My fault, I should have been more verbose. The var=(..) creates an array variable; whereas the var=$(..) construct runs a sub-shell and stores the output as a string (the last one is equivalent to var=`..`). So with my example you can get your list back by using the array. $ echo ${filelist[@]} Putting files in an array also lets you loop over them easily. for file in ${filelist[@]}; do some_cmd; done (or in oneline: for file in ${filelist[@]}; do some_cmd; done) As you can see to access the whole array, I use the [@] index. You can also use [*] there. There is a subtle difference between the two when in side double quotes, otherwise they are equivalent. You can read all about it in the bash info page under array (info "(bash) Arrays"). To access individual files in the array you can use: ${filelist[1]} That said, I do not think storing the files in a variable is necessary at all. This is how I would do it. for file in $log_year-$log_month-$log_day--*.zip; do some_cmd; done Simple and easy! Hope this helps, -- Suvayu Open source is the future.
