I have something like this in bash on Linux:

some_variable= ls *somepattern* | xargs cat | wc -c

And i would like to multiply that by some amount like:

another_variable = $(($some_variable * 10))

But i get an error

-bash: * 100: syntax error: operand expected (error token is "* 100")

Why is it not possible to not multiply some_variable with wc?
