Question

所以我试图在bash脚本中执行if else if else语句。截至目前，当我运行此脚本时，我收到以下错误消息“./groupJobs.sh:line 76：意外令牌附近的语法错误elif' ./groupJobs.sh: line 76: elif [$ jobsize -lt $ 2];然后'”

我已经在网上查看了多个示例，看不出我所做的和其他人说的有什么不同。

任何帮助将不胜感激。（第76行是最后一个elif声明）

if [ $filesize -ge $2 ]; then
#goes this way if file is to big to put in a job with anyother files
$filename >> $jobname$jobnumber;

elif [ $jobsize -ge $2 ]; then
#job is done being created

elif [ $jobsize -lt $2 ]; then
#add file to job and move on to next file check

fi

Answer 1

elif块的正文不能为空（评论不算）。如果您只需要固定身体，请使用:功能。

if [ $filesize -ge $2 ]; then
#goes this way if file is to big to put in a job with anyother files
$filename >> $jobname$jobnumber;

elif [ $jobsize -ge $2 ]; then
#job is done being created
:

elif [ $jobsize -lt $2 ]; then
#add file to job and move on to next file check
:

fi

Answer 2

elif语句需要一个实际的陈述。暂时将echo "job creation done"和echo "add file to job"放在那些陈述（或其他任何你想要的东西）中......

if [ $filesize -ge $2 ]; then
#goes this way if file is to big to put in a job with anyother files
$filename >> $jobname$jobnumber;

elif [ $jobsize -ge $2 ]; then
#job is done being created
echo "whatever you want"
#the above line just has to be some sort of actual statement

elif [ $jobsize -lt $2 ]; then
#add file to job and move on to next file check
echo "whatever you want"
#the above line just has to be some sort of actual statement
fi

Bash需要if / elif块中的命令（例如echo）。评论不计算在内。

Bash脚本如果elif elif不工作
