通过expect执行scp，传输文件不完整的解决方法

写了一个脚本来传输文件，类似于这样：

sendsystem(){
expect -c "
           spawn scp $ORACLE_BASE/oradata/$ORACLE_SID/system01.dbf [email protected]$S_IP:$ORACLE_BASE/oradata/standby/
           expect {
               yes/no { send \"yes\r\"; exp_continue }
               *assword* { send \"oracle\r\" }
           };
           expect 100%
           expect eof ;
       "
}

sendsysaux(){
expect -c "
           spawn scp $ORACLE_BASE/oradata/$ORACLE_SID/sysaux01.dbf [email protected]$S_IP:$ORACLE_BASE/oradata/standby/
           expect {
               yes/no { send \"yes\r\"; exp_continue }
               *assword* { send \"oracle\r\" }
           };
           expect 100%
           expect eof ;
       "
}

结果：

spawn scp /home/oracle/std_control01.ctl oracle@192.168.134.134:/oracle/oradata/standby/std_control01.ctl
oracle@192.168.134.134‘s password:

system01.dbf没传完就不传了

又试了几次发现偶尔其他文件也会传不完就不传了

最后发现是因为expect默认timeout为30S

手动添加set timeout -1设置超时时间为无穷大，问题解决

sendsystem(){
expect -c "
           set timeout -1
           spawn scp $ORACLE_BASE/oradata/$ORACLE_SID/system01.dbf [email protected]$S_IP:$ORACLE_BASE/oradata/standby/
           expect {
               yes/no { send \"yes\r\"; exp_continue }
               *assword* { send \"oracle\r\" }
           };
           expect 100%
           expect eof ;
       "
}
