Man pages for find

Site Logo

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. And for those who use Terminal app, remember you can also search and launch manual pages from the Terminal Help menu directly, which would then allow you to use the aforementioned string search to look within a help doc to get further details.

Linux find command

Site Logo

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. If terminated by a plus sign, the pathnames for which the primary is evaluated are aggregated into sets, and utility will be invoked once per set, similar to xargs 1.

This form of the primary always evaluates to true. If any invocation exits with a non-zero exit status, then find will eventually do so as well, but this does not cause find to exit early. Exceptions are the primaries mindepth and maxdepth. The primaries may be combined using the following operators.

The operators are listed in order of decreasing precedence. Operators, primaries, and arguments to primaries must be separate arguments to find , i. The options [ -dfhXx ], primaries -amin , -anewer , -cmin , -cnewer , -delete , -empty , -execdir , -flags , -follow , -fstype , -iname , -inum , -ls , -maxdepth , -mindepth , -mmin , and -print0 , and operators -and , -not , and -or , are extensions to that specification.

Historically, the -d , -L , and -x options were implemented using the primaries -depth , -follow , and -xdev. These primaries always evaluated to true.

As they were really global variables that took effect before the traversal began, some legal expressions could have unexpected results. As -print always evaluates to true, the standard order of evaluation implies that -depth would never be evaluated. This is not the case. This version replaces it no matter where in the utility name or arguments it appears. The special characters used by find are also special characters to many shell programs.

As file names may contain whitespace and shell metacharacters, passing the output of find to other programs requires some care:. Use the -print0 or -exec primaries instead. The options are as follows: -d Causes find to visit directories in post-order i.

By default, find visits directories in pre-order i. File hierarchies may be specified without the -f option if they are given immediately after any other options. If the referenced file does not exist, the file information and type will be for the link itself. File information of all symbolic links not on the command line is that of the link itself. This option exists for backwards compatibility. If a file name contains any of the delimiting characters used by xargs, a diagnostic message is displayed on standard error, and the file is skipped.

Consider using -print0 instead. Always returns true. This executes from the current working directory as find recurses down the tree. Depth-first traversal processing is implied by this option. The -delete primary will fail to delete a directory if it is not empty. Following symlinks is incompatible with this option. The same as specifying the -d option. Optional arguments may be passed to the utility.

If the flags are not preceded by a dash, this primary evaluates to true if the flags specified exactly match those of the file. The same as specifying the -L option. These do not describe actual file system types; the former matches any file system physically mounted on the system where find is being executed whereas the latter matches any file system which is mounted read-only.

If gname is numeric and there is no such group name, then gname is treated as a group ID. The following information for the current file is written to standard output: its inode number, size in byte blocks, file permissions, number of hard links, owner, group, size in bytes, last modification time, and pathname. If the file is a block or character special file, the major and minor numbers will be displayed instead of the size in bytes. If the mode is symbolic, a starting value of zero is assumed and the mode sets or clears permissions without regard to the process's file mode creation mask.

If the mode is not preceded by a dash, this primary evaluates to true if the bits in the mode exactly match the file's mode bits. Note, the first character of a symbolic mode may not be a dash.

It prints the pathname of the current file to standard output, followed by a null character, suitable for use with the -0 option to xargs 1. It causes find to not descend into the current file. Note, the -prune primary has no effect if the -d option was specified.

Possible file types are as follows: b block special c character special d directory f regular file l symbolic link p FIFO s socket.

GUI Methods

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. The -H, -L and -P options control the treatment of symbolic links. That argument and any following arguments are taken to be the expression describing what is to be searched for. If no paths are given, the current directory is used.

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.

man command in Linux with Examples

In Unix , most programs, and many protocols, functions, and file formats, have accompanying manuals. With the man command, you can retrieve the information in the manual and display it as text output on your screen. To use the man command, at the Unix prompt, enter:. Replace topic with the name of the manual item about which you want more information. For example, to find out more about the FTP command, at the Unix prompt, enter:.

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.

How to Search Man Pages at the Command Line

On Unix-like operating systems, the find command searches for files and directories in a file system. Within each directory tree specified by the given path s, it evaluates the given expression from left to right, according to the rules of precedence see " Operators ", below until the outcome is known. At that point find moves on to the next path until all path s have been searched.

The find utility recursively descends the directory hierarchy for each path seeking files that match a Boolean expression written in the primaries specified below. Causes the file information and file type evaluated for each symbolic link encountered on the command line to be those of the file referenced by the link, and not the link itself. If the referenced file does not exist, the file information and type is for the link itself. File information for all symbolic links not on the command line is that of the link itself. Causes the file information and file type evaluated for each symbolic link to be those of the file referenced by the link, and not the link itself.
