I am assigned a programming work.It is my first time to use unix.
The task is writing a shell script to interrogate the university Unix operating system to determine the number of "Runnable" processes at any given time.Then append the result,along with a time-stamp,on a log file. Also there are... (1 Reply)
Can somebody write a solution how to deal with negative unixdates in C/C++?
e.g. I should convert -222832800 into 12-10-1962.
I've read some texts about unixdate. They say that negative values are not officially supported, some functions use -1 to report a conversion error. How can I use this... (3 Replies)

Here is two time I have:
Jul 12 16:02:01
Jul 13 01:02:01
and how can I do a simple match to get difference between two time which is 09:00:00
Thanks in advance. (3 Replies)
I'd like to convert a date string in the form of sun aug 19 09:03:10 EDT 2012, to unixtime timestamp using awk.
I tried
This is how each line of the file looks like, different date and time in this format

I needed some help in adding a duration (in seconds) to a start time (in hhmmss format) and a start date (in mmddyy format) in order to get an end date and end time. The concept of a leap year is also to be considered while incrementing the day. The code/ function that I have formed so far is as... (3 Replies)
Hi guys thanks for the help for my previous posts.Now i have a requirement that i download a XMl file which has UTC time stamp.I need to convert UTC time into Unix server timezone.
For ex if the time zone of unix server is CDT then i need to convert into CDT.whatever may be the system time... (5 Replies)
Just finished a quick Python script to send the current unix time over to the Arduino from macOS, so in the absence of GPS or some other way to get the unix timestamp (epoch time) to the Arduino, I can get my macOS and Arduino UNO synced to within a second.
Normally, when the Arduino starts... (9 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.
