Hello all :)
I'm new to the mailing list.
I'm trying to convert the (simplified) code below to a case statement
structure:
===
if [[ $mycase -eq 0 ]]; then
echo "mycase is 0"
else
if [[ $mycase -eq 1 ]]; then
echo "mycase is 1"
else
echo "mycase is 2"
fi
echo "mycase is 1 or 2"
fi
===
And this is what I got:
===
case $mycase in
0)
echo "mycase is 0"
;;
1)
echo "mycase is 1"
;;
2)
echo "mycase is 2"
esac
if [[ $mycase -gt 0 ]] echo "mycase is 1 or 2"
===
My question is, shouldn't there be a way to do this:
===
case $mycase in
0)
echo "mycase is 0"
;;
1)
echo "mycase is 1"
;|
2)
echo "mycase is 2"
;|
*)
echo "mycase is 1 or 2"
esac
===
Note that ";|" provides an OR-like separator (as opposed to the AND-like
";&" separator) that goes through the case statements. However, unlike ";&",
it checks $mycase against 1) and 2) instead of blindly executing case
statements 1 & 2.
Wouldn't this be a good addition to ZSH? It certainly seems more useful than
";&".
