在 bash 中我有以下内容:
REGEX="(1.0.0|2.0.0)"
declare -a arr=("A:1.0.0" "B:1.0.0" "C:2.0.0" "D:2.0.1")
for i in "${arr[@]}"
do
echo "Found: $i"
if [[ "$i"=~"${REGEX}" ]]; then
echo "$i matches: ${REGEX}"
else
echo "$i DOES NOT match: ${REGEX}"
fi
done
我假设对于 D:2.0.1 它将打印 ...DOES NOT match... 但它会打印
Found: A:1.0.0
A:1.0.0 matches: (1.0.0|2.0.0)
Found: B:1.0.0
B:1.0.0 matches: (1.0.0|2.0.0)
Found: C:2.0.0
C:2.0.0 matches: (1.0.0|2.0.0)
Found: D:2.0.1
D:2.0.1 matches: (1.0.0|2.0.0)
那么我的 REGEX 组模式有什么问题？指定这样的组模式在其他语言中也能正常工作——例如像时髦的。
