脚本运行日志如下:

mkdir: 缺少操作数
请尝试执行“mkdir --help”来获取更多信息。

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
ftp> help
Commands may be abbreviated. Commands are:
! debug mdir sendport site
$ dir mget put size
account disconnect mkdir pwd status
append exit mls quit struct
ascii form mode quote system
bell get modtime recv sunique
binary glob mput reget tenex
bye hash newer rstatus tick
case help nmap rhelp trace
cd idle nlist rename type
cdup image ntrans reset user
chmod lcd open restart umask
close ls prompt rmdir verbose
cr macdef passive runique ?
delete mdelete proxy send

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 $(date +%Y%m03) ]
then
fi
这些都算?Invalid command的。
你这样改
#! /bin/sh
path=$(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")
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
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
$ftp_cmd
