I'm not able to reproduce with 12.2:
/suse/werner> stty size 42 81 /suse/werner> ps axfl | wc -L 173
that is that the longest line of the ps command is 173 but the XTerm has only 81 columns. Do you have some environment variables set that are accordingly to the manual page of ps:
COLUMNS
and do have installed all available updates for OS 12.2? Just do a
grep -rs /etc/profile.d/
to see where the variable COLUMNS is set.
Hi Werner 12.2 11.0 ------------------------------------------------ stty size 55 236 55 236 ps axf | wc -L 236 344 echo $COLUMNS 236 236 COLUMNS isn't set anywhere in /etc/profile.d/ (on either system). The line that isn't being folded when piped through grep is 293 long: dupont5:~ # ps axfww | grep spamd | wc -L 293 I've just now updated again - this is the list of updates: coreutils findutils glibc glibc-devel glibc-extra glibc-locale iproute2 iptables libiptc0 libopenssl-devel libopenssl1_0_0 libxtables7 openssl sysconfig systemd systemd-sysvinit xen-libs xen-tools-domU After reboot - no change in behaviour wrt this issue. FYI, I'm accessing both systems via ssh from a Konsole window. I don't know if that makes a difference. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Found that enforcing the bash shell option checkwinsize will cause that the variables COLUMNS and LINES become exported variables instead of internal ones. In SR #47584 I've removed enforcing checkwinsize and in SR #147585 I've added # If COLUMNS are within the environment the shell should update # the winsize after each job otherwise the values are wrong case "$(declare -p COLUMNS 2> /dev/null)" in *-x*COLUMNS=*) shopt -s checkwinsize esac in /etc/bash.bashrc for interacrtive shells as this helps to avoid wrong COLUMNS and LINES if during a forground job in the bash the terminal has changed its columns and/or lines. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
