Question

我有一个问题，当作为cron作业执行时，将SCP消息重定向到文件：

(scp -q ${locationsFromTo[$i]} ${locationsFromTo[$i+1]}) >> $logFile 2>&1;

有没有办法将SCP错误重定向到文件？

这是脚本：

#!/bin/bash  
#The script scp the files from a remote server 
#The script will run only for ($sleepTime * $maxIterations) before exiting (default: 120 iteration, with sleep 5m = 10 hours)


    declare -a locationsFromTo=("test@ssh.server.com:IN/*" "/home/in/." "test@ssh.server.com:OUT/*" "/home/out/.");
    arraylength=${#locationsFromTo[@]};
    logFile="/home/scp.log";
    sleepTime=$((5 * 60));
    iterationCount=0;
    maxIterations=120;


echo "$(date) - Script is Started" > $logFile;

for (( i=0; i<${arraylength}; i+=2 ))
do
   while true
   do 
    echo "executing scp command" >> $logFile;
    (scp -q ${locationsFromTo[$i]} ${locationsFromTo[$i+1]}) >> $logFile 2>&1;
    if (($? == 0)); then 
        echo "$(date) - scp success" >> $logFile; break;
    else
        echo "scp command failed" >> $logFile;
        if(($iterationCount >= $maxIterations-1)); then 
            echo "$(date) - script is running too long. exiting." >> $logFile; 
            break;
        else
            iterationCount=$iterationCount+1;
            sleep $sleepTime
        fi;
    fi;
    done;
done;

Cron作业来自$ logFile：

Wed Mar 25 09:10:01 EDT 2015 - Script is Started
executing scp command
scp command failed

来自$ logFile的手动执行结果：

Wed Mar 25 13:25:58 EDT 2015 - Script is Started
executing scp command
scp: fromOUAC/*: No such file or directory
scp command failed

我刚删除'-q'标志以允许“scp”输出。（我还必须包含密钥文件的路径）

显然scp检测到它从终端运行时是什么时候将它的输出更改为无声。 https://serverfault.com/questions/187620/scp-report-progress-to-cron-output

现在我的SCP命令＆amp;脚本看起来像这样：

#!/bin/bash  
declare -a locationsFromTo=("test@ssh.server.com:inDir/*" "/home/user/inDir/." "test@ssh.server.com:outDir/*" "/home/user/outDir/.");
arraylength=${#locationsFromTo[@]};
logFile="/home/user/logDir/scp.log";
keyFile="/home/user/.ssh/keyFile";

for (( i=0; i<${arraylength}; i+=2 ))
do
   scp -i $keyFile ${locationsFromTo[$i]} ${locationsFromTo[$i+1]} >> $logFile 2>&1;

done;
