关于猛砸，直到重复 [英] Bash about repeat until

问题描述

我想知道的语法是否正确。我不能测试它现在很抱歉，但对我很重要。它的一个FTP脚本。该文件名为 A.TXT ，我想创建一个脚本，将上传文件，直到成功为止。它将作品或没有？任何人都可以帮助我建立正确的PLS

  LOGFILE = /家庭/ transfer_logs / $ a.log
DIR = /家庭/发
搜索=`LS /家庭/ send`
FIRSTLINE =`egrep的连接$ LOGFILE`
secondline =`egrep的文件传输成功$ LOGFILE`如果[-z$搜索];然后
CD $ DIR
FTP -p -v -i 192.163.3.3＆LT; ../../example.script＆GT; ../../$LOGFILE 2  - ;＆放大器; 1
科幻如果
egrep的未连接$ LOGFILE;然后
重复
FTP -p -v -i 192.163.3.3＆LT; ../../example.script＆GT; ../../$LOGFILE 2  - ;＆放大器; 1
直到
[[-n $ FIRSTLINE＆放大器;＆安培; $ secondline]];
DONE
科幻
 

example.script包括：

 二进制
 MPUT A.TXT
 放弃
 

解决方案

确实 FTP 不会返回一个合理的结果？这将是最容易写：

 一会儿！ FTP ...;做睡1; DONE
 

如果你坚持要搜索的日志文件，这样做：

 时：;做
    FTP ...＆GT; $ LOGFILE
    grep的-qf文件传输成功$ LOGFILE和放大器;＆安培;打破
DONE
 

或者

 一会儿！测试-e $ LOGFILE || grep的-qf未连接$ LOGFILE;做
    FTP ...＆GT; $ LOGFILE
DONE
 

I want to know about that syntax is correct or not. I cant test it right now sorry, but its important for me. Its an FTP script. The file name is a.txt, I would like to create a script that will upload a file until it is successful. It will works or not? Anyone can help me to build the correct one pls

LOGFILE=/home/transfer_logs/$a.log
DIR=/home/send
Search=`ls /home/send`
firstline=`egrep "Connected" $LOGFILE`
secondline=`egrep "File successfully transferred" $LOGFILE`

if [ -z "$Search" ]; then
cd $DIR
ftp -p -v -i 192.163.3.3 < ../../example.script > ../../$LOGFILE 2>&1
fi

if
egrep "Not connected" $LOGFILE; then
repeat
ftp -p -v -i 192.163.3.3 < ../../example.script > ../../$LOGFILE 2>&1
until
[[ -n $firstline && $secondline ]]; 
done
fi

example.script contains:

 binary
 mput a.txt
 quit 

解决方案

Does ftp not return a reasonable result? It would be easiest to write:

while ! ftp ...; do sleep 1; done

If you insist on searching the log file, do something like:

while :; do
    ftp ... > $LOGFILE
    grep -qF "File successfully transferred" $LOGFILE && break
done

Or

while ! test -e $LOGFILE || grep -qF "Not connected" $LOGFILE; do
    ftp ... > $LOGFILE
done
