Hi There,
I've written a script that processes a data file on our system. Basically the script reads a post code from a list file, looks in the data file for the first occurrence (using grep) and reads the line number. It then tails the data file, with the line number just read, and outputs to a... (3 Replies)
I'm trying to find a command which will allow me to remove a range of lines (2-4) from a .dat file from the command line without opening the file.
Someone mentioned using the ex command?
Does anyone have any ideas?
thanks (6 Replies)

Hi,
I have a linux server that was hacked and I have a bunch of files that sporadically contain the following lines through out the file:

I did't put the exact lines of the file in this post. The "Xxxx" are random letters/numbers.... (8 Replies)
GM,
I have an issue at work, which requires a simple solution. But, after multiple attempts, I have not been able to hit on the code needed.
I am assuming that sed, awk or even perl could do what I need.
I have an application that adds extra blank page feeds, for multiple reports, when... (7 Replies)

diffstat
DIFFSTAT(1) General Commands Manual DIFFSTAT(1)NAME
diffstat - make histogram from diff-output
USAGE
diffstat [options] [file-specifications]
SYNOPSIS
This program reads the output of diff and displays a histogram of the insertions, deletions, and modifications per-file.
DESCRIPTION
Diffstat is a program that is useful for reviewing large, complex patch files. It reads from one or more input files which contain output
from diff, producing a histogram of the total lines changed for each file referenced. If the input filename ends with .bz2, .Z or .gz,
diffstat will read the uncompressed data via a pipe.
Diffstat recognizes the most popular types of output from diff:
unified
preferred by the patch utility.
context
best for readability, but not very compact.
default
not good for much, but simple to generate.
Diffstat detects the lines that are output by diff to tell which files are compared, and then counts the markers in the first column that
denote the type of change (insertion, deletion or modification). These are shown in the histogram as "+", "-" and "!" characters.
If no filename is given on the command line, diffstat reads the differences from the standard input.
OPTIONS -c prefix each line of output with "#", making it a comment-line for shell scripts.
-f format
specify 0 for concise, 1 for normal output.
-k suppress the merging of filenames in the report.
-n number
specify the minimum width used for filenames. If you don't specify this, diffstat uses the length of the longest filename, after
stripping common prefixes.
-p number
override the logic that strips common pathnames, simulating the patch "-p" option.
-u suppress the sorting of filenames in the report.
-V prints the current version number
-w number
specify the maximum width of the histogram. The plot will never be shorter than 10 columns, just in case the filenames get too
large.
ENVIRONMENT
Diffstat runs in a portable UNIX(R) environment.
FILES
Diffstat is a single binary module, which uses no auxiliary files.
BUGS
Diffstat makes a lot of assumptions about the format of a diff file.
There's no easy way to determine the degree of overlap between the "before" and "after" displays of modified lines.
