Hello,
So I wanted to write a very simple script to remove some information from a text file and save it as something else.
For example I have a text file (let's call it txt) with three rows of numbers:
0 0 1 9 8 7 5 0 6 7 9
0 0 7 9 8 1 1 6 4 0 6
0 0 9 8 4 6 0 9 2 8 1

Hi,
I wrote a small script whose function is to execute the postemsg provided if the threshold breaches.
I want to log this postemsg messages to a log file. But I am not able to do. Can someone throw some light on how to log the output of this. I am pasting a snippet of that code.

I have Cygwin/X installed on Windows 7. In an xterm, I turned on logging via Main Options > Log to File.
When I open my log file with Vim I get a warning that it might be binary. Looking through the file I see what I think are VT datastream escape characters. It makes it hard to use the... (1 Reply)
Hi Everybody! First post! Totally noobie.
I'm using the terminal to read a poorly formatted book.
The text file contains, in the middle of paragraphs, hyphenation to split words that are supposed to be on multiple pages. It looks ve -- ry much like this.
I was hoping to use grep -v " -- "... (5 Replies)

bzz
BZZ(1) DjVuLibre-3.5 BZZ(1)NAME
bzz - DjVu general purpose compression utility.
SYNOPSIS
Encoding:
bzz -e[blocksize] inputfile outputfile
Decoding:
bzz -d inputfile outputfile
DESCRIPTION
The first form of the command line (option -e) compresses the data from file inputfile and writes the compressed data into outputfile. The
second form of the command line (option -d) decompressed file inputfile and writes the output to outputfile.
OPTIONS -d Decoding mode.
-e[blocksize]
Encoding mode. The optional argument blocksize specifies the size of the input file blocks processed by the Burrows-Wheeler trans-
form expressed in kilobytes. The default block sizes is 2048 KB. The maximal block size is 4096 KB. Specifying a larger block
size usually produces higher compression ratios and increases the memory requirements of both the encoder and decoder. It is use-
less to specify a block size that is larger than the input file.
ALGORITHMS
The Burrows-Wheeler transform is performed using a combination of the Karp-Miller-Rosenberg and the Bentley-Sedgewick algorithms. This is
comparable to (Sadakane, DCC 98) with a slightly more flexible ranking scheme. Symbols are then ordered according to a running estimate of
their occurrence frequencies. The symbol ranks are then coded using a simple fixed tree and the ZP binary adaptive coder (Bottou, DCC 98).
The Burrows-Wheeler transform is also used in the well known compressor bzip2. The originality of bzz is the use of the ZP adaptive coder.
The adaptation noise can cost up to 5 percent in file size, but this penalty is usually offset by the benefits of adaptation.
PERFORMANCE
The following table shows comparative results (in bits per character) on the Canterbury Corpus ( http://corpus.canterbury.ac.nz ). The very
good bzz performance on the spreadsheet file excl puts the weighted average ahead of much more sophisticated compressors such as fsmx.

Note that DjVu contributors have several entries in this table. Program compress was written some time ago by Joe Orost. Program ppmd is
an improvement of the PPM-C method invented by Paul Howard.
