This is the bash root shell. I have tried to just echo an array, and it completes successfully but then still gives the same input as before. I am also not able to make the for loop work, see below. This is probably because I do not have much experience with arrays. But the basic echo array returns the /vol/root without any subdirectories. Maybe I am not making the loop for the iteration correctly.
Basic echo array:
this gives errors:
Errors:
+ declare -a 'array=( drwxr-xr-x root root 4096 May 25 2012 /vol/root/ )'
testing_1130: line 2: syntax error near unexpected token `(('
testing_1130: line 2: `for (( i = 0; i < ${#array[@]}; i++ ))'
Again, any help you gurus have is always appreciated.

Reason: Please wrap data and sripts with CodeTags
How do I evaluate the result of a command assigned to a variable??
Example:
var1=`cmd`
rc=$?
rc will be the result of the assignment rather than cmd since it executes after. How do I evaluate the result of the command itself?
