Today I will be showing you how to use the read command as-well as some read command examples.
In this post I will show you how to use bash redirection to write to a file using the cat command. This is a very simple trick that you can use for all sorts of things when it comes to bash scripting including setting up certain configuration files when more powerful options aren’t available or aren’t worth using. You can also use this in your bash scripts to create files from scratch if need be without having to have separate files or download them remotely.
In this post I will be showing you how to use some of the basic loop functions available in bash scripting. These loops (especially a basic for loop) come in handy and are used pretty much daily for me. You can run these loops directly from the terminal, you do not need to actually save them as a script to execute them which makes them even more useful. I will get into using loops to iterate through arrays and other useful tricks on a later post so keep an eye out if you liked this one! =)
Today I will be showing you how to use a basic expect script inside of your bash scripts for automation. Expect works just like the name sounds, expect to see a prompt or other piece of text and then send the response. With this you can do things such as automatically entering password for SSH (not recommended for daily use), automatically answer prompts, etc.
