Copy files and folders using SCP with spaces in path

Copying data from one system to other with file or folder names that contain spaces in path can be achieved using this guide. In this case I am copying data from Macbook to Windows 10 computer. In order to copy the data easily it is better to use bash commands. Windows computer can support WSL (Windows subsystem for Linux) and you can run one of few linux distributions to use shell commands. I have Ubuntu set up within my Windows 10 using WSL. If you do not have WSL, you can set it up using my guide here . The copy can be performed in two ways: 1) Using SCP Source (MacOs) path: /home/Users/username/Documents/data extract from 2020/ First of all you add escape sequence to the path so it will become:  /home/Users/me/Documents/data\ extract\ from\ 2020/ . While this works on local system for SCP you'll have to double the escape sequences by replacing \ with \\, as below. Figure out your source computer IP address using "ifconfig" command. Now using scp command on target syst

VMWare ESXi 6.5 HP Custom Image Upgrade to v6.5U3

I had been escaping the Unhandled Exception error every time I log into my ESXi standalone server running v6.5 on N54L and can't be upgraded to v6.7 due to process compatibility. I have finally found the HP Custom image updated to v6.5U3 which appeared to have the fix built into it. It was quite straightforward update using the l latest 6.5 HP image so as habit I am making notes here for myself and everyone else who may find it useful. First of all I downloaded HP Custom v6.5U3 image  by selecting Offline Bundle. I then placed it in my datastore e.g. ds001. Once copied I ran following command line after I was connected to ESXi using ssh. # esxcli software vib update -d /vmfs/volumes/ds001/ This command took few seconds or may be minutes but confirmed that updates have been installed and will take effect after reboot. So I rebooted the host and it worked like magic. # reboot I did not place host in main

Linux within Windows 10 (bash instead of cmd) - WSL

Linux within Windows 10 Whether you are a Linux/ Unix user, don't find Windows friendly or want to run simple clever stuff in bash shell that Windows shell simply cannot handle, you'll love it. Windows 10 has built in Windows subsystem for Linux delivering native support for Linux features. This is not a virtual machine running in any hypervisor program, no Hyper-V, VMWare Workstation or Oracle Virtualbox required. Because it works natively you also have access to windows drives and directories which is very useful if you want to run any scripts or even grep or awk type commands on files in your windows directories. So how do you do it? It is very simple and here are the steps you have to carry out. Press Windows+R and enter " OptionalFeatures " in Open box and click OK to run. From Windows Features form select "Windows Subsystem for Linux" and hit OK. Wait for it to find required files and complete installation. Select Restart and wait for it

Bash script and characters that require to be escaped

There are few ASCII characters that need to be escaped when using in certain bash scripts especially when echoing or passing value through variables.
