these are more recipes, or even just sample of CLI that works in real life. daughter machine : Model T440s Type 20AR serial PC00L2HW[1] , 8G Ram (4G Soldered) 500G sHDD, Transcend 256Go SATA III 6Gb/s MTS430S 42 mm M.2 SSD 430S SSD TS256GMTS430S (instead of 3G Sim transmitter)

Mount nfs
from Nautilus
nfs://192.168.xxx.xxx:0/<Share to mount>
from terminal
# mount 192.168.xxx.xxx:/<share to mount> ~/<destination folder/
the t=nfs doesn't seems to be needed most of the time
Query by size
From here
du -h $(du -b * | sort -n | cut -f2-)
Scan from network
Need reportlab, hplip, python imaging library. And possibly to run hp-setup -i just to wake things up.
[jph@ThinkDMX3 ~]$ hp-scan --device='hpaio:/net/OfficeJet_7510_series?ip=<ip address without port>' --output=output.pdf
When all said and working, scan in color at 300DPI with :
hp-scan -m color --size=A4 -o /dest/of/file/NameOfFile.pdf
Boot GRUB manually when failing to locate your kernel (use tab to fill)
Check disks available: grub> ls define root system: grub> root=(hd0,msdos1) Load the kernel image: grub> linux /boot/wmlinuz root=/dev/sda1 !! This could be, not sure, use Tab to autocomplete: grub> linux /boot/wmlinuz-linux root=/dev/sda1 Locate initial ramdisk: grub> initrd /boot/initramfs-linux.img Boot the damn thing & now tell me why GRUB isn't just doing it by itself grub> boot

Also, upon install, don't save your grub config file as grub.conf...
Cleanup pacman's cache:
paccache -r[2]
Query both battery states
upower -i $(upower -e | grep 'BAT1') | egrep 'BAT1|energy' & upower -i $(upower -e | grep 'BAT0') | egrep 'BAT0|energy'
Add it as alias in .basrc as
alias BATT="upower -i $(upower -e | grep 'BAT1') | egrep 'BAT1|energy' & upower -i $(upower -e | grep 'BAT0') | egrep 'BAT0|energy'"
Needs double quotes because of the use of single quote in the command
WebDAV to ownCloud
Syntax for Nautilus access through WebDAV towards an owncloud instance :
davs://adress.ofyour.cloud/remote.php/dav/files/nameofuser
this will prompt for a username and password and bring you to the root of the File side of things, which is useless. Your actual share is network adress / files /username, not the visibly mounted network share that ony goes to adress.ofyour.cloud/remote/dav (which shows a bunch of stuff you can't do a thing to. be sure to bookmark it the real ./files/usermane location. The system creates a username and impossible password for you, be sure to not use the generic host creds. The actual line for me is davs://tic.<myserver>.net/remote.php/dav/files/<username as generated>
Force IPV4 GPG keys renewal / finding
IF it's just "missing keys" or "invalid" or such, try :
# pacman-keys --populate archlinux
or
# pacman-key --refresh-keys
Or the caveman way :
# pacman -S archlinux-keyring
If in yay, try this :
# gpg --keyserver keys.gnupg.net --recv-keys <insert key number here>
Or this for TOR for instance :
# gpg --auto-key-locate nodefault,wkd --locate-keys torbrowser@torproject.org
If #pacman -S archlinux-keyring fails after a global $yay -Syu aborted with some gpg keys gibberish, try this:
Fight stupid GPG keys that won't update other than over an IPV6 address :
I ran into this problem on MacOS 10.13.6, and I currently suspect it's something weird with gpg deciding to use IPv6. I currently don't have a valid global IPv6 address, so all IPv6 addrs should be "no route to host", but I noticed that if I manually look up keys.gnupg.net and substitute in one of the IPv4 addresses explicitly, then the command works and I can proceed, without doing the other workaround with curl. $ gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB gpg: keyserver receive failed: No route to host $ host keys.gnupg.net keys.gnupg.net is an alias for hkps.pool.sks-keyservers.net. hkps.pool.sks-keyservers.net has address 51.38.91.189 [...] hkps.pool.sks-keyservers.net has IPv6 address 2001:67c:26b4::98:0 $ gpg --keyserver hkp://51.38.91.189 --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB gpg: key 105BD0E739499BDB: 4 signatures not checked due to missing keys gpg: key 105BD0E739499BDB: public key "Piotr Kuczynski <piotr.kuczynski@gmail.com>" imported gpg: key 3804BB82D39DC0E3: 101 signatures not checked due to missing keys gpg: key 3804BB82D39DC0E3: public key "Michal Papis (RVM signing) <mpapis@gmail.com>" imported gpg: no ultimately trusted keys found gpg: Total number processed: 2 gpg: imported: 2
