Tomcat UNIX aliases

To make managing development instances of tomcat a little easier I have a few bash aliases (you can add these lines to your ~/.bash_profile):

alias tchome='export CATALINA_HOME=`pwd`; echo CATALINA_HOME=$CATALINA_HOME'
alias tctail='tail -f ${CATALINA_HOME}/logs/catalina.out'
alias tcless='less ${CATALINA_HOME}/logs/catalina.out'
alias tcshow='echo ${CATALINA_HOME}'
alias tc='${CATALINA_HOME}/bin/catalina.sh'

so my typical workflow is cd {tomcat-directory}, tchome and then I move back around the filesystem and use tc start and tctail.
