I am really struggling with a relatively simple regex (specifically with $ and ^)
Here is the thing: In regex101.com/r/cO8lqs/9955
Shouldn't all strings that end with 't' should get selected?
But none is selected here
And also In regex101.com/r/cO8lqs/9956 shouldn't all strings that start with 'c' should get selected but only one got selected?
What exactly is happening?

@daya $ is end of line, ^ is start of line
try \b for word boundry
although actually I guess php doesn't do multi-line by default, so ^ and $ are start and end of the entire string unless you use /m

Thanks, but why is that? I mean in many tutorials I have read ^ and $ are
for start and end of a *string* and not the entire line?

AndrolGenhald
the "string" is the entire input to the regex, including spaces and newlines

Oh I see
Here I wrote the regex considering the entire input as string
But still nothing matches..
Sorry, regex101.com/r/cO8lqs/9975 is correct link
here the entire input should be matched, right?

You've got ^ at the beginning, then c, but then there's nothing to match the a
did you want this: regex101.com/r/cO8lqs/9977?

Assuming a device is running with Secure Boot enabled and a modern M.2 PCIe SSD with a GPT partition table, is it possible to infect the SSD itself with malware? I'm thinking something like an MBR virus of the past, or infecting the SSD's firmware itself.
Also assume that the malware itself had unrestricted DMA via Thunderbolt 3.
