Can I view a specific chapter in a manual?  I tried man socket(2) in WSL Ubuntu 16.04 (Xenial).  This is after I got a recommendation to see chapter 2 in a man of the socket utility.

I wanted to access man pages for command chmod.  Command whatis chmod gave this output:  chmod (2)            - change permissions of a file  chmod (1)            - change file mode bits  But I was actually looking for chmod(2).  When I type man chmod, man pages for chmod(1) appears.   Both man chmod(2) and man 'chmod(2)' commands show error.   I tried running info coreutils 'chmod invocation', but output is some kind of documentation which doesn't look like a typical man page.

I'm working on a Power8 server running Ubuntu 16.04.2 LTS:  $ uname -a     Linux power 4.4.0-75-generic #96-Ubuntu SMP Thu Apr 20 09:55:30 UTC 2017 ppc64le ppc64le ppc64le GNU/Linux  $ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=16.04 DISTRIB_CODENAME=xenial DISTRIB_DESCRIPTION="Ubuntu 16.04.2 LTS"   None of the usual manpages appear to be installed. Even a simple command like:  man man   returns   No manual entry for man See 'man 7 undocumented' for help when manual pages are not available.   This goes for a variety of other tools, like ls, grep, etc. and library functions like usleep, printf, and so on.  I've checked that at least some manpages are actually installed:  $ dpkg -l | grep -i manpages ii  manpages                           4.04-2                                     all          Manual pages about using a GNU/Linux system ii  manpages-dev                       4.04-2                                     all          Manual pages about using GNU/Linux for development ii  manpages-posix                     2013a-1                                    all          Manual pages about using POSIX system ii  manpages-posix-dev                 2013a-1                                    all          Manual pages about using a POSIX system for development   Am I missing something? Is this specific to the ppc64le architecture? Or is there something else I can/should install to access these manpages?  Update: As requested, I ran sudo mandb. The result was:  0 man subdirectories contained newer manual pages. 0 manual pages were added. 0 stray cats were added. 2 old database entries were purged.   There were no changes to man man and other such commands.  Additionally, the output of manpath was:  $ manpath -g /usr/man:/usr/share/man:/usr/local/man:/usr/local/share/man:/usr/X11R6/man:/opt/man $ manpath -c /var/cache/man/oldlocal:/var/cache/man/local:/var/cache/man

says     On Linux, using devpts, there is no master device file. The process on the master end uses a file descriptor, which it gets by opening ptmx, but there’s no corresponding device node.   Did the author refer to /dev/ptmx or /dev/pts/ptmx?    Why are /dev/ptmx and /dev/pts/ptmx not device files? What types of files are they?  What is the difference between /dev/ptmx and /dev/pts/ptmx?  Thanks.

I often want to search through a man page, however I am forced to either do:  man &lt;package&gt; | grep &lt;search&gt;   Or:  man &lt;package&gt; &gt; file.txt   But there must be an easier way than this to do this, so how can I search through a man page while in it instead of having to send its contents to a file, or use grep to print the necessary matching contents to standard output?

If I know the index node (inode) of a file, but I don't know its path (or any of its paths), is it possible to create a hard link to that inode directly?  I could find the file using sudo find / -inum 123546 and then create a hardlink, but that would be way too slow for my application.  N.B. I'm using an ext4 filesystem.

I've been searching for a set of headers and connectors as defined in the  document for a casemod project.  Unfortunately, after scouring Digi-Key and a few manufacturer websites I can't seem to find any products actually advertised as suitable for this application.   Every other connector I've found so far is somewhat off in size and keying that I must be missing something in my search.   Is there such a thing as a USB 3.0 header or do I just need to keep comparing datasheets till I find something that makes sense?

I offered a friend to help translate from English some parts of his (mostly) Hebrew install. Then he told me two things:   1) That he's running 2.8 (he was worried about updating because he didn't want the design to break)   and 2) That he has reason to suspect that the site is infected with a trojan horse since it gets blocked by some antiviruses.  1) What is the best way to go about upgrading? is it even feasible to start on a fresh installation and still have everything intact? including redirects? or will I have to go about it as per WP's documentation: step by step upgrading.  2) What can be done about the trojan horse? this is why I'm contemplating a fresh install, which I know is probably not recommended.  Thank you in advance

What is the canonical way for accessing the local documentation on any available Shell Options builtin with shopt?  I'm using Ubuntu 12.04 and can run help shopt to get a description of what shopt does:  shopt: shopt [-pqsu] [-o] [optname ...]     Set and unset shell options.     ...   I can list the various Shell Options and their values (shopt or shopt -p). But how do I find out what each one actually does without leaving the comfort of my Linux box? I'm not looking for . Is there a man page or something I'm missing?

I have seen this question now many times and every question here and on other forum points to  experimental tutorial by . Now sadly a lot of answers are invalid right now because this central link is down. I couldn't find anything by Googling so if anybody has a fork of the tutorial or a second source that would be great? The link can't be gone for too long, I saw an answer with it 4 months ago.  The only other thing I have found is , but it also references the now missing tutorial. Any ideas how to find it?

In FreeBSD and also in Linux, how can I get the numerical chmod value of a file? For example, 644 instead of -rw-r--r--? I need an automatic way for a Bash script.

I've setup a connectio to an FTP server in Nautilus / Nemo / Caja, the file manager. Now I can browse the contents via this file manager.  How can I browse these files via the command line? What is the path to this network connection? Is this possible, is this a system connection, or specific to the file manager, and do I have to setup a separate FTP connection to do that? If I open this connection in Caja, I see it in Nemo as well, so it seems like a system connection.

The man command brings up a nice manual for many programs, but how can I use it more effectively? For example man gcc brings:  NAME        gcc - GNU project C and C++ compiler  SYNOPSIS        gcc [-c|-S|-E] [-std=standard]            [-g] [-pg] [-Olevel]            [-Wwarn...] [-Wpedantic]            [-Idir...] [-Ldir...]            [-Dmacro[=defn]...] [-Umacro]            [-foption...] [-mmachine-option...]            [-o outfile] [@file] infile...         Only the most useful options are listed here; see below for the        remainder.  g++ accepts mostly the same options as gcc. .... many text   But what if I need only some part of it? What is the best way to jump to the section where -Idir is described, for example?

Pages has crashed, my file is now corrupted and I'm trying to get the text from this file.  if I Right click on the file > Show package content > open index.zip , I can see a bunch of .iwa files which seems to contains my original text, especially "Document.iwa".  If I "$ nano Document.iwa" (because "$ file" only returns "data") I can see some of my text, but the overall seems crypted.  Does anyone know how to decode/read this kind of .iwa file or recover corrupted files?
