Ok I'll do my best...
while [ $start -lt ${#lsarry[*]} ]
Simple while loop.
It keeps looping until the var $start is lessthan the total number of elements in the arry.
eg ${#lsarry[*]} would be equall to 4 if
the array is made up as follows "A B C D"
The # indicates to give the "count" of the elements in the arry and the "*" simply indicats ALL the elements.... (I guess its like a wild card...ie ls *-> which list every thing)
the "-d" is a test for a directory. Does it mean "IF 'D' = ArrayValue?" NO.
Do a man on "test" and you will see all the options. UNIX will "test" the input and return true if the path/to/target is a directory or false if not. How is it being inerpreted?
if [ -d ${lsarry[$start]} ] How is the code being interpreted? - as you know $start is increased by 1 each loop so the "next" element in the arry is placed into the "test" statment and evaluated....ie ${lsarry[1], ${lsarry[2], etc....
you can run the script with full debug on to see whats happening by either...
1) add set -x to the second line ....or
2) # sh -x {scriptname}
Hope this helps.
PS do a man on sh-bourne or man on ksh and near the bottom it talks about arrays and what "#" etc means....
Have fun :-)
