Shell Programming and Scripting

Hi All,

I have a file which looks like this:

Code:

Name1;A01
Name2;A01.047
Name3;A01.047.025
Newname1;B01
NewName2;B01.056.32
NewName3;B04.09.43
NewNewName1;C01.03
NewNewName2;C01.034.44

As you can see, in the file there is some name and followed by the name is some identifier. These identifiers have same identification alphabet (A, B, C until Z) if they belong to the same type.

My task is to extract all the names which belong to the same alphabet and store them in separate files.

For example,
A.dat will look like this:

Code:

Name1;A01
Name2;A01.047
Name3;A01.047.025

B.dat will look like this:

Code:

Newname1;B01
NewName2;B01.056.32
NewName3;B04.09.43

and C.dat

Code:

NewNewName1;C01.03
NewNewName2;C01.034.44

I am using Linux with BASH shell.
