Multiply first column by variable depending on unit

  • 772

I have du -sh output saved to txt file:

2.1G    /home/x/sample/2GB/
101M    /home/x/sample/100MB/
...

What I want is to multiply each value in the first column by a value taken from variable depending on the unit. So if for instance unit is G then multiply by $G and append the the result at the end of each line. How to do this in Bash?

bash awk sed

  1. It sounds like you're trying to get the bytes, so instead of using -h (which is a shortcut for --human-readable), just don't use it.

    du -s will get you the summarized byte count.
