OK, so a quick background:

(1) I would like to know any unix/Linux command to check EOF char in a file.
(2) Or Any way I can check a file has been reached completely at machine B from machine A. Note that machine A ftp/scp the file to machine B at unknown time. (5 Replies)
I know how to check if any file has a unix process using a file by looking at 'lsof <fullpath/filename>' command.
I think using lsof is very expensive. Also to make it accurate we need to inlcude fullpath of the file.
Is there another command that can tell if a file has a truely active... (12 Replies)
For the selection of motherboards, is there any naming convention in the type numbers?

Hi,
I am installing a new RHEL 5 application server containing JBOSS along with other specific 3rd party applications. I know that this usually gets installed in /opt but I was thinking of installing these on a new separtate lv / file system instead.
i.e.

Hi
Currently we have nmon running on our Red hat Linux server.
The ouput file is now coming with the naming convention as "servername_160321_0010.nmon".
The output file naming convention has to be changed as "nmon_servername_daily_2016.03.21_00.00.00"
How can we do it ? Any suggestions... (10 Replies)

ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
