warranty | Script to estimate warranty expiration for macs

Assuming what I mentioned in my comment on your question, the fix is just to simplify your FieldWithConfidence type significantly. Right now it is trying to add a number of additional levels of structure beyond what you seem to want. Here is a version of that type that works as I think you intend:

Instead of having where WARRANTY_IN_YEARS>3, your question states

...only if the average warranty of the manufacturer is more than 3 years

The key word is AVERAGE.

To filter based on an aggregate function, you will need to use the filter in your HAVING clause and not your WHERE clause like this:

As mentioned by @oguz_ismail in the comments, bug-bash@gnu.org is the appropriate place to report the bug.

However, a certain format for the email is required/requested, when you need to report a bug.

All bug reports should include:

• The version number of Bash.
• The hardware and operating system.
• The compiler used to compile Bash.
• A description of the bug behaviour.
• A short script or ‘recipe’ which exercises the bug and may be used to reproduce it.

You can find ALL the details at: https://www.gnu.org/software/bash/manual/html_node/Reporting-Bugs.html

Finally, there is a helper script built into bash itself. Call bashbug from the command line, and it will populate most of the requirements, leaving you to fill out the description and the steps required to reproduce the bug.

Unlike C# or JavaScript, or wherever it is you're coming from, Nil and null in PureScript are not a special/magic "uninitialized reference" sort of thing. PureScript doesn't have those at all. Everything is always "defined", as far as the PureScript compiler knows.

Nil is just the name of a List constructor. Take a look at the List definition:

GNU sed is locale aware. If you want to work with raw bytes (ie. you can check what bytes represent " in Shift_JIS and feed that to sed) use:

You have several problems here:

1. ifneq (${exist},"") will fire the error if ${exist} is not equal to "", which is the case. Try ifneq (${exist},).
2. ls --version sends its output to the standard output, not the standard error, so in your case, with ls --version, exist will not be the empty string. It will be something like ls (GNU coreutils) 8.32...
3. What you're doing is a strange mixture of make and shell constructs. Make recipes are shell scripts. There is no need to call the shell make function in a recipe. You should maybe try to write a make macro with 100% shell content (including shell variables if you need some). Do not forget to escape the make expansion if needed.

You could try something like (not tested):

As you found, this function is defined in the libcrypto library, but you did not actually link with that library. You need to add -lcrypto to the end of your linker command line.

The -L option specifies a directory to be searched for libraries requested with -l options, but does not itself add any libraries to the link.

Think of the brackets syntax [] for the destructing operation as an index to a property of an object, not an array that you pass in. It's analogous to calling for example obj["a"] vs obj.a to access the a field on obj.

So knowing this, you need to pass in 3 arguments to extract the values that you want to remove. For null and undefined I had to put them in separate variables, it wasn't working when putting them directly in the brackets:

I don't understand the rationale behind your question, but but perhaps this will help:
