如何使 python 程序在 bash 脚本中循环执行？

Question

I have a bash script where to execute the python program within a loop as below. I see only once its getting executed with the below script. The echo statement prints all the filenames in the directory within the loop, whereas the pgm1.py executes only once. Kindly advice what i have to do it here to continuously getting executed for all the files with the directory. Here is the below code.

LOG_DIR="directorypathname"
DT_H=`date '+%Y-%m-%d_%H_%M_%S'`
linkage_path="directoryname" 
yourfilenames=`ls $linkage_path`

for eachfile in $yourfilenames
do
    python3.5 ${CODE_DIR}/pgm1.py ${linkage_path}/${eachfile}  &> ${LOG_DIR}/${DT_H}.log
    echo ${linkage_path}/${eachfile}
done

Answer 1

You got the syntax wrong

for eachfile in $yourfilenames ; do
   python3.5 ${CODE_DIR}/pgm1.py ${linkage_path}/${eachfile} &>> \
      ${LOG_DIR}/${DT_H}.log
   echo ${linkage_path}/${eachfile}
   done

That should do the trick
