linux The way to list all files and subdirectories in a folder is to use: ls command.
ls [选项] [目录名]
ls command usage example:
Example 1: List the details of all files and directories under the /home folder:
ls -l -R /home
There must be a dash "-" before the command parameter. The above command can also be written like this:
ls -lR /home/pythontab
Example 2: List the detailed contents of all directories starting with "t" in the current directory , you can use the following command:
ls -l t*
If you omit the command parameters and operation objects and enter "ls" directly, the contents of the current working directory will be listed.
Example 3: List only the folders in the directory
ls -F /home |grep /$
Output:
[root@localhost opt]# ls -F /opt/soft |grep /$ jdk1.6.0_16/ subversion-1.6.1/ tomcat6.0.32/
Example 4: List all files in the current working directory whose names begin with s, After the latest troubleshooting, you can use the following command:
ls -ltr s*
Example 5: List all files and directories in the current working directory; add "/" after the name of the directory, and add "" after the name of the executable file *"
ls -AF
Output:
[root@localhost opt]# ls -AF log/ script/ soft/ src/ svndata/ web/
Example 6: Calculate the number of files and directories in the current directory
ls -l * |grep "^-"|wc -l ---文件个数 ls -l * |grep "^d"|wc -l ---目录个数
Example 7: List the absolute paths of files in ls
ls | sed "s:^:`pwd`/:"
Output:
[root@localhost opt]# ls | sed "s:^:`pwd`/:" /opt/log /opt/script /opt/soft /opt/src /opt/svndata /opt/web
Example 9: List the absolute paths of all files (including hidden files) in the current directory, without recursion on the directory
find $PWD -maxdepth 1 | xargs ls -ld
Output:
[root@localhost opt]# find $PWD -maxdepth 1 | xargs ls -ld drwxr-xr-x 8 root root 4096 10-11 03:43 /opt drwxr-xr-x 2 root root 4096 2012-03-08 /opt/log drwxr-xr-x 2 root root 4096 2012-03-08 /opt/script drwxr-xr-x 5 root root 4096 10-11 03:21 /opt/soft drwxr-xr-x 2 root root 4096 2012-03-08 /opt/src drwxr-xr-x 4 root root 4096 10-11 05:22 /opt/svndata drwxr-xr-x 4 root root 4096 10-09 00:45 /opt/web
Example 10: Recursively list the absolute paths of all files (including hidden files) in the current directory
find $PWD | xargs ls -ld
Example 11: Specify the file time output format
ls -tl --time-style=full-iso
-a, –all lists all files in the directory, including implicit files starting with .
-A is the same as -a, but does not list "." (indicates the current directory) and ".." (indicates the parent directory of the current directory).
-c With -lt: Sort by ctime and display ctime (the time when the file status was last changed) With -l: Display ctime but sort by name Otherwise: Sort by ctime
-C Every The columns list items from top to bottom
–color[=WHEN] controls whether to use color resolution files. WHEN can be one of 'never', 'always' or 'auto'
-d, –directory displays the directory as a file, rather than displaying the files under it.
-D, –dired produces results suitable for the dired mode of Emacs
-f does not sort the output files, the -aU option is effective, and the -lst option is invalid
-g is like -l, but does not list the owner
-G, –no-group does not list any information about the group
-h, –human-readable for easy understanding The format lists the file size (for example, 1K 234M 2G)
-si is similar to -h, but the file size is taken to the power of 1000 instead of 1024
-H, –dereference-command-line Use the real destination indicated by a symbolic link in the command line
–indicator-style=Mode specifies an indicator after each project name
-i, –inode prints out the inode number of each file
-I, –ignore= style does not print out any wildcard characters that match the shell The item
-k of
