I have myMethod that gives me available,used,free disk space in KB. I parse the used disk space using awk. That gives me something like 830,016. I want the output to be 830016 so that I can add 100000 to it. In other words I would like to use used_space variable in numeric calculations (using expr).
Code:
.....
myMethod
used_space="`myMethod | grep sum | awk -F' ' '{print $3}'`"
echo $used_space
echo ${used_space/,/}
But the last line above gives me error:
Code:
sum 1,977,920 830,016 1,147,904
830,016
./test.sh: bad substitution
What can I do? If I do the same thing on command line it works fine!
Code:
bash-3.00# export abc=830,123
bash-3.00# echo ${abc/,/}
830123
bash-3.00#
