EINVAL fd was created via a call to timerfd_create(2) and the wrong size buffer was given to read(); see timerfd_create(2) for further information. Manual pages are a descriptive help system that sometimes contains procedural help ("How do I..?") and sometimes the reason the command itself was created (the goal of the program). Most commands have simple uses and you can easily understand how they function. There is usually help available from the commands themselves by executing the command with the "--help" option. this contact form
POSIX.1-2001 allows either error to be returned for this case, and does not require these constants to have the same value, so a portable application should check for both possibilities. I have provided a link to a specific example of man page syntax behind every definition. I have looked in the /bin directory and there are a few files in there that were modified recently and have a file size of 0.

The "..." means that you have one or more times you can use these options. Remove advertisements Sponsored Links TonyFullerMalv View Public Profile Visit TonyFullerMalv's homepage! If the current file offset is at or past the end of file, no bytes are read, and read() returns zero. Sometimes a pipe "|" is used to separate options that are exclusive from one or the other.
WHEN may be `never', `always', or `auto' -d, --directory list directory entries instead of contents -D, --dired generate output designed for Emacs' dired mode -f do not sort, enable -aU, disable Notes On NFS file systems, reading small amounts of data will only update the timestamp the first time, subsequent calls may not do so. In looking at the man page you typed, the ls command without [OPTIONS]... filename must be a fully-qualified pathname.
Remember, manual pages are not designed to be a help system, but they do provide descriptions of the commands themselves. Is fgets a shell command? Is fgets a shell command? A testament to simplicy and usability, tens of thousands of pages of documenation exist, viewable in a common file format, usable via command line, or easily printed with minimal effort.
EAGAIN or EWOULDBLOCK The file descriptor fd refers to a socket and has been marked nonblocking (O_NONBLOCK), and the read would block. What versions? Don't worry too much about it right now. Another weird thing is that having the same man page installed in another linux box, in the same location, is opened without any problem (typing man nfwatchdog from any location).

POSIX allows a read() that is interrupted after reading some data to return -1 (with errno set to EINTR) or to return the number of bytes already read. Linux provides you with many command line tools to manipulate files.

The time now is 11:20 PM. Can you do an ls on /usr/share/man? Section 1 traditionally contains pages for commands supplied with the operating system.
Try to reinstall gzip which can be dowloaded from the net and move it to /bin directory. Various different UNIX systems put the name of the particular unix system (such as SOLARIS, AIX, HPUX, BSD, SGI, etc.) in this position. It is recommended that the line to be written parameter be surrounded by quotes. But when I directly execute: man /usr/share/man/man1/nfwatchdog.1.gz , the file is opened without any error.
Melson Nothing is more terrible than Rio Grande MicroSolutions ignorance in action. Definitions: Man pages come from various sources and although most are similar, the man page formats aren't entirely consistent. Linux command line programs generally come with their own documentation too; manual pages or man pages for short. http://mediacount.net/error-reading/error-reading-file.html man, version 1.6d GNU bash, version 3.2.25(1) Thanks in advance for any idea you could have.
NOTES top The types size_t and ssize_t are, respectively, unsigned and signed integer data types specified by POSIX.1. Currently, only some file systems (among them: Btrfs, ext2, ext3, and ext4) have full support for returning the file type in d_type. Manual pages were generally written by the person(s) that wrote the program themselves - they are descriptive enough to be of assistance, but not intended to be full documentation. I have created a man page, named nfwatchdog.1.gz.
EFAULT buf is outside your accessible address space. The "FSF" indicates this was written by the Free Software Foundation, Inc. (FSF). Although it might be beyond your comfort level now, if you acquire the source code to programs you can frequently find similar information in the READMEs that accompany the programs. On error, it returns a positive error number (listed under ERRORS).
The pipe is also used to indicate options that equate to each other. On some systems, such as a dedicated server, you may not have a GUI installed at all. They are a reference that frequently explains how the command functions so that you can easily understand its use. OPTIONs are preceeded by hyphens, and you can either specify them individually if you leave a space inbetween ( ls -a -l /home) or altogether ( ls -al /home ) if
