Thanks Bakunin!!!
I realize now I hid the real problem...
My question originated because when I execute:
Code:
myexe > /tmp/config
. /tmp/config
in concurrent scripts, sometimes, the second line is executed when someone other is writing /tmp/config, ending in an error.
Perhaps the simpler idea is to change script in :
how to make a line BLINKING in output and also how to increase font size in output
suppose in run a.sh script
inside echo "hello world "
i want that this should blink in the output and also
the font size of hello world should be big ..
could you please help me out in this (3 Replies)
I'm new to PERL, but I want to take the page source and write it to a file or standard output. I used perl.org as a test website. Here is the script:
use strict;
use warnings;
use LWP::Simple;
getprint('http://www.perl.org') or die 'Unable to get page';
exit 0;

I have a list of DNS servers I need to look up information on. Each of these servers has a master and a slave database. Essentially what I need to do is create two text files for each server. One with the Master view and one with the Slave view. There's 20 servers, in the end I should have 40 text... (4 Replies)

ppmd
ppmd(1) utils ppmd(1)NAME
ppmd - file-to-file compressor
SYNTAX
ppmd [e|d] [switches] filename...|wildcard...
DESCRIPTION
It is written for embedding in user programs mainly and it is not intended for immediate use. I was interested in speed and performance
improvements of abstract PPM model [1-6] only, without tuning it to particular data types, therefore compressor works good enough for
texts, but it is not so good for nonhomogeneous files (executables) and for noisy analog data (sounds, pictures etc.). Program is very mem-
ory consuming, you can choose balance between execution speed and memory economy, on one hand, and compression performance, on another
hand, with the help of model order selection option (-o).
OPTIONS -d Delete file[s] after processing, default: disabled.
-s Silent mode.
-fName Set output file name to Name.
-mN Use N MB memory - [1,256], default: 10. The PPMII algorithm might need a lot of memory, especially when used on large files and/or
used with large model order. If ppmd needs more memory than you give it, the compression will be worse. The exact effect is depen-
dent on the -r option.
-oN Set model order to N - [2,16], default: 4. Bigger model orders almost surely results in better compression and surely more memory
and CPU usage.
-r{0,1,2}
Methods of restoration of model correctness at memory insufficiency:
'-r0 - restart model from scratch'. This method is not optimal for any type of data sources, but it works fast and efficient in
average, so it is the recommended method (default).
'-r1 - cut off model'. This method is optimal for quasistationary sources when the period of stationarity is much larger than
period between cutoffs. As a rule, it gives better results, but it is slower than other methods and it is unstable against fragmen-
tation of memory heap at high model orders and low memory.
'-r2 - freeze model'. This method is optimal for stationary sources (show me such source when You will find it ;-)). It is fast
and efficient for such sources.
EXAMPLES
To run this program the standard way type:
ppmd e /tmp/myfile
Alternatively you can run it as:
ppmd -e -o 16 /tmp/myfile
