I need to find two numbers from lines which look like this
>Chr14:453901-458800
I have a large quantity of those lines mixed with lines that doesn’t contain ":" so we can search for colon to find the line with numbers. Every line have different numbers.
I need to find both numbers after ":" which are separated by "-" then substract the first number from the second one and print result on the screen for each line
I’d like this to be done using awk
I managed to do something like this:
awk -e '$1 ~ /\:/ {print $0}' file.txt
but it’s nowhere near the end result
For this example i showed above my result would be:
4899
Because it is the result of 458800 - 453901 = 4899
I can’t figure it out on my own and would appreciate some help
>Solution :
With GNU awk. Use : and - as field separators:
awk -F '[:-]' '/:/{print $3-$2}' file
Output:
4899
