If anyone else is in a very locked-down environment, and you can't even install PuTTY, here's what I do:
Transferring files from Windows to Linux (CentOS 7)
On my Windows computer, open a command prompt
scp [local file to send to Linux] [Linux username]@[Linux computer]:[Linux path to save to]
examples:
scp log.txt ryanLinuxUser@cent.xyz.com:/home/...

I can't speak to the naming of your specific interface, but if you were to set things for say interface eth0, you can add the settings to /etc/systemd/network/eth.network. The settings will then persist.
I did this to enable mDNS. (it meant adding MulticastDNS=yes to that file)

Posting my previous comment as answer (which was just a comment because I wasn't sure whether it would solve the issue entirely):
In an attempted edit on a similar question on SO a potential (and for your case partial I think) solution was mentioned: Running

allows for libc6-dev to be installed which ...

At the moment there is no autostart option, since this application is meant to be desktop agnostic and there is no standard way to achieve this. Fortunately there is a standard way for most Linux/Unix system (those adhering the FreeDesktop standards). However, since the app is meant to become cross platform in future, the option is not available in the app, ...

If they can access the machine by booting into the OS then Full Disk Encryption won't work - in Windows anyway they'll be able to access the documents and saved password files, and even inject their own viruses if they wanted to with an admin account. You'll want to use a file-based (not disk-based*) encryption scheme where you have an encrypted container ...

I do not understand the purpose of legacy mount point.
ZFS provides a hierarchical structure of datasets within a pool. In your case you have a pool named rpool, and at least the following datasets:
rpool
rpool/ROOT
rpool/ROOT/s10x_u10_wos_17b
Each of these datasets is often a filesystem (though it can be a volume / block device instead).
Just as each of ...

AWK can do this by itself, piping multiple processes is not necessary.
awk '{print NR " " gsub(/[{}]/, "")}'
Example:

debian.org has seems to fix this issue. I did this installation about 6 months ago on my Lenavo ideapad 100S-14IBR laptop. However, I installed a debian 10 by upgrading from debian 9.9 and also through a clean installation of debian 10 it seems to work fine now without an issue.
Thanks & Best Regards

If you just want to yank from VIM to Windows, for WSL2 and Ubuntu 20.04, this answer on Reddit worked perfectly for me with standard VIM and standard WSL2 Ubuntu.

How?
How is ssh doing this?
It opens /dev/tty. The relevant line from strace ssh … is:
openat(AT_FDCWD, "/dev/tty", O_RDWR) = 4
The file descriptor 4 is then used with write(2) and read(2).
(Testbed: OpenSSH_7.9p1 Debian-10+deb10u2).

To archive the entire month of January by using the filename (not the file timestamp) you can use:
tar czvf 2020-01.tar.gz 2020-01*.csv
If you want to archive the first and second halves of January separately and you are using a shell that supports brace expansion (eg. bash):
tar czvf 2020-01-A.tar.gz 2020-01-{01..15}*.csv
tar czvf 2020-01-B.tar.gz 2020-...

It does not matter whether Linux is embedded or not. It doesn't even matter whether it is Linux or not. FTP does not let you run commands on the remote system.
You would also need to login to FTP as root to able to access the system config files, and hopefully that is disabled for appropriate security. Really, FTP should be disabled for everybody since ...

You can use the which command to know where any command file is located.

First make sure you have the HIST_IGNORE_SPACE option set, for example in your .zshrc file:
setopt HIST_IGNORE_SPACE
Then you can prefix your print -s "another command" statement with a space to prevent it from being recorded in your history.

Looks like systemctl enable firewalld
turned on my os firewall. So the solution was:
I turned it off and now the connection go through.
To turn off
systemctl stop firewalld
To disable so it doesn't start on reboot I did

It's quite easy to backup a full USB drive. In Linux a USB drive is available as a block device. Partitions are available as block devices as well. In fact they are just fragments of the drive that holds them. The kernel reads the partition table and provides names like /dev/sdx1 or /dev/sdx2, so you (and processes, and the OS itself) don't have to work with ...

After much rummaging, I hit on this solution:
Script /usr/share/initramfs-tools/scripts/init-top/udev runs early in the initramfs boot stage, prior to mounting the root FS and starting systemd proper.

After clicking "START" in Rufus, choose "Write in DD Image Mode" (it will prompt you).

Just to be safe I tried this in mac catalina:
mv '~' '~_bkp'
you can change directory to check the contents
cd '~_bkp'

If its empty simply 'remove'
rm -rf '~_bkp'
'rmdir' can be used too to remove the empty directory

No, there is no generic method of doing this.
Tty devices do not have a built-in screen buffer, and they do not have any built-in understanding of the terminal graphics control codes, either. They're just fancy bidirectional pipes which transfer data between the "host" program (terminal emulator) and the rest (shell and CLI tools).

Not a complete answer, but since you have
A script to find the newer N archives (output to newerN.lst)
A script to find all archives older than N days (output to older.lst)
You can easily produce a list of the old files that are not in the N newer using
grep --invert-match --file newerN.lst older.lst
This list is what you want to erase.

The output shows that you are trying to install a new set of texlive packages with partly new package names. The new packages contain files which are part of the old packages as well, hence dpkg errors out before breaking installed packages.

When you run this on the Pi:
# shell on Pi
export DISPLAY=:0
ssh root@192.168.1.35 /home/enter.sh
you're running export … on the Pi. Then ssh inherits the variable from the shell but it doesn't push its environment to the server. It can set DISPLAY on the server but the variable won't have the value you set on the client (see man 1 ssh, ENVIRONMENT section)...

The packages were installed with independent package names that were different than the .deb files.
dpkg --list | grep packagename | awk {'print $2'} showed me which packages to remove.

I did some experiments and I found that the ssh subsystem is executed by 'sh -c ...' command. Apparently, there is no way to avoid having login shell.

yum is the installation manager for the RedHat family of distros (RHEL, Fedora, Centos). On Ubuntu you should use apt/apt-get:
sudo apt install docker-ce
However, since you seem to run a rather old Ubuntu version (16.04?), you have better install Docker from the Docker repository to get a recent version:
