shell script - multipal file

[shuai_wang]

I am a beginner in shell script. I have a question here.

I have more than 2000 files named:

vsd.000000
vsd.000001
vsd.000002
vsd.000003
...
vsd.001999

each of them have some data like:

[vsd.00000]
user0000
12 12 011 01
.....

I wan to make a shell scrpt to read all the files and write the first number to a new file.
What can I do?

Thanks.

You can use a for loop with gnu read..
