Hammer & Screwdriver Here is one way

Code:

RXOCF-465 PDTR11 1

A2/EXT "BAP_BSC6/07B/00" 418 090529 1059

> grep "[A-Z0-9]" file22
A1/EXT "BAP_BSC6/07B/00" 844 090602 1605

And that command can redirect output to a new file, such as
Code:
grep "[A-Z0-9]" file22 > file22a

EBOOK-CONVERT(1)						      calibre							  EBOOK-CONVERT(1)

NAME
ebook-convert - part of calibre SYNOPSIS
ebook-convert input_file output_file [options] DESCRIPTION
Convert an ebook from one format to another. input_file is the input and output_file is the output. Both must be specified as the first two arguments to the command. The output ebook format is guessed from the file extension of output_file. output_file can also be of the special format .EXT where EXT is the output file extension. In this case, the name of the output file is derived the name of the input file. Note that the filenames must not start with a hyphen. Finally, if output_file has no extension, then it is treated as a directory and an "open ebook" (OEB) consisting of HTML files is written to that directory. These files are the files that would normally have been passed to the output plugin. After specifying the input and output file you can customize the conversion by specifying various options. The available options depend on the input and output file types. To get help on them specify the input and output file and then use the -h option. For full documentation of the conversion system see http://manual.calibre-ebook.com/conversion.html Whenever you pass arguments to ebook-convert that have spaces in them, enclose the arguments in quotation marks. OPTIONS
--version show program's version number and exit -h, --help show this help message and exit --list-recipes List builtin recipe names. You can create an ebook from a builtin recipe like this: ebook-convert "Recipe Name.recipe" output.epub SEE ALSO
