Linux下如何统计文件数目

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
