Rename file with certain conditions
Hi,

Trying to rename a file nexus-1234 to nexus-$randomnumber.

This is what I have so far...


Code:
number=$RANDOM$RANDOM$RANDOM$RANDOM;
let "number %= 10000000000000000";
LOGFILE=test.log

for filename in ./*
 do	

   if [ -f "$filename" ]   
       then
	    file="${filename#*/}";            
	    if [[ "$file" == nexus* ]]
	    then
              var="nexus-1234"
		new_var= "${var/[0-9]*//}$number";
              echo $new_var >> $LOGFILE
		mv ./$var ./$newvar             
  	    fi  
   fi   
 done;

When I run this, I am getting.....

Code:
Command '"./changeBatchID.sh"'
failed with return code 0 and error message
./changeBatchID.sh: line 14: nexus-/1515109127742028: No such file or directory
mv: `./nexus-1234' and `./nexus-1234' are the same file.

Any help is appreciated. Thanks!
