Hi Folks,
I have a file with all fields defined by byte position, but any field can be empty so I cannot print lines based on a search of specific columns. I need to print all lines of this file where the string of two characters at byte position 100-101 contains the number 27. Any ideas?

Hi!
How can I print out a specific range of rows, like "cat file | awk NR==5,NR==9", but in the END-statement?
I have a small awk-script that finds specific rows in a file and saves the line number in an array, like this:
awk '
BEGIN { count=0}
/ZZZZ/ {
list=NR

dumpe2fs
DUMPE2FS(8) System Manager's Manual DUMPE2FS(8) NAME
dumpe2fs - dump ext2/ext3/ext4 filesystem information SYNOPSIS
dumpe2fs [ -bfghixV ] [ -o superblock=superblock ] [ -o blocksize=blocksize ] device DESCRIPTION
dumpe2fs prints the super block and blocks group information for the filesystem present on device. Note: When used with a mounted filesystem, the printed information may be old or inconsistent. OPTIONS
-b print the blocks which are reserved as bad in the filesystem. -o superblock=superblock use the block superblock when examining the filesystem. This option is not usually needed except by a filesystem wizard who is examining the remains of a very badly corrupted filesystem. -o blocksize=blocksize use blocks of blocksize bytes when examining the filesystem. This option is not usually needed except by a filesystem wizard who is examining the remains of a very badly corrupted filesystem. -f force dumpe2fs to display a filesystem even though it may have some filesystem feature flags which dumpe2fs may not understand (and which can cause some of dumpe2fs's display to be suspect). -g display the group descriptor information in a machine readable colon-separated value format. The fields displayed are the group number; the number of the first block in the group; the superblock location (or -1 if not present); the range of blocks used by the group descriptors (or -1 if not present); the block bitmap location; the inode bitmap location; and the range of blocks used by the inode table. -h only display the superblock information and not any of the block group descriptor detail information. -i display the filesystem data from an image file created by e2image, using device as the pathname to the image file. -x print the detailed group information block numbers in hexadecimal format -V print the version number of dumpe2fs and exit. BUGS
You need to know the physical filesystem structure to understand the output. AUTHOR
