可以构建一个数组来保存每个文件的所有附件选项，如下所示：

#!/usr/bin/env bash

# Produces no result if no match for pattern
shopt -s nullglob

# Captures recipients from script arguments
recipients=("$@")

# Populates aray with xls file paths
xls_files=(./*.xls)

# If there are xls files
if [ "${#xls_files[@]}" -gt 0 ]; then

  # Declare an array to store mailx attachment options
  attach_option=()

  # Creates an attachment option for each file to be attached
  for file in "${xls_files[@]}"; do
    attach_option+=(-a "$file")
  done

  # Sends mail with all the attachment options
  mailx -s "Testing File Conv" "${attach_option[@]}" "${recipients[@]}"
fi

您必须为此编写一个脚本。首先创建test.txt。

ls *.xls -1 > test.txt

然后运行以下脚本：

while read line
do
mailx -s "Subject" -a ${line} -s "files" ${mail_from} << EOM

Hi, Sent files

EOM

done<test.txt
