How to get a list of tags created in CVS repository?

Question

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?

Answer 1

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
