ksh 里 ， set +e 问题

shot

set +e
                        
scp -r ${user}@${server}:/path/data/$YY/$MM/$DD/$i/*.tar .
rcode=$?
echo $rcode

set -e
if [[ $rcode -eq 0 ]]
then
rtry=0



set +e 是什么意思？
然后又 set -e

谢谢！

set -e 如果返回值不为0则退出

Use set -e

Every script you write should include set -e at the top. This tells bash that it should exit the script if any statement returns a non-true return value. The benefit of using -e is that it prevents errors snowballing into serious issues when they could have been caught earlier. Again, for readability you may want to use set -o errexit.
