Question

I’m trying to extract directory location from location.txt and save it into an array, but it’s not looking good. When I execute the script,

i get this error

  ./test.sh: line 7: location.txt: No such file or directory bina@ajax $ ./test.sh
  ./test.sh: line 5: =/apps/IBM: No such file or directory
  ./test.sh: line 5: =/usr/home: No such file or directory
  ./test.sh: line 11: Unix_Array[0]: command not found

  ./test.sh: line 11: Unix_Array[1]: command not found

Here is my code

   #!/bin/sh

   counter=0
   while read -r line; do
       ${Unix_Array[${counter}]}=$line;
       let counter=counter+1;
   done < location.txt

   for ((i=0 ;counter > i; i++))
   do
       echo $(Unix_Array[$i])
   done 

and the text file
location.txt

   /apps/IBM
   /usr/home
   /var/login

Can some one tell me what I did wrong?
I may have made one stupid error that i don’t know…(I’m really new in UNIX)

Thanks in advance

Just remove your first ${} on ${Unix_Array[${counter}]}=$line; because you just want to assign to the array, not assign and retrieve its value, your fixed script would be like this:

#!/bin/sh

counter=0
while read -r line; do
   Unix_Array[${counter}]=$line;
   let counter=counter+1;
done < location.txt

for ((i=0 ;counter > i; i++))
do
     echo ${Unix_Array[$i]}
done
