那位高手能告诉我上面红色几句是什么意思！

是哪个版本哪个文件名?

是genesis8.02b版本的，文件名c:\tmp

alias cdgtt 'cd $GENESIS_TMP'
cdgtt
set get_id1 = `ps -e|grep get |awk '{print $1}'`
set tst1 = genesis1$$.$get_id1
set tst2 = genesis2$$.$get_id1
set copp = genesis2$$.$get_id1
sed s/ceot/set/g $tst > $tst2
cat $tst2 | sed s/@@@/=/g > $tst1
cat $tst1 | sed s/incom/if/g > $tst2
cat $tst2 | sed s/invof/then/g > $tst1
tail -128 $tst1 > $copp
source $copp; rm $copp; rm $tst1
sed -n 545p $copp > $tst1
sed -n 545p $tst1 > $copp
