问题描述
我试图运行的cygwin在Windows下面的bash脚本7
I am trying to run the below bash script in cygwin on windows 7
REPEATTIMES="$1"
if [ $# = 0 ]; then
echo "Usage: fetch topN repeatTimes"
exit 1
fi
for (( i=1; i<=$REPEATTIMES; i++ ))
do
echo "ITERATION: $i"
echo "GENERATING"
log=thelogs/log
bin/nutch generate crawl/segment -topN 10 > $log
batchId=`sed -n 's|.*batch id: \(.*\)|\1|p' < $log`
echo "batch id: $batchId "
# rename log file by appending the batch id
log2=$log$batchId
mv $log $log2
log=$log2
echo "FETCHING"
bin/nutch fetch crawl/segments/$batchId >> $log
echo "PARSING"
bin/nutch parse crawl/segments/$batchId >> $log
echo "UPDATING DB"
bin/nutch updatedb crawl/crawldb crawl/segments/$batchId >> $log
echo "Done "
done
但是，当我运行它，我得到的错误：
But when i run it i get the error :
line 11 :syntax error near unexpected token '$'\r'
line 11 :'for (( i=1; i<= REPEATTIMES; i++ ))
该脚本正常工作Ubuntu的服务器上。但我现在需要在Windows机器上运行它。
The script works fine on a ubuntu server. But i need to run it now on a windows machine.
推荐答案
Cygwin的最新版本似乎只支持Unix的格式的文件（即\\ n作为相对于DOS / Windows的新行\\ r \\ n换行）
The latest version of Cygwin seems to only support files in Unix format (i.e. with \n for newlines as opposed to the DOS/Windows \r\n newline).
要解决这个问题，运行/bin/dos2unix.exe实用工具，让您的脚本作为参数传递给命令：
To fix this, run the /bin/dos2unix.exe utility, giving your script as the argument to the command:
e.g. /bin/dos2unix.exe myScript.sh
这将其转换为Unix格式，然后你应该能够运行它。
This will convert it to Unix format and you then should be able to run it.
