I don't think you can use awk to process parts of files in a loop, at least not without additional measures. Try this suggestion to create several .tmp files that you can loop through afterwards:
You could even leave out the /Bye.../ line if there's not too many files open...
Need to delete a text block inside a file, that is marked with a start and an end pattern. Eg

I was reading a book on UNIX internals "The design of the UNIX Operating system." There are two memory structures that are confusing me:
1) Buffer cache
2) Inode cache
My questions are
1) Does a process get both buffer cache and Indoe cache allocated when it opens/creates a file?
2) if no,... (1 Reply)

E2TOOLS(7) Miscellaneous Information Manual E2TOOLS(7)NAME
e2tools - utilities to manipulate files in an ext2/ext3 filesystem
DESCRIPTION
E2tools is a simple set of GPL'ed utilities to read, write, and manipulate files in an ext2/ext3 filesystem. These utilities access a
filesystem directly using the ext2fs library. I wrote these tools in order to copy files into a linux filesystem on a machine that does not
have ext2 support. Of course, they can also be used on a linux machine to read/write to disk images or floppies without having to mount
them or have root access.
Supported functionality:
e2cp copy files
e2mv move files
e2rm remove files
e2mkdir
create directory
e2ln create hard links
e2ls list files/directories
e2tail output the last part of a file
In general, to specify a directory or file on an ext2 filesystem for the e2tools utilities, use the following form:
filesystem:directory_path
The filesystem can be an unmounted partition or a regular file that's been formatted to contain an ext2 filesystem. In general, if a com-
mand takes multiple file names on the command line, if the first one contains an ext2 file specification, the rest of the files are assumed
to be on the same filesystem until another one is explicitly stated:
/tmp/boot.img:/tmp/file1
/tmp/file2
/tmp/file3
/tmp/boot2.img:/tmp/file4
Files 1-3 are on /tmp/boot.img and the last file is on /tmp/boot2.img
SEE ALSO e2cp(1), e2ln(1), e2ls(1), e2mkdir(1), e2mv(1), e2rm(1), e2tail(1).
