Extracting the numbers only from string using sed

I have this string Time: 4 days (361440 seconds) and trying to extract only the number 361440 from this. I have gotten so far as to extract 361440 seconds using sed "s/.*(\(.*\))/\1/" I keep going round in circles trying to just get the number from it.

Thanks

You didn't explain the rule of extraction very clearly. Just based on your sed codes, this grep line should work for your example:

grep -oP '\(\K\d+'

Ok, then extend your sed one-liner a bit:

sed 's/.*(\([0-9]\+\).*/\1/'
