Man page find flag

The find command recursively searches the directory tree for each specified Path parameter, seeking files that match a Boolean expression. The Boolean expression is written by using the terms that are provided in the following text. When the find command is recursively descending directory structures, it does not descend into directories that are symbolically linked into the current hierarchy. The output from the find command depends on the terms that are specified by the Expression parameter. The find command does not support the 4.

Master the command line: How to use man pages

Is there any tool that simplifies it? I could of course write a simple function in Bash grepping the contents of a man pages but I am looking for something that uses the structure of man pages to find exactly what I want i.

Assuming your man pager is less , you can pass any command to less beforehand using the environment variable LESS. You can change the pattern for finer control.

If you want to go to the specific option of the man page rather than searching, you can use Regex matching with LESS :. You can also define a function likewise:.

Anyhow, do you know how to add it to your. However, this simple function seems to do exactly what I need:. Sign up to join this community. The best answers are voted up and rise to the top.

What it does effectively is it searches for the flag in the man page.

I want it to take me to the flag immediately. See my answer, it looks like the best way to do this. I know, and your solution works well after this fix. Still I think the solution in my answer is cleaner. Note that none of this solution directly queries man database, which is what I really want.

There is one thing. It iptables -t nat -n -L Well, the last two lines are destroyed. Several different tables may be defined. Each table contains a number of built-in chains and may also contain user-defined chains. If the kernel is configured with automatic module loading, an attempt will be made to load the appropriate module for that table if it is not already there. The tables are as follows: -- This is the default table if no -t option is passed.

IPv6 NAT support is available since kernel 3. The exact output is affected by the other arguments given. The exact rules are suppressed until you use iptables -L -v -S, --list-rules [chain]. It would also match "delta-transfer" or "--omit-dir-times" from the rsync man page.

You also might want to use grep -A5 so that the results include a few lines of context. See update. It should be included in Release 1. I don't see much difference.

How to Search Man Pages at the Command Line

By using our site, you acknowledge that you have read and understand our Cookie Policy , Privacy Policy , and our Terms of Service. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I'm trying to come up with a way to find a specific flag in a man-page.

In Unix-like and some other operating systems , find is a command-line utility that locates files based on some user -specified criteria and then applies some requested action on each matched object. It initiates a search from a desired starting location and then recursively traversing the nodes directories of a hierarchical structure typically a tree. The possible search criteria include a pattern to match against the filename or a time range to match against the modification time or access time of the file.

Is it some kind of arcane knowledge, handed down only to initiates after grueling initiations? Well, no. Actually, anyone can learn about Terminal commands, if they know where to look. The key to Terminal wisdom is the man command.

Use the Unix find command to search for files

While they're not all well-advertised, there are actually a variety of means of getting help under Unix. Man pages correspond to online manuals for programs, file formats, functions, system calls, and so forth. If you've never read one before, the best way to start is by typing 'man man ' at the command line. Of course, while man pages are a vast improvement over the online documentation of most other OSes, they suffer from many failings: some people don't like to read text on the screen not very helpful unless you already know what to look for not always accessible even when present not always present, especially under Linux frequently hard to read, as they try to be authoritative and are therefore often too technical for new users frequently out of date That said, they're still better and more comprehensive than the alternatives. We'll try to address the first three failings in this document. Man pages are the standard documentation for every Unix; you're sure to come across a reference before too long of the form:. Where N is a number from , possibly followed by a letter.

find Command

Section-num : Since a manual is divided into multiple sections so this option is used to display only a specific section of a manual. So this option gives the section in which the given command is present. In this example you can move through the manual pages sections i.

Search a folder hierarchy for filename s that meet a desired criteria: Name, Size, File Type - see examples. GNU find searches the directory tree rooted at each given file name by evaluating the given expression from left to right, according to the rules of precedence see Operators , until the outcome is known the left hand side is false for AND operations, true for OR , at which point find moves on to the next file name.

find (Unix)

To use the find command, at the Unix prompt, enter:. Leave the double quotes in. The find command will begin looking in the starting directory you specify and proceed to search through all accessible subdirectories.

In the absence of an expression, -print is assumed. If an expression is given, but none of the primaries -delete , -exec , -execdir , -ls , -ok , -print , or -print0 are specified, the given expression is effectively replaced by given expression -print. It is not an error to specify more than one of the mutually exclusive options -H and -L. Where more than one of these options is specified, the last option given overrides the others. If terminated by a semicolon, the utility is executed once per path. This form of the primary evaluates to true if utility exits with a zero exit status.

On Linux and other Unix -like operating systems , man is the interface used to view the system's reference manuals. Each argument given to man is normally the name of a program , utility or function. The manual page associated with each of these arguments is then found and displayed. A section number, if provided, will direct man to look only in that section of the manual. The default action is to search in all of the available sections, following a pre-defined order and to show only the first page found, even if page exists in several sections.

Feb 1, - The flag -u causes this function to be marked undefined. The FPATH variable will be searched to find the function definition when the function is.

When typeset is invoked inside a function, a new instance of the variables name is created. The variables value and type are restored when the function completes. The following list of attributes may be specified:. Left justify and remove leading blanks from value. If n is non-zero it defines the width of the field; otherwise, it is determined by the width of the value of first assignment.

When reading a Unix manpage in the terminal, how can I jump easily to the description of a particular flag?

Command line users are undoubtedly familiar with man pages, or manual pages, that contain details, help , and documentation to specified commands and functions. Referencing a man page can be essential when trying to learn proper syntax or how a command works, but with how large some manual pages are it can be a real drag to scroll through the entire man page to try and find a relevant portion. Note the flag is a capital -K, the string can be anything. Any matches to the syntax in the current man page will be highlighted.

    I think, that you are mistaken. I can defend the position. Write to me in PM, we will discuss.
