I believe bipinijith was on the right track, but didn't quite follow through with what was requested. This uses a shell expansion that is not defined by the standards, but is available in recent versions of both ksh and bash:
Code:
for i in *-module-*
do      echo mv $i ${i/-module-/-module1_0-}
done

Remove the echo after verifying that the mv commands it will print do what you want to have done.

But you hardcoded version 1.0 in there. What if it's 2.3.4? Although the parameter expansion supports nested vars, like ${i/foo/${bar}}, you have to grab the version somehow.

Hi mirni,
Quoting from the original request: "So the module name "module" becomes "module1_0", the rest are identical." I just did what was requested.

Code:
sed 's/-\([0-9][0-9]*\).\([0-9][0-9]*\)-/\1_\2-\1.\2-/'

Try this if you want to use sed.

A little easier to read, assuming your sed supports -r option.
If your sed does not support -r option, you should switch to GNU sed.
Code:
sed -r 's/-([0-9]+).([0-9]+)-/\1_\2-\1.\2-/'
