jekyll tty2 Mon May 14 2018 20:24 - 20:24 (00:00)
wtmpclean -f /var/log/wtmp.1 --raw jekyll
jekyll [03539] [tty2 ] [tty2] [ ] [0.0.0.0 ] [2018.05.14 20:24:08]
# replace a single record, using a regular expression
wtmpclean -f /var/log/wtmp.1 -t "2018\.05\.14 20:.*" jekyll nosuchuser
> wtmpclean: unknown/bad user `nosuchuser'
wtmpclean -f /var/log/wtmp.1 -t "2018\.05\.?? 20:.*" jekyll hide
> /var/log/wtmp.1: 1 block(s) logging user `jekyll' now belong to user `hide'.
# remove all the occurrences of the user `hide'
wtmpclean -f /var/log/wtmp.1 hide
> /var/log/wtmp.1: patched 3 block(s) logging user `hide'.
