    Re: need help with grep command

    So I'm guessing the file can look a bit like this - am I right?

    Try one of these two:

    awk '/^TODAY/{want=1} /^TONIGHT/{want=0} want' weathertext5.txt
    sed -n '/^TODAY/,/^TONIGHT/{/^TODAY/!p}'...

    Re: Notes on netplan and yaml

    Is it really? Hah! Evan after using YAML for years I had not noticed (or remembered) that. Clearly I am simply in the habit of typing a space after a colon without even thinking about it.

    My next step would be to check make a note of the IP address and MAC address of each device.

    Can I ask everyone to use sudo iptables-save rather than sudo iptables --list when showing iptables rules. iptables --list does not show all the relevant information - it omits interface names (in...

    [ubuntu] Re: Partitioning like Windows

    Great news.
    It may be worth re-reading the earlier posts now you have seen the basics work, but don't sweat it too hard - you have plenty else to chew on with an unfamiliar OS.

    [SOLVED] Re: specifying filenames correctly

    Start with "ls /home" then "ls /home/peter" etc, expanding until you reach the name of the directory that doesn't exist. That's the name you are mis-typing somehow. You can use <tab> to complete...

    Simplifying things down a bit:
    I will assume that you intend to place one partition of each of your SSDs. I gather you have already installed Ubuntu on first SSD. This gives you a chance to look...

    [all variants] Re: When booting "Must load kernel first"

    That makes me wonder if there is something odd in the EFI boot partition. Is the disk completely free to wipe and start again - i.e. use the live installer to overwrite the first gigabyte or so with...
  14. [ubuntu] Re: Can't seem to configure ethernet on Focal 20.04.3 LTS (Server)

    In ifconfig, two flags are very important.
    Firstly UP is there - that means the OS wants the interface to come up, i.e. it is enabled. Good.
    Secondly, RUNNING is missing. This is the flag that...
