Man find mtime minutes

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.

Daddy, I found it!, 15 Awesome Linux Find Command Examples (Part2)

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. For example, -amin 2 is true if the file is accessed within 1 to 2 minutes. Files that are accessed after the find command start time is not taken into account. However, when the find command is used within the unary NOT operator for non- UNIX03 behavior, the files that are modified after the command start time are displayed until the value of n.

Files with i-nodes modified after the find command start time is not taken into account. However, when the find command is used within the unary NOT operator for non- UNIX03 behavior, files with i-nodes modified after the command start time is displayed until the value of n. If the file is a special file, the size field contains the major and minor device numbers.

Formatting is similar to that of the ls -filds command, however formatting is done internally without running the ls command.

Therefore, differences in output with the ls command might exist, such as with the protection mode. Files that are modified after the find command start time are not taken into account.

However, when the find command is used within the unary NOT operator for non- UNIX03 behavior, the files modified after the command start time are displayed until the value of n. In an expression such as [a-z], the hyphen means through according to the current collating sequence. A collating sequence might define equivalence classes for use in character ranges.

Example: To list a file, which is a part of the TCB environment, find -perm -print. It lists the names of the files that have only owner-read and owner-write permission and are a part of the TCB environment.

See the chmod command for an explanation of permission codes. Initially, a template is assumed with all file mode bits cleared. Op - symbols have the following function:. The op symbol - cannot be the first character of mode. It avoids ambiguity with the optional leading hyphen. Because the initial mode is all bits off, there are no symbolic modes that must use - as the first character.

If the hyphen is omitted, the primary evaluates as True when the file permission bits exactly match the value of the resulting template. Otherwise, if mode is prefixed by a hyphen, the primary evaluates as True if at least all bits in the resulting template are set in the file permission bits. The Mode parameter is identical to the chmod command syntax.

This expression evaluates to the value True if the file has exactly these permissions. If the optional - hyphen is present, this expression evaluates to the value True if at least these permissions are set. These expressions can be combined by using the following operators in the order of decreasing precedence:. Purpose Finds files with a matching expression. Syntax find [ -H -L ] Path Flags Item Description -H Causes the file information and file type that are evaluated for each symbolic link that is encountered on the command line to be those of the file that is referenced by the link, and not the link itself.

If the referenced file does not exist, the file information and type are for the link itself. File information for all symbolic links not on the command line is that of the link itself. These Boolean expressions and variables describe the search boundaries of the find command as defined in the Path and Expression parameters.

Note: Files that are accessed after the find command start time are not taken into account. The previous behavior of -atime evaluated as True if the file was accessed in n -1 to n multiples of 24 hours. By default, find -atime works like it did before UNIX Note: Files with i-nodes that are modified after the find command start time are not taken into account. However, when the find command is used within the unary NOT operator for non- UNIX03 behavior, files with i-nodes modified after the command start time are displayed until the value of n.

The previous behavior of -ctime evaluated as True if the file was accessed in n -1 to n multiples of 24 hours. By default, find -ctime works like it did before UNIX Note: Files that are modified after the find command start time are not taken into account.

The previous behavior of -mtime evaluated as True if the file is modified in n -1 to n multiples of 24 hours. By default, find -mtime works like it did before UNIX Note: For files that are a part of TCB environment, additional security bits are added to the permission of the files.

Therefore, the octal permissions value of a TCB enabled file must include the bit setting of along with its other permission bits. Note: If the -regextype option is not used, the regular expressions are interpreted as basic. Note: When you use the find and cpio commands together, you must use the -follow option and the -L option with the cpio command.

Not using these two options together produces undesirable results. If expression is not present, -print as used in the default expression. The -user , -group , and -newer primaries each evaluate their respective arguments only once.

Using a command that is specified by -exec or -ok does not affect subsequent primaries on the same file. Item Description 0 All Path parameters were traversed successfully.

Note: Every directory has at least two links: the entry in its parent directory and its own. The ln command explains multiple file links. It is the correct entry if you want the command to act on files that are not accessed for more than a week seven hour periods.

The rm command is the only parameter that is specified for the -exec expression. Note: Because the -H flag is used, time data is collected not from dirlink but instead from dir1 , which is found by traversing the symbolic link. Causes the file information and file type that are evaluated for each symbolic link that is encountered on the command line to be those of the file that is referenced by the link, and not the link itself.

Causes the file information and file type that are evaluated for each symbolic link to be those of the file that is referenced by the link, and not the link itself. Evaluates to the value True if the expression in parentheses is true. The value of n can be one of the following values: n Evaluates as True if the file access time subtracted from the initialization time, divided by 60 seconds with any remainder discarded , is n.

The value of n can be one of the following values: n Evaluates as True if the file access time subtracted from the initialization time, divided by seconds with any remainder discarded , is n. The value of n can be one of the following values: n Evaluates as True if the file i-node modification time subtracted from the initialization time, divided by 60 seconds with any remainder discarded , is n. Writes the current file to the specified device in the cpio command format.

The value of n can be one of the following values: n Evaluates as True if the file i-node modification time subtracted from the initialization time, divided by seconds with any remainder discarded , is n.

Always evaluates to the value True. Causes the descent of the directory hierarchy to be done so that all entries in a directory are affected before the directory itself is affected. It can be useful when the find command is used with the cpio command to transfer files that are contained in directories without write permission.

Evaluates to the value True if the specified command runs and returns a 0 value as exit status. The end of the specified command must be punctuated by a semicolon in quotation marks, an escaped semicolon, or a plus sign. Evaluates to the value True if the file system to which the file belongs is of the specified type.

The Type variable has a value of jfs journaled file system , nfs network file system , jfs2 enhanced journaled file system , procfs proc file system , or namefs name file system.

Evaluates to the value True if the file belongs to the specified group. Evaluates to the value True if file has an i-node matching the value of the n variable. Evaluates to the value True if the file has the specified number of links. See the ln command for a description of links.

Evaluates to the value True if the entire path name of the file matches the regular expression. This option is similar to the -regex option, except that the match is case-insensitive. Causes the current path name to be printed together with its associated statistics.

These statistics include the following values: I-node number Size in KB bytes Protection mode Number of hard links User Group Size in bytes Modification time If the file is a special file, the size field contains the major and minor device numbers. The value of n can be one of the following values: n Evaluates as True if the file modification time subtracted from the initialization time, divided by 60 seconds with any remainder discarded , is n.

The value of n can be one of the following values: n Evaluates as True if the file modification time subtracted from the initialization time, divided by seconds with any remainder discarded , is n.

Evaluates to the value True if the value of the File variable matches the file name. The typical shell file name generation characters see the sh command can be used. The pattern must be enclosed in either quotation marks or the escape characters. The escape character is used when the find command is used from the shell.

You can use wildcard pattern-matching characters, provided they are in quotation marks. Evaluates to the value True if the current file is modified more recently than the file indicated by the File variable. The same as the -exec expression, except that the find command verifies whether it must start the specified command.

An affirmative response starts the command. Evaluates to the value True if the permission code of the file exactly matches the OctalNumber parameter. For details about file permissions, refer to the chmod command. If the optional - hyphen is present, this expression evaluates to the value true if at least these permissions are set.

The OctalNumber parameter can be up to 9 octal digits. The mode argument is used to represent file mode bits.

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.

I can't find anything in the find man page to do this, only to compare against another files time or to check for differences between created time and now. Is making a file with the desired time and comparing against that the only way to do this? The reference argument is normally the name of a file and one of its timestamps is used for the comparison but it may also be a string describing an absolute time. X and Y are placeholders for other letters, and these letters select which time belonging to how reference is used for the comparison. Sign up to join this community.

A Guide to the Linux “Find” Command

The find command allows users to search for files and take actions on them. It is highly flexible, allowing you to look for files and directories based on a variety of conditions. Optionally, it also allows you to take different types of actions on the results.

Find command can do lot more than just searching for files based on name. In this article Part 2 , let us discuss 15 advanced examples of find command including — finding files based on the time it is accessed, modified or changed, finding files comparatively, performing operation on found files etc. She was very happy to spot the sea lion in the California Long Beach Aquarium. In the following examples, the difference between the min option and the time option is the argument. To find the files based up on the content modification time, the option -mmin, and -mtime is used.

We often need to tidy up files on our workstations or servers. Our applications may produce logs or temporary files. One common use case is to delete files that are above a certain age. The find command even provides a delete capability that we can use. The action flag -delete asks find to delete all the files it finds. We should note that this will look recursively through the file system hierarchy , starting from the current working directory.
