Hi friends,
I want your help.
I have a flat file. I want a script to search following pattern in it and once it get that pattern it should grep next 7 characters from it and should keep it in output file output.TXT

Pattern is
RSTD3R0*******

In above example, characters in the place of * (7 characters after pattern RSTD3R0) should be grepped and sent to output.TXT file.

How it can be done?
Kindly help

Regards
