How would I go about truncating a binary file when a certain pattern is found? For instance, I want to truncate the file at the first occurrence of the pattern 0xFFFFFFFF. I think something like awk could do the trick... but I'm not exactly sure how. thanks

Does cygwin work line wine, providing a compatibility layer inside a foreign os?

I would like to share data between a VirtualBox OSE guest OS and the host. This location should be also writable by either of the two.

I know that root can do anything, but is there a way to at least alert root that they are about to delete a folder that perhaps shouldn't be deleted? We keep a work directory in our /tmp folder, and from time to time an administrator will come along and purge the /tmp folder with roughly sudo rm...

And then another user user2 logs in, switches to sruser the same way and starts a process of id Y. (Multiple users can log in and swithch to sruser simultaneously.) In t...

I've been trying to find out with the man page and some other sources if the exit status doesn't necessarily mean you achieved an address but I'm thinking I maybe didn't read it correctly. Does anyone know why dhclient would still exit with 0 if it doesn't think I'm connected to a network? RHEL 6...

I'm working with a system where we want to allow users to play around with the date and time if they want, and where reboots may happen arbitrarily. This is fine, except for one thing: if there's a large time jump backwards, the following error appears on reboot: Checking filesystems IMAGE2: Sup...

When developing a solution that requires a real-time operating system, what advantages would an operating system such an QNX or VxWorks have over Linux? Or to put it another way, since these operating system are designed specifically for real-time, embedded use - as opposed to Linux which is a...

I'd like to be able to tail the output of a server log file that has messages like: INFO SEVERE etc, and if its SEVERE, show the line in red, if its info, in green. What kind of alias can I setup for a tail command that would help me do this?

How can I remove all empty directories in a subtree? I used something like find . -type d -exec rmdir {} 2>/dev/null \; but I needs to be run multiple times in order to remove directories containing empty directories only. Moreover, it's quite slow, especially under cygwin.
