How can we find out which one is tag and which one is branch?

[Pradeep Sharma]

In CVS, the branch and versions both, are shown as a string of numerals
separated by dot(.) so



How can we find out which one is tag and which one is branch without any
error or ambiguity using shell script?

Is there any script, command or way out?



Thanks and regards,

Pradeep,

You are getting into the internals of CVS and RCS which is unwise.
There are actually at least 3 different things: tags, branches and
vendor branches - and CVSNT also has alias tags and magic branches.

I'm not sure exactly what you're asking. If the question is, given a
version string, how can you tell whether it refers to a branch or a
revision, the general rule is that an odd number of components is a
branch and an even number of components is a revision. The exception is
that if there is an even number of components but the next to last
component is 0, then it's actually a (magic) branch. So:

1.2.3 - Branch
1.2.3.4 - Revision
1.2.0.1 - Branch (magic)

If that's not the question, you'll need to be more specific about what
you're looking for.
