sftp return code
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 para开发者_Go百科meters,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 is supposed to return the status.But i am getting status as 0 always. Any idea, how to resove this? Thanks alot in advance.
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.
Here is some sample code:
# 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}
