locate 命令 根据关键字在整个Linux系统中查找 定位
1.基于自己的数据库 对文件进行查找；会把匹配的文件全部给出

└─# locate -h
Usage: plocate [OPTION]... PATTERN...
-b, --basename search only the file name portion of path names
-c, --count print number of matches instead of the matches
-d, --database DBPATH search for files in DBPATH
(default is /var/lib/plocate/plocate.db)
-i, --ignore-case search case-insensitively
-l, --limit LIMIT stop after LIMIT matches
-0, --null delimit matches by NUL instead of newline
-N, --literal do not quote filenames, even if printing to a tty
-r, --regexp interpret patterns as basic regexps (slow)
--regex interpret patterns as extended regexps (slow)
-w, --wholename search the entire path name (default; see -b)
--help print this help
--version print version information

使用which 在PATH变量中查找可执行文件
- PATH变量：路径搜索变量
- 查看变量 echo $变量名
- 路径之间用冒号分割
- 作用：当执行一个（外部）命令程序时，会在PATH变量中查找有无这个程序

find 功能强大的find命令
──(root㉿kali)-[~/work/exam]
└─# find --help
Usage: find [-H] [-L] [-P] [-Olevel] [-D debugopts] [path...] [expression]
Default path is the current directory; default expression is -print.
Expression may consist of: operators, options, tests, and actions.
Operators (decreasing precedence; -and is implicit where no others are given):
( EXPR ) ! EXPR -not EXPR EXPR1 -a EXPR2 EXPR1 -and EXPR2
EXPR1 -o EXPR2 EXPR1 -or EXPR2 EXPR1 , EXPR2
Positional options (always true):
-daystart -follow -nowarn -regextype -warn
Normal options (always true, specified before other expressions):
-depth -files0-from FILE -maxdepth LEVELS -mindepth LEVELS
-mount -noleaf -xdev -ignore_readdir_race -noignore_readdir_race
Tests (N can be +N or -N or N):
-amin N -anewer FILE -atime N -cmin N -cnewer FILE -context CONTEXT
-ctime N -empty -false -fstype TYPE -gid N -group NAME -ilname PATTERN
-iname PATTERN -inum N -iwholename PATTERN -iregex PATTERN
-links N -lname PATTERN -mmin N -mtime N -name PATTERN -newer FILE
-nouser -nogroup -path PATTERN -perm [-/]MODE -regex PATTERN
-readable -writable -executable
-wholename PATTERN -size N[bcwkMG] -true -type [bcdpflsD] -uid N
-used N -user NAME -xtype [bcdpfls]
Actions:
-delete -print0 -printf FORMAT -fprintf FILE FORMAT -print
-fprint0 FILE -fprint FILE -ls -fls FILE -prune -quit
-exec COMMAND ; -exec COMMAND {} + -ok COMMAND ;
-execdir COMMAND ; -execdir COMMAND {} + -okdir COMMAND ;
Other common options:
--help 显示此帮助信息并退出
--version output version information and exit
Valid arguments for -D:
exec, opt, rates, search, stat, time, tree, all, help
Use '-D help' for a description of the options, or see find(1)
Please see also the documentation at https://www.gnu.org/software/findutils/.

program via the GNU findutils bug-reporting page at
