在 evenno 中使用双 n 并使用大括号确保变量结束的位置:

#!/bin/bash
eisinno="INE728J01019_arya1.pdf"
evenno=10576
efilename="remote_sag.pdf"

cd /home/rishabh/${evenno}
for file in *_${evenno}_*.pdf; do
   echo "Debug: ${file} ==> ${file/${evenno}_${eisinno}/${evenno}_remote_${efilename}}"
   # Alternative: 
   echo ${file} | sed "s/${evenno}_${eisinno}/${evenno}_remote_${efilename}/"

   mv -i "${file}" "${file/${evenno}_${eisinno}/${evenno}_remote_${efilename}}"
done
