Hi There, was wondering if there is any specific reason that we have used '"github.com/codeskyblue/go-sh"' package instead of the already provided "os/exec" package.

Hello @linonymous,

One reason behind using special library was to get session support - With "os/exec" – we have to control session (having env variables etc). With go-sh - it is easy to manage session, chain commands etc.

@gopinath-langote May be mentioning the exit code of command in message is more appropriate. wdyt?

Hello @akhilbojedla,

Yes, you are right. Adding exit code is a good idea.

Updated the AC accordingly
