Linux Find command detailed

use the Find command to delete all VSSVER2.SCC files under Linux

Delete all VSSVER2.SCC files

This is the purpose of my search for the Linux find command.

1) Find/-name ' VSSVER2.SCC ' | Xargs rm-rf #先 (Recursive) Find the current path contains VSSVER2.SCC files, and then kill each other by Xargs

# (processing is done one after the other, not a ' delete ' to delete a bar and then continue to delete ') find can also add-type D and other search directories

2) Find/-iname ' VSSVER2.SCC '-exec rm-rf {} \; #先 (recursive) found. File containing VSSVER2.SCC in the current path, then kill

-iname filename #同-name, difference-I ignores case find/*vssver2.scc*-exec rm-rf {} \;

Examples of find common usages in Linux

Find Path-option [-print] [-exec-ok command] {} \;

#-print output of the found file to standard output

#-exec command {} \; -the command operation of the file to be traced, {} and \; There is a space between {} and {} Indicates the result of find, and the last backslash \ and semicolon; Indicates the end of the command?

#-ok and-exec are the same, except to consult the user before operation

#find determine the path and expression according to the following rules (command option parameter-option), on the command column, the first-(),! The previous section is path, followed by expression. If path is an empty string, use the current path, and if expression is an empty string, use-print as the default expression.

Delete all. SVN directories

That's what I was looking for to find the Linux find command.

1) Find. -type d-name '. SVN ' | Xargs rm-rf #先 (Recursive) Find the file directory under the current path that contains. SVN, and then kill each one by Xargs.

# (processing is done one by one, not by deleting a clause and then continuing to delete it)

2) Find. -type d-iname '. SVN '-exec rm-rf {} \; #先 (recursive) found. The current path contains the. svn file directory, then kill

-iname filename #同-name, difference-I ignores case

-rw-r–r–1 root root 12959 2003-02-25./conf/magic

-rw-r–r–1 root root 2003-02-25./conf.d/readme

Check all the normal files in the current directory and use the LS-L command in the-e x E C option to list them

=================================================

In the/L o G S directory, look for files that change time before 5th and delete them:

$ find Logs-type f-mtime +5-exec-ok rm {} \;

=================================================

#查询当天修改过的文件

[Email protected]~$ Find/-mtime-1-type f-exec ls-l {} \;

=================================================

#查询文件并询问是否要显示

[Email protected]~/tmp$ Find/-mtime-1-type f-ok ls-l {} \;

< LS .... /.find.swo >? Yes

-rw-r--r--1 zgf zgf 20480 2010-06-30 23:48./.find.swo

1) Find all the *.h in/tmp and look for ' syscall_vector ' in these files, and finally print out all filenames containing ' syscall_vector '

A) find/tmp-name ' *.h ' | Xargs-n50 grep syscall_vector

B) grep syscall_vector/tmp/*.h | Cut-d ': '-f1| Uniq > FileName

C) find/tmp-name ' *.h '-exec grep ' syscall_vector ' {} \; -print

2) Find/-name filename-exec rm-rf {} \;

Find/-name filename-ok rm-rf {} \;

One way to #这个就是上面提到的删除. SVN directory

3) For example, to find files larger than 3M on the disk:

Find. -size +3000k-exec ls-ld {} \;

4) Copy the find out to another place.

Find *.txt-exec cp {}/home/zgf/tmp \;

If you have special files, you can use Cpio, or you can use this syntax:

Find Dir-name Filename-print | CPIO-PDV Newdir

6) Look for files changed at 2004-11-30 16:36:37

# a= ' Find/-name ' *php ' | Ls-l–full-time $A 2>/dev/null | grep ' 2004-11-30 16:36:37

Second, the use of the Linux find command

1. Basic usage:

Find/-name file name

Find ver1.d ver2.d-name ' *.c '-print finding ver1.d,ver2.d *.c files and printing

Find. -type D-print from the current directory, finds only the directory, and when found, prints the path name. Can be used to print the directory structure.

2. No Error Lookup:

Find/-name Access_log 2 >/dev/null

3. Search by Size:

Find/-size 1500c (look for a 1,500-byte file, c for bytes)

Find/-size +1500c (finds files larger than 1,500 bytes, + represents greater than)

Find/-size +1500c (finds files less than 1,500 bytes in size-Indicates less than)

4. By Time:

Find/-amin n last N minutes

Find/-atime n last n days

Find/-cmin n last N minutes change state

Find/-ctime N last n days change state

5. Other:

Find/-empty blank file, blank folder, folder without subdirectories

Find/-false files that are always wrong in the lookup system

Find/-fstype Type Locate the file that exists in the specified file system, such as type ext2

Find/-gid n set of files with ID n

Find/-group gname group file named Gname

Find/-depth N first search for file contents in a certain level of specified directory

Find/-maxdepth levels in a hierarchical directory in descending order

6. Logic

-and conditions and-or conditions or

7. Finding strings

Find. -name ' *.html '-exec grep ' mailto: ' {} \;
