I am looking for a bash command that will multiply only numbers from a text file. Below is the content of my text file. I need multiply all numbers by 100.
0 4530000 sil 4530000 11100000 ow 11100000 6320000 p 6320000 7600000 ah 7600000 8410000 n 8410000 12100000 sil
For single line with only number,I am using something like this below
for file in *.txt; do y=`sed -n '1 p' "$file"`; z=$(bc<<<"$y*100") sed $file -i -e 's/'"$y"'/'"$z"'/' done
But I dont know how to do it for multiple lines, with alphabets in them. Number of lines in my file are not fixed, each file has different number of lines with max being 8
Can use perl
perl -pe 's/b(d+.)?d+b/$&*100/ge' file
