I want to test a program's memory management capabilities, for example (say, program name is director) What happens if some other processes take up too much memory, and there is too less memory for director to run? How does director behave? What happens if too many of the CPU cycles are used by some other program while director is runn...
I'm not sure why this code isn't working. Its not going to the copy command. I successfully run this manually on the command line (without the check) I don't think i'm performing a correct file check? Is there a better, cleaner way to write this? I just want to make sure the file exists, if so, copy it over. Thanks. #!/bin/bash if [ $...

Hi geeks, This maybe a linguistic question. I have checked the loop device on Wikipedia. It is just for mounting files as block device. But what does "loop" mean here? Its usage here is totally bizarre to me. I am not a native English speaker. So could someone explain this jargon to me in plain English? :) Thanks. ...
I have a unix script which creates a temporary log file, say tempfl.log. When this file is created it has permission rw-r--r--. There is a line chmod 0440 /etc/sudoers tempfl.log 2>&1 But when the script is done the permission changes to r--r--r-- but it should be rw-r--r--.

I want to use a library that uses file descriptors as the basic means to access its data. For performance reasons, I don't want to have to commit files to the disk each before I use this library's functions. I want to create (large) data blobs on the fly, and call into the library to send them to a server. As it stands, I have to write ...
I am looking for a way to determine file permissions for the current user (i.e. the process's UID) on POSIX-compliant systems. I don't want to try opening the file - that could get messy with directories and all kinds of special files. I am compiling a directory listing of a specified directory, and for each file, reporting a bunch of t...
