下面是我写的shell脚本：到if [ $path -eq $(date +%Y%m03) ]行就报错：
#! /bin/sh
path=$(date +%Y%m%d)
echo "path=$path $(date +%Y%m03)"
echo "$(date -d"1 month ago" +"%Y%m01")"
cd /home/smp/RECEIPT/
mkdir $path
yesterday=$(date -d"1 day ago" +"%Y%m%d")
month=$(date -d"1 month ago" +"%Y%m01")
ftp -n IP <<!
user 用户名 密码
bin
cd ftp服务器的路径
lcd 本机指定路径
prompt
if [ $path -eq $(date +%Y%m03) ]
then
echo("true")
mget *SMFWC_971_01DY_$yesterday* *SMPGD_971_01MO_$month* *SMPSR_971_01MO_$month*
else
echo("false")
mget *SMFWC_971_01DY_$yesterday*
fi
bye

脚本运行日志如下：
path= 20131103
20131001
mkdir: 缺少操作数
请尝试执行“mkdir --help”来获取更多信息。

求大神指点，为什么会?Invalid command.，应该怎么修改！急！在线等待！
问题出在echo("true") 或者echo("false")这一句，ftp里面不支持，你手动执行一下就知道了。
ftp> echo("true")?Invalid command

这块是有问题，删除后运行，还是会提示?Invalid command
追答你在ftp那段here doc里面，使用shell的语法都是不行的。
if [ $path -eq $(date +%Y%m03) ]
then
fi
这些都算?Invalid command的。
你这样改
#! /bin/shpath=$(date +%Y%m%d)
echo "path=$path $(date +%Y%m03)"
echo "$(date -d"1 month ago" +"%Y%m01")"
cd /home/smp/RECEIPT/
mkdir $path
yesterday=$(date -d"1 day ago" +"%Y%m%d")
month=$(date -d"1 month ago" +"%Y%m01")
if [ $path -eq $(date +%Y%m03) ]
then
ftp_cmd="mget *SMFWC_971_01DY_$yesterday* *SMPGD_971_01MO_$month* *SMPSR_971_01MO_$month*"
else
ftp_cmd="mget *SMFWC_971_01DY_$yesterday*"
fi

试过了不行，在说了日期$path 和 $(date +%Y%m03) 应该都不是string吧！
