@mitulpatel2003 sure you can do this. You'll need to use dscl to pull the info from the local machine and the jamf binary with the recon verb to do so. This is a rough, not tested, script you could use. Just one way to do it.
#!/bin/bash
loggedInUser=`/bin/ls -l /dev/console | /usr/bin/awk '{ print $3 }'`
firstName=`dscl . read /Users/${loggedInUser} FirstName | /usr/bin/awk '{ print $2 }'`
lastName=`dscl . read /Users/${loggedInUser} LastName | /usr/bin/awk '{ print $2 }'`
fullName="${firstName} ${lastName}"
shortName=`dscl . read /Users/${loggedInUser} RecordName | /usr/bin/awk '{ print $2 }'`
jamfCall="jamf recon -endUsername ${shortName} -realname '${fullName}'"
${jamfCall}
