Join Scott Simpson for an in-depth discussion in this video Getting input during execution, part of Up and Running with Bash Scripting.
…So, you just saw how to get user input at the command line, but sometimes it's…not practical to have all of the values…you're looking for specified when you run the script.…Luckily, there's a way to get input during the execution of a script.…I'll write a typical question and then write read name.…The read keyword pauses the script to wait for input.…Followed by return or enter, and it stores that input in the variable you specify.…Here, I've used name.…There are also some options that read can accept.…Let's ask for a password, and here I'll use read -s followed by a variable name.…
The -s means silent, which means that it won't show the characters that I type in.…I can also write everything on one line with a…-p option, which writes out a prompt before the input area.…And let's echo all that out just to see what's going on.…And if I run this, first I'm prompted for my name.…And then my password, which you can see is…not appearing when I type, and then our inline prompt.…What's your favorite animal?…I like cats.…
