确认ftp成功上传文件

这段代码用于ftp上传文件,并确认是否成功。欢迎大家提出意见。
除了 "#/bin/sh", 其余#开头的行都可以移除。你也许不能直接拷贝这些代码，最好用vi将那些不可见的字符删掉。

#Here is the shell script how to ftp send 3 files.
#I like to send some files to remote file server in one batch and must make sure if this batch was ftp sucessful.
#These files looks like following: 2008-01-01 08:00:01.000, ctn 2008-01-01 08:00:01.txt, all 2008-01-01 08:00:01.txt
#Fistly, we must find the file *.000 in local server, if no this file, don't send this batch
#We suppose the local folder is /home/ers/out
#And the remote folder is /
#/bin/sh
ftpusername='guest1'
ftppassword='password123'
#backup the files which will sent
cp /home/samba/ers/out/*.* /home/samba/ers/bak
#In order to avoide the conflict, move the files to a temp folder named "buffer" firstly
mv /home/samba/ers/out/*.* /home/samba/ers/buffer
cd /home/samba/ers/buffer
#get the file *.000, it is a flg file. e.g 2008-01-01 08:00:01.000
ls -rt *.000 > /home/samba/ers/localfile.lst
sed -e "s/.000//g" /home/samba/ers/localfile.lst > /home/samba/ers/localfile.txt
localfile=`head -1 /home/samba/ers/localfile.txt`
ctrfile="ctr "$localfile".txt"
allfile="all "$localfile".txt"
markfile=$localfile".000"
#end of get file name which will be sent.
#put three files in one batch
ftpresults=`ftp -vn<<!
  open 220.1.1.2
  user $ftpusername $ftppassword
  binary
  prompt off
  cd /buffer
  lcd /home/samba/ers/buffer

  put "$allfile"
  put "$markfile"   
  lcd /home/samba/ers
!
`
#Analysis the ftp results, output the ftp results to a log file firstly.
echo $ftpresults > /home/ftp.log
#As the ftp result have no return, so split this log to some lines. use "tr", it is very impotant.
#Then get the key words "bytes sent in"
ftp_success=`echo $ftpresults|tr "." "\n"|grep "bytes sent in"|wc -l`
# Above sentance mean add a return if met ".", and find "bytes sent in", then count the words "bytes sent in"
echo $ftp_success
#If we got three times "bytes sent in", it means ftp three files sucessful.

直接执行ftp后用$?来判断不行吗?

whuang

没试过

hfvbc

$?就是用来判断命令是否执行成功的特殊标志.

whuang

不行的。$?得不到什么结果。也许你可以给个例子

hfvbc

ftp 命令      #execute ftp command
if [ $? -ne 0 ];then       #if ftp command does not execute successfully then print the error message
    echo "error message!"
    exit 1
fi
other command   #if ftp command execute successfully then do other thing next

不可能的。

$?只是返回ftp -n这个命令的返回值。
即使第一句open 220.1.1.2命令就出错了，$?仍然是0，因为ftp -n这个命令是执行成功了的。

whuang

可能是remote server有问题，或者其他原因，不管ftp成功与否，$?永远是0
谢谢你的代码，我会在研究一下。

hfvbc

那不也可以用$?来判断open 的吗?

open是ftp命令的子命令，是Here Doc的内容，是没有办法用$?来判断的。
