When I execute the following command:cd /some/path/hereat -t 201409301100ls -al<CTRL-D>at -lovI get the following output:========================myusername.1411755840.a   Mon Sep 30 11:00:00 CDT 2014========================cd /some/path/herels -alWhat is causing the cd /some/path/here command to appear?  I'm using KornShell in AIX 6.1.My .envfile contains:if [ -t 0 ]; then        case `who am i | awk '{print $1}'` in                'myusername')                        #set the prompt to include the date and time                        #set -o allexport                        unset _Y _M _D _h _m _s                        eval $(date +_Y=%Y;_M=%m;_D=%d;_h=%H;_m=%M;_s=%S)                        ((SECONDS = 3600*${_h#0}+60*${_m#0}+${_s#0}))                        typeset -Z2 _h _m _s                        _tsub=(_m=(SECONDS/60%60)) == (_h=(SECONDS/3600%24)) + (_s=(SECONDS%60))                        #_timehm='${_x[_tsub]}$_h:${_m}'                        #_timehms='${_x[_tsub]}$_h:$_m:${_s}'                        _timedhms=$_Y'/'$_M'/'$_D '${_x[_tsub]}$_h:$_m:${_s}'                        _hn=`hostname`                        typeset -u _hn                        _un=`whoami | awk '{print $1}'`                        typeset -u _un                        export PS1=$_timedhms'['$_un']'$_hn':${PWD#$HOME/} $ '                        #set +o allexport                ;;                *)                ;;        esacfi
What is making at in AIX add a cd /some/path/here prior to my explicit commands?
