Changing file content based on file header
Hi,

I have several text files each containing some data as shown below:

File1.txt
HTML Code:
>DataHeader
Data...
Data...
File2.txt
HTML Code:
>DataHeader
Data...
Data...
etc.
What I want is to change the 'DataHeader' based on the file name. So the output should look like:
File1.txt
HTML Code:
 >File1
 Data...
 Data...
File2.txt
HTML Code:
>File2
 Data...
 Data...
Is there any unix command or shortcut to do that?
Thanks.

Try:
Code:
awk '/^>/{$0=">"FILENAME;sub(/.txt/,x)}1' infile
