bit character codes, when outputting more than one column.
The enclosed shar contains an example, just unwarap it in an empty
directory.

Thank you for reporting this problem. The problem appears to be in the terminal I/O driver rather than pr. If you use stty to set the output mode "tab3" (expand spaces to tabs), a simpler instance of the problem is shown by: $ echo '888\t7' (replace "888" by 8-bit characters) 888 7 $ echo '777\t7' 777 7 The 8-bit characters are apparently not being counted when a tab is expanded for display. A workaround for your problem would be to use stty to set the tab output mode to "tab0". I will forward this problem to the appropriate folks. Wayne Krone Hewlett-Packard
