远程ls输出未重定向到文件

Question

当我运行以下代码时，我发现了这个错误

  

bash：/var/out.txt：没有这样的文件或目录

CREATE TEMPORARY TABLE "Tablename_20171024_115736_814_1" 
AS SELECT "column1","column2","column3"
FROM "database"."schema"."table" WHERE FALSE

Answer 1

Expect / Tcl不了解重定向（>）char。试试这个：

spawn bash -c "ssh user@10.103.234.1 ls -t /var/backups/archives/ > /var/outp.log"

Answer 2

使用tee替换 spawn ssh user@10.103.234.1'ls -t / var / backups / archives / | tee -a /var/outp.log'
