Hi all,
in a script if I have: VERSION="3.2.0"
I can do: echo jj-$VERSION-jj and get jj-3.2.0-jj
however if I do: echo jj_$VERSION_jj I get jj_
How do I get the $VERSION to work with the underscores like the dashes do.
Thanks,
Jerry

You can use ${VERSION} to separate it.

I see 4 ways:
echo jj_${VERSION}_jj
echo jj_"$VERSION"_jj
echo jj-$VERSION-jj | tr '-' '_'
printf jj_%s_jj $VERSION
I am sure there are others.

Parenthesis didn't work for me... Braces and escape work. I gave the escape example, but I think the braces solution is the pedantically most proper. ******************************************************************* This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
