by using
foreach i (*.txt)
grep -o 'Modules:[0-9]' $i
end
i got return like
Modules:2
Modules:1
Modules:10
Modules:0
Modules:7
...
I want to cut off "Modules:" and only keep the integer number, how should i
use sed based on this output?
grep ... | sed
or
sed ... $(grep...)
Thanks.

Can you just pipe | result to sed ?

grep -o 'Modules:[0-9]' $i | sed 's/Modules://g'
or
grep -o 'Modules:[0-9]' $i | awk -F ":" '{print $2}'
or
grep -o 'Modules:[0-9]' $i |sed 's/^.*://g'
