How to select only those file names whose name contains only numerals.
Hi Guru's,

Before writing to this forum I have searched extensively on this forum about my problem.

I have to write a shell script which takes out only those file names from the given directory which contains only numbers. For example, In the given directory these files are present:

11059813.xls
59813.xls
059813.xls
813.xls
Names_0767957.xls
Summary.xls

So out of the above file names, the script output should select only the files whose name consists of numbers i.e.

11059813.xls
59813.xls
059813.xls
813.xls

I am a novice in this area. Please help me out all Guru's, as this is urgent for me.

Thanks.

if your shell is posix-sh compatible (ksh, bash, ...), then

filename generation rule:
+([0-9]).xls

echo +([0-9]).xls
ls +([0-9]).xls
for f in +([0-9]).xls
...

Running the following in your directory:
Code:
ls | grep [[:digit:]]

Will list only those files that have a number in the name.
