awk syntax errors with double star **

问题 I'm using Debian 6 and GNU sed, trying to get awk to convert the output of du from a long string of bytes to a more human readable number with suffixes like Mb and Kb. (I know you can use the -h option, but I want to do this manually with awk.) So far, my command looks like this (I put in the newlines to make it more readable): du /test.img | grep [0-9]* | awk "{ sum=$1 ; hum[1024**3]='Gb';hum[1024**2]='Mb'; hum[1024]='Kb'; for (x=1024**3; x>=1024; x/=1024){ if (sum>=x) { printf '%.2f %s\n'
