Linux find command man page By Alvin Alexander. 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 prece- dence see section OPERATORSuntil the outcome is known the left hand side is false for and operations, true for orat which point find moves on to the next file name.
If you are using find in an environment where security is important for example if you are using it to seach directories that are writable by other usersyou should read the "Security Considerations" chapter of the findutils documentation, which is called Finding Files and comes with findutils.
That document also includes a lot more detail and discussion than this manual page, so you may find it a more useful source of information.
That argument and any follow- ing arguments are taken to be the expression describing what is to be searched for.
If no paths are given, the current directory is used. These options control the behaviour of find but are specified immedi- ately after the last path name. This is the default behaviour. When find examines or prints information a file, and the file is a symbolic link, the information used shall be taken from the properties of the symbolic link itself.
When find examines or prints information about files, the information used shall be taken from the prop- erties of the file to which the link points, not from the link itself unless it is a broken symbolic link or find is unable to examine the file to which the link points. Use of this option implies -noleaf.
If you later use the -P option, -noleaf will still be in effect. If -L is in effect and find discovers a symbolic link to a subdirectory during its search, the subdirec- tory pointed to by the symbolic link will be searched.
When the -L option is in effect, the -type predicate will always match against the type of the file that a symbolic link points to rather than the link itself unless the symbolic link is bro- ken. Using -L causes the -lname and -ilname predicates always to return false. When find examines or prints information about files, the information used shall be taken from the prop- erties of the symbolic link itself.
The only exception to this behaviour is when a file specified on the command line is a sym- bolic link, and the link can be resolved. For that situation, the information used is taken from whatever the link points to that is, the link is followed. The information about the link itself is used as a fallback if the file pointed to by the sym- bolic link cannot be examined.
If -H is in effect and one of the paths specified on the command line is a symbolic link to a directory, the contents of that directory will be examined though of course -maxdepth 0 would prevent this.
If more than one of -H, -L and -P is specified, each overrides the oth- ers; the last one appearing on the command line takes effect. Since it is the default, the -P option should be considered to be in effect unless either -H or -L is specified.
GNU find frequently stats files during the processing of the command line itself, before any searching has begun.
These options also affect how those arguments are processed. Specifically, there are a number of tests that compare files listed on the command line against a file we are currently considering. In each case, the file specified on the command line will have been examined and some of its properties will have been saved.
If the named file is in fact a symbolic link, and the -P option is in effect or if neither -H nor -L were specifiedthe information used for the comparison will be taken from the properties of the symbolic link.
Otherwise, it will be taken from the properties of the file the link points to. If find cannot follow the link for example because it has insufficient privileges or the link points to a nonexistent file the properties of the link itself will be used. When the -H or -L options are in effect, any symbolic links listed as the argument of -newer will be dereferenced, and the timestamp will be taken from the file to which the symbolic link points.
The same con- sideration applies to -anewer and -cnewer. The -follow option has a similar effect to -L, though it takes effect at the point where it appears that is, if -L is not used but -follow is, any symbolic links appearing after -follow on the command line will be dereferenced, and those before it will not.
If the expression contains no actions other than -prune, -print is per- formed on all files for which the expression is true. Except for -follow and -daystart, they always take effect, rather than being processed only when their place in the expression is reached. Therefore, for clarity, it is best to place them at the beginning of the expression.
This option only affects tests which appear later on the command line.
The -follow option affects only those tests which appear after it on the command line. Unless the -H or -L option has been specified, the position of the -follow option changes the behaviour of the -newer predicate; any files listed as the argument of -newer will be dereferenced if they are symbolic links.
The same consideration applies to -anewer and -cnewer. Similarly, the -type predicate will always match against the type of the file that a symbolic link points to rather than the link itself. Using -follow causes the -lname and -ilname predicates always to return false.Let data packets have a size (including all headers) of bytes and acknowledgment packets a size of bytes.

If this option is used together with the -b option, dumpcap will stop writing to the current capture file and switch to the next one if filesize is reached. One kilobyte is equal to bytes (as this is we get that these bytes should be 62h. this is called the sign-extension.
