QUESTION
I'm a Java Developer who is trying to learn HTML in painful baby steps. I'd like my nacent website to run a simple bash shell script (or better yet, a PHP script) when the user clicks a button or hyperlink. It is surprisingly hard to find a simple example of this!
I found this example on StackOverflow. The post's second answer lays out a step-by-step example, where the HTML code calls a PHP script; the PHP script calls a bash shell script. I've tried to replicate the example on my own web server. (FYI, I'm developing on an Ubuntu machine running Apache2.)
Here's my index.html:

Answered 2022-Mar-25 at 16:48I think that could enable CGI scripts in your webserver, send the script to /cgi-bin/ folder, rename it to myscript.cgi (remember to put the appropiate Shebang), set 0755 permissions, correct owner/group and put in the very beginning of the script:

I am trying to extract some information from a Hive table and when I run a describe db.tablename statement within impala-shell, I see that the output is ~2000 lines.
How can I extract this information into a local file without exiting the interactive mode? I could only find references to do it by passing the -o parameter when launching impala-shell

I just discovered mapfile in bash when shellcheck recommended it to my code to capture two shell parameters from a space-delimited string of two words. But, mapfile does not seem to function consistently. For example, this works as expected:
...ANSWER
Answered 2022-Mar-07 at 03:00Technically the array is being populated; the issue is that mapfile is called in a sub-process which, when it exits (back to the command line) the array assignment is lost, ie, you can't pass assignments 'up' from a sub-process to a parent/calling process.
Try these instead:

While trying out the answer provided in this question on how to check if a GitHub repository exists using bash, I notice that the command asks for credentials and throws an error if the repository is not found:
...ANSWER
Answered 2022-Feb-10 at 16:39In order to easily check if a public repository exists on GitHub, you actually need not git nor any credentials: you can make a simple HTTP request to the GitHub REST API.

I define case class in spark-shell or scala-shell, and found its constructor signature is changed, there's one extra parameter $iw added, what is that? why that happens? This issue caused me unable to create new instance via its constructor in reflection
ANSWER
Answered 2022-Feb-08 at 18:47This is expected behavior in both scala-shell and spark-shell after scala 2.12. If you just use spark-shell for quick experiments, you could try spark 2.4 which relies on scala 2.11. For prod, you still can build your package by using relection on case case contructors.

QUESTION
I am trying to run a simple command that initiates a port forward before the execution of my automated tests but it hangs every time.
The end goal was to setup the port forward, get the PID and terminate the port forward, at the end of the session.
I am on macOS and using Python 3.9.7 and trying to execute this inside of PyCharm IDE.
Here is the code snippet:
...ANSWER
Answered 2021-Nov-17 at 12:36The main problem here is with the communicate. You just want to Popen the process, then leave it running until you kill it.
You will definitely want to avoid shell=True when you can; see also Actual meaning of shell=True in subprocess
I don't see that the stdout and stderr redirections are useful either. If you just want to run it quietly, probably just redirect to and from subprocess.DEVNULL instead.
Creating a separate session seems dubious here; I would perhaps drop that too.
Running Bash commands in Python has some guidance for which subprocess method to prefer under what circumstances. TLDR is subprocess.run for situations where you want to wait for the process to finish, subprocess.Popen when you don't (but then understand your responsibilities around managing the object).

...ANSWER
Answered 2021-Nov-10 at 22:32Okay, I finally found one option that helps dramatically. The default docker output is neat and all, but it gives you one line of info in color and no details at all of what happened in your RUN command unless an error occurs (error which gets printed at the end).
In order to debug, you can at least get the output of each command using:
