The following commit causes a regression here: commit a4c41bf3fa905c38e6e4d159c13eed890d53838b Author: Lennart Poettering <lennart@poettering.net> Date: Thu Mar 7 21:28:09 2013 +0100 pager: always override LESS https://bugzilla.redhat.com/show_bug.cgi?id=868383 Primary reason to do this is to ensure "-e" works as intended, and is not ignored because the user set his own LESS variable. I used to run LESS=R journalctl -ab (or LESS=RS, or ...) to change the behavior of the piper to my needs. Mainly allowing me to use my mouse wheel to scroll faster through the logs. With systemd 198, I am unable to override LESS to achieve that goal. As a workaround, I can use journalctl -ab | less -R, but then I lose colors. Please allow overriding LESS again, fixing bug https://bugzilla.redhat.com/show_bug.cgi?id=868383 can be done by educating the user not to do stupid things with $LESS and/or by checking whether $LESS is empty or not.
The pager can be overridden with $SYSTEMD_PAGER [1]. [1] http://www.freedesktop.org/software/systemd/man/journalctl.html#%24SYSTEMD_PAGER
Yeah, I eventually figured that out, but `LESS= SYSTEMD_PAGER=less\ -FRSM journalctl` still does not work because `$LESS` is set unconditionally. Therefore, I am using this wrapper: # ~/.bashrc export SYSTEMD_PAGER=${SYSTEMD_PAGER:-$HOME/bin/less-systemd} #!/bin/sh # ~/bin/less-systemd # systemd uses: FRSXMK # F --quit-if-one-screen # R --RAW-CONTROL-CHARS # S --chop-long-lines # X --no-init # M --LONG-PROMPT # K --quit-on-intr export LESS=FRSM exec -- less "$@"
