I'm trying to define a 2D array in a bash script (.sh file), but I'm running into syntax errors. Here's how I've defined the array:
array=(
(25 "test1")
(110 "test2")
(143 "test3")
(465 "test4")
(587 "test5")
(993 "test6")
)
I've tried variations of this but keep getting errors like:
file.sh: line 4: syntax error near unexpected token `('
file.sh: line 6: syntax error near unexpected token `('
Am I missing something obvious?

Yeah, Bash lacks native support for 2D arrays. If you really need multiple dimensions, check out alternatives in languages like Python or C. It's a lot simpler that way!
Bash doesn’t support 2D arrays right out of the box. You might want to consider using associative arrays if you need a similar functionality. They can emulate 2D arrays but come with their own quirks.
Instead of forcing this in Bash, you might want to explore some solutions shared on forums, like what’s outlined in this Stack Overflow post. It could save you from complications.
As other commenters mentioned, Bash doesn't handle multidimensional arrays natively. You could try simulating it, but be aware that it can get messy and lead to issues.
Definitely check the relevant chapter in the Bash Manual for more insight. Understanding how Bash handles arrays will help!
