若只是查看当前目录下的文件数目(除开.和..文件),使用下面的命令：

$ find ./ -type f | wc -l

若查看当前目录下面的所有文件，含.和..使用如下命令即可：

$wc -l

ps：find command and wc command

1、FIND命令

NAME

find - search for files in a directory hierarchy

SYNOPSIS

find [path...] [expression]

DESCRIPTION

This  manual page documents the GNU version of find.  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 section 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 first argument that begins with `-', `(', `)', `,', or `!' is taken

to  be  the  beginning  of  the expression; any arguments before it are

paths to search, and any arguments after it are the rest of the expres-

sion.   If  no  paths  are given, the current directory is used.  If no

expression is given, the expression `-print' is used.

find exits with status 0  if  all  files  are  processed  successfully,

greater than 0 if errors occur.

OPTIONS

All  options  always return true.  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.

-daystart

Measure times (for -amin,  -atime,  -cmin,  -ctime,  -mmin,  and

-mtime)  from  the  beginning of today rather than from 24 hours

ago.

-depth Process each directory's contents before the directory itself.

-follow

Dereference symbolic links.  Implies -noleaf.

-help, --help

Print a summary of the command-line usage of find and exit.

-maxdepth levels

Descend at most levels (a non-negative integer) levels of direc-

tories  below  the  command line arguments.  `-maxdepth 0' means

only apply the tests and actions to the command line  arguments.

-mindepth levels

Do  not apply any tests or actions at levels less than levels (a

non-negative integer).  `-mindepth 1' means  process  all  files

except the command line arguments.

-mount Don't  descend  directories  on other filesystems.  An alternate

name for -xdev, for compatibility with some  other  versions  of

find.

-noleaf

Do  not  optimize  by  assuming that directories contain 2 fewer

subdirectories than their  hard  link  count.   This  option  is

needed  when  searching  filesystems that do not follow the Unix

directory-link convention, such as CD-ROM or MS-DOS  filesystems

or  AFS  volume  mount  points.  Each directory on a normal Unix

filesystem has at least 2 hard  links:  its  name  and  its  `.'

entry.   Additionally,  its  subdirectories (if any) each have a

`..'  entry linked to that directory.  When find is examining  a

directory,  after it has statted 2 fewer subdirectories than the

directory's link count, it knows that the rest of the entries in

the directory are non-directories (`leaf' files in the directory

tree).  If only the files' names need to be examined,  there  is

no  need  to  stat  them;  this  gives a significant increase in

search speed.

-version, --version

Print the find version number and exit.

-xdev  Don't descend directories on other filesystems.

2、WC命令

wc - print the number of bytes, words, and lines in files

SYNOPSIS

wc [OPTION]... [FILE]...

DESCRIPTION

Print byte, word, and newline counts for each FILE, and a total line if

more than one FILE is specified.  With no FILE, or when FILE is -, read

standard input.

-c, --bytes

print the byte counts

-m, --chars

print the character counts

-l, --lines

print the newline counts

-L, --max-line-length

print the length of the longest line

-w, --words

print the word counts

--help display this help and exit

--version               output version information and exit
