This question already has an answer here:
Why does my regular expression work in X but not in Y?
1 answer
I have Bash script below, trying to capture last digits of 'pingnet' but can not get a match. I verified in regex101 and my regex is correct:
pingnet="pingcount,site=DC,cur=200 total-up=988"
regex='(d+)$'
if [[ $pingnet =~ $regex ]]
then
echo "YES"
echo "$BASH_REMATCH[1]"
else
echo "NOT"
echo "$BASH_REMATCH[1]"
fi
The result of running script is NOT.

Bash's regex syntax does not recognize d; use [[:digit:]] instead:
pingnet="pingcount,site=DC,cur=200 total-up=988"
regex='([[:digit:]]+)$'
