This started with be exploring "regular expressions".
I discovered some tutorials that were using Bash in their samples.
One {lost the reference at the moment} was almost a match for a real
world problem I have.
But I've not used Bash in eons and have forgotten how to read a file
into a single variable or a array variable.
I've downloaded "Bash Reference Manual"
[https://www.gnu.org/savannah-checkouts/gnu/bash/manual/bash.html]
for when I need fine grained details.
I've bookmarked the various links on
[https://mywiki.wooledge.org/BashFAQ]
for quick reference.
I find neither to be search friendly.
Suggestions?
TIA
