Question

我想从脚本中提取scp命令并解析scp命令中的变量。

示例脚本：

if [[ $# -ne 1 ]]; then
      echo "ERROR: USAGE $0  <RUN_DATE>"
      echo "abcd_efgh_rfp.sh 20171003"
      exit 1
fi

RUN_DATE=$1

SLC_FILE_PATH=/a/b/c/d/
DROP_FILE_PATH=/a/
DROPZONE_HOST="a@dz.pp.com"
#Variables
sleep_time="1m"
exit_flag=0

echo "Source directory: ${DROP_FILE_PATH}"
echo "Target directory: ${SLC_FILE_PATH}"

echo "Start File pull from  DropZone to SLC - date ${RUN_DATE}"

echo "sftp for the file started"



file_watcher () {
    drop_file_name=a_${RUN_DATE}.txt
    slc_file_name=/a/b/c/d_${RUN_DATE}.txt
    dropzone_host="a@dz.pp.com"
    while [[ ${exit_flag} -eq 0 ]]
    do
        echo "Transferring file ${drop_file_name} to SLC ${slc_file_name}"
        scp -i ~/.ssh/id_rsa_dz_batch_regulatory ${dropzone_host}:${drop_file_name} ${slc_file_name}
                ##scp ${dropzone_host}:${drop_file_name} ${slc_file_name}
        if [[ $? -eq 0 ]]; then
            echo "Transfer of file - ${drop_file_name} to SLC - ${slc_file_name} is successful "
            exit_flag=1
        else
            echo "Files aren't placed in path: ${drop_file_name}, sleeping ${sleep_time} for file to be generated"

            incremental_wait=`expr $incremental_wait + 1`
            if [[ $incremental_wait -eq 1 ]]; then
                echo "incremental_wait=1 Transfer of dropzone file - ${drop_file_name} to SLC - ${slc_file_name} is failed "
                echo "++++++++++++++++++++++ ABORTING ++++++++++++++++++++++" >> ${log_file_name} 2>&1
                exit 1
            fi
            sleep ${sleep_time}
        fi
    done
  }

#Copying  files from dropzone to slc host
exit_flag=0
file_watcher ${DROP_FILE_PATH} ${SLC_FILE_PATH} ${DROPZONE_HOST}

所需的输出：提取scp命令并解析变量：

scp -i ~/.ssh/id_rsa_dz_batch_regulatory \
    ${dropzone_host}:${drop_file_name} ${slc_file_name}

解析变量后：

scp -i ~/.ssh/id_rsa_dz_batch_regulatory \ 
    a@dz.pp.com:a_$1.txt /a/b/c/d_$1.txt

变量的递归迭代
