I have this problem using the command ‘last’. My task is to find names of people, that have been logged in at night hours (22:00 - 5:00). So I’ve tried to save the first number (22) to a variable and wanted to compare, but it doesn’t work at all.

This is how it looks like.

@ a =  `last | cut -c 55-56 `

And I’ve also tried this:

@ a =  `last | tr -s “ “ “ “ | cut -d “ “ -f7 | cut -d “:” -f1 `

But none of this worked it always says “Ambiguous” and I really don’t know what I’m doing wrong. I’m new in this and I would be very thankful if somebody helped me. Thank you.

Is this in a shell script or a Perl script or something else? – Kusalananda Oct 25 '17 at 07:27
If the environment is running systemd, you may be better served using journalctl with --since --until and -t systemd-logind – Raman Sailopal Oct 25 '17 at 08:57
careful with those quotes -- they appear to be "smart" quotes here; hopefully your actual command uses "normal" quotes? – Jeff Schaller Oct 25 '17 at 09:58
