Software/System engineering is a vast field. It’s like being a doctor for computers. For example, a doctor can be specialized in heart surgery but the same doctor may not be specialized in brain surgery. But it’s very helpful for doctors to know other parts of human body. After all, a human body is a whole system that work together.
I want to know more about computers but there is so much that I can’t remember everything. That’s part of why I’m doing this blog.
I found this web service that allows you to create flash cards. Anki means “remembering or learning by heart” in Japanese. I’m starting to use it because I want to remember more things. I know repetition is the key to remembering things. I don’t remember the command I used one year ago if I don’t use it.
It has iPhone app (which costs money and I bought it) and Android app that syncs with the data on the web service. It lets you repeat the questions you create on the website and/or on the client application that you sync the data with the web service.
I think this is pretty cool. I hope they will improve the UI a bit more. 🙂
Just did find ./ -printf "%f\n" under /bin and got the list of available commands. There are 177 of them. There are commands I don’t know. To build bash muscle efficiently, I should investigate the ones I don’t know. This will be a bit of journey but I will try to remember the ones that are actually useful. At the same time, it’s good to go through all of them just in case.
Let’s talk about scp this time. What is scp? It’s “secure copy (remote file copy program)” It lets you “copy files between hosts on a network.” I’m going to write an example to upload a file to a server.
Alternatively, you could specify -r option to copy the entire directory recursively. Here is what the man page says. “Recursively copy entire directories. Note that scp follows symbolic links encountered in the tree traversal.”
scp works well when you are just dealing with Mac or Linux but you may find it not so easy from Windows. I personally used WinSCP to transfer files from Windows to Linux machines.
I just checked Git Bash on Windows and yes scp is available. Git Bash is actually giving us pretty good tools for Windows users. (I’m no longer full time Windows user anymore… as I use Linux Mint as my main desktop.)
