Does Solaris impose limits on :
- the maximum number of files a directory can have,
- total file size in a directory
If there is such limits, how can I can check for each?
Thanks...:confused: (1 Reply)
I need to write a Unix shell script which will list top 10 files in a directory tree on basis of size. i.e. first file should be the biggest in the whole directory and all its sub directories.
Please suggest any ideas (10 Replies)
Hi,
I had a directory and many subdirectories and files with in it.
Now i want to get the timestamp of files from the files and folders recursively. :(
Please help me to generate a script fort he above mentioned requirement!
Appreciate for ur qick response

Hi All,
I have this command coded in C Shell to get the top ten sub directories in the order of number of files they contain.
find $parent_dir -type d -exec filecount {} \; | sort -nr | head -10
But it does not seem to show any output. Can someone please help me out in correcting this... (5 Replies)
Hi
I have a requirement like below
I need to sort the files based on the timestamp in the file name and run them in sorted order and then archive all the files which are one day old to temp directory

I need to be able to identify files with file timestamps greater than a given timestamp.
I am using the following solution, although it appears to compare files at the "seconds" granularity and I need it at the milliseconds. When I tested my solution, it missed files that had timestamps... (3 Replies)
I've the files in a directory in the following format having date +%Y%m%d%H
YR_MNTH_2013061205
YR_MNTH_2013060107

Hi,
I'm using Kali linux, I think it's a debian linux ?
I'm trying to create a folder in which there'll be 256 folders, and in each of this folders there will also be 256 folders.
Then in each terminate folders I want to create 4096 files.
It will look like /dir/aa/aa/aaa.txt,... (3 Replies)

SYNOPSIS
numm-run FILE
DESCRIPTION
Frequency makes for a meaningful description of many audio signals. We can use numpy's fourier analysis to compute spectra from the micro-
phone and display the results visually. We will break down the process into smaller parts: baby steps...
First, create and save a skeletal file that moves a line across the screen:
idx = 0
def video_out(a):
global idx
a[:,idx] = 255
idx = (idx + 1) % a.shape[1]
def audio_in(a):
pass
Save this snippet and run it with numm-run.
We will use the numpy.fft module for our analysis. First we define a function to get a particular frequency from the fourier transform:
import numpy as np
def get_freq(fourier, frequency):
freqs = np.fft.fftfreq(len(fourier), 1/44100.0)
nearest = (abs(freqs - frequency)).argmin()
return abs(fourier[nearest])
Next, we hook up this function to audio input from the microphone. A frequency bin is chosen on a log scale for each row on the screen to
display a spectogram. In total:
import numpy as np
idx = 0
recent_audio = np.zeros(4096, np.int16)
recent_video = np.zeros((240,320,3), np.uint8)
freq_bins = np.exp2(np.linspace(np.log2(27000),np.log2(27),240))
def get_freq(fourier, frequency):
freqs = np.fft.fftfreq(len(fourier), 1/44100.0)
nearest = (abs(freqs - frequency)).argmin()
return abs(fourier[nearest])
def video_out(a):
global idx
fourier=np.fft.fft(recent_audio)
values =np.array([get_freq(fourier,X) for X in freq_bins])
recent_video[:,idx,1] = (values/10000).clip(0,255)
idx = (idx + 1) % a.shape[1]
a[:] = np.roll(recent_video, -idx, axis=1)
def audio_in(a):
recent_audio[:] = np.roll(recent_audio, len(a))
recent_audio[:len(a)] = a.mean(axis=1)
