/var/www我为and创建了一个备份脚本/usr/lib/cgi-bin。每次编辑或添加文件时，都应通过incron.
root@corkea:~# incrontab -l
/usr/lib/cgi-bin IN_ATTRIB,IN_CREATE,IN_DELETE,IN_CLOSE_WRITE,IN_NO_LOOP create_incremental_backup_of_http_documents_and_cgi.sh
/var/www/html IN_ATTRIB,IN_CREATE,IN_DELETE,IN_CLOSE_WRITE,IN_NO_LOOP create_incremental_backup_of_http_documents_and_cgi.sh
我在 shell 中测试了脚本，它工作正常，但是使用incron脚本时总是返回错误。
我通过 Mail 收到的错误消息..
Apr 27 22:57:49 corkea create_incremental_backup_of_http_documents_and_cgi.sh[15011]: cp: regulÀre Datei â/var/tmp/http-documents-and-cgi-of-corkea.gtarâ kann nicht angelegt werden: Die Datei existiert bereits
Apr 27 22:57:49 corkea create_incremental_backup_of_http_documents_and_cgi.sh[15011]: Beende Skript, aufgrund vorheriger Fehler.
翻译：
cp: cant create file /var/tmp/http-documents-and-cgi-of-corkea.gtar, because it exist already.
Stopping script because of previous error(s).
此错误仅在incron用于启动脚本时发生。
不知何故，脚本在以下if else命令中失败了......
if [ -d "${BackupDirectory}/${SubDir}" ]
then
cp -f "$FileIncremental" "$TmpDir"
else
mkdir -p "${BackupDirectory}/${SubDir}"
fi
我添加 && [ -e "$FileIncremental" ] 到if命令中，但它也没有帮助。
这是脚本...

我做错了什么，你能帮帮我吗？
