OK maybe I was just looking at the latter half of $ sh O /tmp created directory '/var/tmp/y' copied 'x/1' -> '/var/tmp/y/1' copied 'x/2' -> '/var/tmp/y/2' copied 'x/3' -> '/var/tmp/y/3' copied 'x/4' -> '/var/tmp/y/4' copied 'x/5' -> '/var/tmp/y/5' copied 'x/6' -> '/var/tmp/y/6' copied 'x/7' -> '/var/tmp/y/7' copied 'x/8' -> '/var/tmp/y/8' copied 'x/9' -> '/var/tmp/y/9' removed 'x/9' removed 'x/8' removed 'x/7' removed 'x/6' removed 'x/5' removed 'x/4' removed 'x/3' removed 'x/2' removed 'x/1' removed directory 'x'
$ cat O set -eu cd /tmp mkdir x cd x seq 9|xargs touch cd - mv -v x /var/tmp/y
