Are there any CLI commands that can be used to get a list of Tags that have been created on a branch or head of a module within a specified time frame?

    If you have the history function enabled, you can execute the following command:

    cvs history -a -T
    

    It will give you some lines like this, giving you date+time, user, module and tagname of each tagging operation:

    T 2011-04-02 07:55 +0000 ralph  mylib [testtag:A]
    

    For more information check the cvsbook on history

    One can list tags or branches present in a module using the following command. This is something picked up from another answer at SO

    To list all tags:

    cvs -Q -d :pserver:*User*:*Pass*@*HostName*:/cvsroot rlog -h *Module*| awk -F"[.:]" '/^\t/&&$(NF-1)!=0{print $1}' | sort -u
    

    To List all branches:

    cvs -Q -d :pserver:*User*:*Pass*@*HostName*:/cvsroot rlog -h *Module*| awk -F"[.:]" '/^\t/&&$(NF-1)==0{print $1}' | sort -u
    

    This uses the magic branch numbers to identify is a symbolic link is a branch or a tag.

    As skaffman mentioned in one of the answers on this page, it is not possible to determine date when tag is created. The best one can do is to identify an approximate date by considering the most recent date listed in the logs for that tag.

    Something like this:

    cvs -Q -d :pserver:*User*:*Pass*@*HostName*:/cvsroot rlog -N -S -r*TagName* *Module* | grep ^date: | sort | tail -1 | cut -d\; -f1 | sed -e 's/date: //'
    

    This is a bash script I worked out to give list of all tags with their approx. creation date

    #!/bin/bash
    
    CVSROOT=$1
    PROTOCOL=$2
    LOGIN=$3
    PASSWORD=$4
    MODULE=$5
    REVISION=$6
    OUTPUT=$7
    
    CVS_HOST=""
    if test "${PASSWORD:-t}" != "t" ; then
        CVS_HOST=":${PROTOCOL}:${LOGIN}:${PASSWORD}@${CVSROOT}"
    else
        CVS_HOST=":${PROTOCOL}:${LOGIN}@${CVSROOT}"
    fi
    
    CVS_REVISION=""
    if test "${REVISION:-t}" != "t" ; then
        CVS_REVISION="-r${REVISION}"
    fi
    
    echo "\"Tag Name\",\"Create Date\"" > ${OUTPUT}
    
    echo "EXEC: cvs -Q -d ${CVS_HOST} rlog -h -S ${CVS_REVISION} ${MODULE} | awk -F"[.:]" '/^\t/&&\$(NF-1)!=0{print \$1}' | sort -u"
    cvs -Q -d ${CVS_HOST} rlog -h ${CVS_REVISION} ${MODULE} | awk -F"[.:]" '/^\t/&&\$(NF-1)!=0{print $1}' | sort -u | while read tagName
    do
        #get approx create date
        echo "EXEC: cvs -Q -d ${CVS_HOST} rlog -N -S -r$tagName ${MODULE} | grep ^date: | sort | tail -1 | cut -d\; -f1 | sed -e 's/date: //'"
        date=`cvs -Q -d ${CVS_HOST} rlog -N -S -r$tagName ${MODULE} | grep ^date: | sort | tail -1 | cut -d\; -f1 | sed -e 's/date: //'`
    
        #Save to output file
        echo "\"$tagName\",\"$date\"" >> ${OUTPUT}
    done

    I just learned:

    cvs status -v
    

    Lists all tags and braches for each and any file together with the revision it belongs to.

    You could work from there ...

    I am Using Cvs Repository using cvsnt(install) ..

    Queries:

    1) I want only List of tag name from cvs.

    2) How to create Repository using cvsnt.

    3) How to Check-in Entire module into New Repository.

    I try Sample:

    1) when I try to create a new repository

    cvs -d :pserver:<user>@<host>:<new_repository> init
    

    2) Import Module into repository

    cvs -d repository_path import name_of_project vendor_tag release_tag

    CVS can't do that, it's too primitive. Tags are attached to individual file revisions, not to the module or repository. Furthermore, the tags have no date metadata, so you can't tell when they were created, either.

    So none of the selection criteria you specified can be used. The only criteria you can use is a specific versioned file, which will tell you which revisions have which tags, but that's it.
