i'm using SOX to generate a spectrogram from a wave file with the command :
is there a way to create a spectrogram using the same command but reading file timestamps instead of the namefile.wav , since name is changing every 4 hours? (it's saved with cron at /direxample/test-$(date -v +\%H\%M).wav
Can someone help me with a Unix or perl script to convert the unix timestamps to human readable format?
Any help will be highly appreciated... (3 Replies)

Hi Friends,
please advise on shell script to add two time stamps
for example :
a=12:32
b=12:00
c=a+b=00:32
please help me to find shell script to add to two time stamps, as i need to convert time from EST to GMT or SST to prepare status of jobs in unix and to specify estimated time to... (3 Replies)
Hi,
We have smb client running on two of the linux boxes and smb server on another linux system. During a backup operation which uses smb, read of a file was allowed while write to the same file was going on.Also simultaneous writes to the same file were allowed.Following are the settings in the...

Hi! Long time reader first time registered user and poster.
I've picked up some times and tricks and I'm at a dead end... I've parsed a log file for duplicates and printed only the two fields I need (duplicate entry and time stamp).
My question is, with this output, how would I script... (2 Replies)
Hi,
i have current timestamp, lets say "12:02:45" in an variable (var1) and another timestamp "08:30:00" fetched from table in another variable2 (var2).
How do i compare 2 timestamps in unix shell scripting.
if var 1 > var 2 then echo message.
Thanks in advance. (3 Replies)
Hello fellow Unix geeks,
I have been given a very urgent assignment in my office on writing a particular Shell script but I'm very much new to it.I would appreciate any help from you on solving this problem--which might seem very trivial to you.

Hi all!!,
I'm using Ksh and working on Linux.
I want to compare two timestamps, timestamp1 and timestamp2.
Until, timestamp1 is lesser than timestamp2, i want to do something, lets say print something.
The code i have written is:
a=`date +%H:%M:%S`
b=`date +%H:%M:%S -d" 1... (1 Reply)
I am having problems because some of my files have timestamps that are earlier that 1.1.1970, the Unix start of time convention.
So I would like to write a script that finds all files in home folder and subfolders with timestamps earlier than 1.1.1970 and converts them to 1.1.1980.

Bio::Graphics::Glyph::spectrogram(3pm) User Contributed Perl Documentation Bio::Graphics::Glyph::spectrogram(3pm)NAME
Bio::Graphics::Glyph::spectrogram - The "spectrogram" glyph
SYNOPSIS
See L<Bio::Graphics::Panel>, L<Bio::Graphics::Glyph>
and L<Bio::Graphics::Browser::Plugin::Spectrogram>
DESCRIPTION
This glyph is designed to draw DNA spectrograms for the Spectrogram plugin. It is not meant to be used as a standalone glyph and has few
public options. Most of the glyph's behavior is controlled via the spectrogram plugin.
The glyph expects unaggregated 1D spectrogram features, each of which is a vertical column, with one row for each integer frequency. The
number of frequencies is controlled by the window size and/or the Spectrogram plugin. The width of the feature corresponds to the size of
the overlap between adjacent windows. The values for each frequency are in four channels, one for each base. The color of each row
("spot") represents the dominant base(s) and the intensity represents the magnitude of the signal at that frequency
The entire 2D spectrogram is a series of unaggregated, unbumped 1D spectrogram features.
The spectrogram glyph assigns colors using the HSV color space, where an angular coordinate for hue is assigned to each base (G yellow
[60]; A blue [240]; C green [120]; T red[0/360]). The saturation value is fixed at the maximum of 100 and the brightness value is scaled
according to the magnitude for each frequency, ranging from black to the pure hue.
The hue is determined in one of two ways:
If the signal for one base is dominant (> 50% of total for the four channels) the angular coordinate for that base is used. The brightness
is calculated using the total signal from all four channels.
If no base has a dominant signal, the weighted average angular coordinate is calculated using the relative contribution from each channel.
The brightness is calculated from the total signal from all four channels.
The y-axis labels require at least 40 pixels of left-padding. They will be truncated if less than 40 of padding is specified in the
configuration file.
OPTIONS
The following standard options are accepted:
Option Description Default
------------------------
-height Height of glyph calculated
-bump Whether to bump features off
The following glyph-specific options are also used:
-win window size used to calculate calculated
the spectrogram values
