Hi, friends~
I'm reading the Bash Reference Manual, section 3.2.5.2.
Here: <https://gnu.org/s/bash/manual/html_node/Conditional-Constructs.html>.
case _word_ in
[ [(] _pattern_ [| _pattern_]…) _command-list_ ;;]…
esac
Each _pattern_ undergoes tilde expansion, parameter
expansion, command substitution, arithmetic expansion,
process substitution, and quote removal.
^^^^^^^^^^^^^^^^^^^^
I'm confused. Why is "process substitution" being performed here?
The result is often unforeseen, e.g., '/dev/fd/13', '/dev/fd/42'...
Can anyone give me a practical example? Thanks in advance!
