Code:

arr=(`ls $@`) --> {`ls $@`}
echo ${arr[*]}

hi posix,
I tried your method, and its showing me
execute permission denied.!
I have give 755 permission to all files in my directory...

If u just need to store the file names in another file then u can try this option.

Code:
$ cat run.sh
read name
ls $name >> file_name.txt

Make sure while entering the file pattern you put a *.
Example: err*
In this case file_name.txt will have all the files matching the patter.

i tried to check how many files got retrived for the below code. It displays as 1. but there are 3 files in the dir which matches to the pattern.

Code:
$ vi run.sh
arr={`ls $@`}
echo ${#arr[*]}

i got the o/p as below
Code:
$ . ./run.sh scr*
1

Please update me why the above script returns 1 as o/p instead of 3.
