sftp 返回码 [英] sftp return code

问题描述

我在网站上搜索了这个问题，但找不到解决方案.问题与 sftp 有关.我正在运行一个脚本，它接受 7 个参数，执行 SSH 并在 sftp 服务器上上传文件.我提供的参数是服务器，用户,port,source_directory,target_directory,source_file 和 tager_file.如果一切顺利，文件上传没有任何错误，返回码为 0.问题是如果任何参数错误，例如 target_directory，即使脚本返回 0 作为返回值.这是脚本的外观-

I seacrhed the site for this problem but could not find solution.Problem is related to sftp.I am running a script which accepets 7 parameters,does SSH and uploads the file on sftp server.Parameters i supply are-server,user,port,source_directory,target_directory,source_file and tager_file. if everything goes fine, file is uploaded without any error and return code is 0. Problem is if any parameter is wrong, like target_directory, even then script returns 0 as return value.Here is how script looks-

   typeset targetUsername=$1

typeset targetHostname=$2

typeset sftpPort=$3

typeset sourceDir=$4

typeset targetDir=$5

typeset sourceFilename=$6

typeset targetFilename=$7

typeset cmdPut="put ${sourceDir}/${sourceFilename} ${targetTempDir}/${tmpFileNam
e}"

typeset cmdRen="rename ${targetTempDir}/${tmpFileName} ${targetDir}/${targetFile
name}"

sftp ${sftpOption} ${targetUsername}@${targetHostname} <<EOF

${cmdPut}

${cmdRen}

bye
EOF

sftpStatus=$?

sftpStatus 应该返回状态.但我的状态总是为 0.任何想法，如何解决这个问题?非常感谢.

sftpStatus is supposed to return the status.But i am getting status as 0 always. Any idea, how to resove this? Thanks alot in advance.

推荐答案

你需要在批处理模式下运行 sftp，将你的命令放在一个文件中并将它传递给 sftp代码>.如果失败，您将获得退出代码 1，成功则获得 0.

You need to run sftp in batch mode, by putting your commands in a file and passing that to sftp. You will then get an exit code of 1 if there is a failure and 0 for success.

这是一些示例代码:

# create a temporary file containing sftp commands
BATCH_FILE="/tmp/$(basename $0).$$.tmp"
echo ${cmdPut} > ${BATCH_FILE}
echo ${cmdRen} >> ${BATCH_FILE}

# run sftp in batch mode
sftp -b ${BATCH_FILE} ${sftpOption} ${targetUsername}@${targetHostname} 
sftpStatus=$?

rm ${BATCH_FILE}
