-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 {}/;
=================================================
Query for files modified on the day
[[email protected] class]# Find/-mtime-1-type f-exec ls-l {}/;
=================================================
Query the file and ask if you want to display
[[email protected] class]# Find/-mtime-1-type f-ok ls-l {}/;
< LS .... /classdb.inc.php >? Y
-rw-r--r--1 cnscn cnscn 13709 January 12:22./classdb.inc.php

Query and give it to awk to handle it.

1) Find all the *.h in/tmp and look for "syscall_vector" in these files, and finally print out all the filenames that contain "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 {}/;
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 *.c-exec cp ' {} '/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"
