Question

这个问题已经有答案了:

Syntax error: operand expected when using Bash (2 个回答)

Why equal to operator does not work if it is not surrounded by space? (4 个回答)

已关闭 5 年前。

我的脚本在 Bash 中抛出错误:

/tmp/hudson6482258714933636361.sh: line 7: ((: i <=  : syntax error:operand expected (error token is "<=  ")
cp: cannot stat 

‘/var/jenkins_home/jobs/Latha/jobs/ShirePoc/jobs/RetrieveJob/workspace/Deploy/retrieveUnpackaged/*’: No such file or directory

这是脚本:

COUNT= $(ls -1 | wc -l)
echo $COUNT
for (( i=1 ; i <= $COUNT ; i++ ));
do
  var=package$i.xml
  echo "FILENAME is $var"
  mv -f $var package.xml
  mkdir ${WORKSPACE}/Deploy/unpackaged
  cp -R ${WORKSPACE}/tools/Package/package.xml ${WORKSPACE}/Deploy/unpackaged/
  cd ${WORKSPACE}/Deploy/unpackaged 
  cat package.xml
  ls -ltra
  cd ${WORKSPACE}/Deploy/
  ls -ltr
  ant -buildfile build.xml RetrieveComponent
done

为什么脚本会导致错误？

我相信罪魁祸首是你的 COUNT 变量，将其更改为如下:

COUNT=$(ls -1 | wc -l)

似乎 = 和 $ 之间有空格。请检查并告诉我们进展如何。
