linux include all directories
how would I type a file path in ubuntu terminal to include all files in all sub-directories?
If I had a main directory called «books» but had a ton of subdirectories with all sorts of different names containing files, how would I type a path to include all files in all subdirectories?
Solution
It is unclear what you actually want . Probably you will get a better solution to your problem, if you ask directly for it, not for one other problem you’ve come accross trying to circumvent the original problem.
do you mean something like the following?
where the first * expands for all subdirectories and the second * for all contained files ?
I have chosen the file command arbitrarily. You can choose whatever command you want to run on the files you get shell-expanded. Also note that directories will also be included (if not excluded by name, e.g. *.png or *.txt ). The wildcard * is not exactly the file path to include all files in all subdirectories but it expands to all files (or directories) matching the wildcard expression as a list, e.g. file1 file2 file3 file4 . See also this tutorial on shell expansion.
Note that there may be easy solutions to related problems. Like to copy all files in all subdirectories ( cp -a for example, see man cp ).
I also like find very much. It’s quite easy to generate more flexible search patterns in combination with grep . To provide a random example:
du `find . | grep some_pattern_to_occur | grep -v some_pattern_to_not_occur` Code Example: Locating Files in Linux Subdirectories
There are three solutions to the problem at hand. The first solution involves using a command from within the top directory of the books. You can then use xargs command to run each file through cat. For more information, use the provided commands. The second solution involves providing a random example since it is unclear what is actually wanted. In the third solution, assuming you are in the parent directory of ‘books’, you can use the TCL file commands to list the tree recursively. Building on ramanman’s reply, the first solution offers a routine that works its way down the directory tree recursively using the built-in TCL file commands.
Linux include all directories
You can utilize the command by being in the top directory of the book.
If you desire to execute the cat command on every file, you can make use of the xargs command.

The desired outcome is uncertain. To receive an effective solution, it is recommended to request assistance directly for the original problem instead of attempting to bypass it by presenting a separate issue.
Are you suggesting a statement similar to this one?
Is it correct to say that the * is meant to apply to all subdirectories, while * is intended for all files within those subdirectories?
The command file has been arbitrarily selected, but feel free to choose any command you’d like to run on the shell-expanded files. It’s important to note that directories will also be included, unless explicitly excluded by name, such as *.png or *.txt . While the wildcard * doesn’t exactly represent the file path to include all files in subdirectories, it does expand to include all files or directories that match the wildcard expression as a list, for example file1 file2 file3 file4 . For more information on shell expansion, check out this tutorial.
It should be noted that there could be simple resolutions for similar issues. For instance, if you need to duplicate all documents in each subfolder, you can refer to the code provided in man cp .
I’m also fond of find . When combined with grep , it allows for the creation of more adaptable search patterns. As an illustration, consider the following arbitrary scenario:
du `find . | grep some_pattern_to_occur | grep -v some_pattern_to_not_occur` As an illustration, let’s assume that I am located in the main directory and ‘books’ is a subdirectory.
In order to recursively list all the trees, the appropriate method to employ is:
List all files in a directory and subdirectory linux Code, ubuntu command ls options. get list of files in directory without sub directories. get all file names in a folder and subfolders. Find / -name ‘*’ willList all files and directories recursively starting from /List a file named * in /List all files in / directoryList all files and directories in / directory.
TCL: Recursively search subdirectories to source all .tcl files
Expanding on ramanman’s response, here’s a script that addresses the issue by utilizing TCL’s pre-installed file commands and methodically traverses the directory hierarchy.
# findFiles # basedir - the directory to start looking in # pattern - A pattern, as defined by the glob command, that the files must match proc findFiles < basedir pattern >< # Fix the directory name, this ensures the directory name is in the # native format for the platform and contains a final directory seperator set basedir [string trimright [file join [file normalize $basedir] < >]] set fileList <> # Look in the current directory for matching files, -type # means ony readable normal files are looked at, -nocomplain stops # an error being thrown if the returned list is empty foreach fileName [glob -nocomplain -type -path $basedir $pattern] < lappend fileList $fileName ># Now look for any sub direcories in the current directory foreach dirName [glob -nocomplain -type -path $basedir *] < # Recusively call the routine on the sub directory and append any # new files to the results set subDirList [findFiles $dirName $pattern] if < [llength $subDirList] >0 > < foreach subDirFile $subDirList < lappend fileList $subDirFile >> > return $fileList > With tcllib incorporated, the task becomes effortless.
package require fileutil foreach file [fileutil::findByPattern $basepath *.tcl]
Possibly more compatible with various platforms and utilizing built-in commands instead of relying on process piping.
foreach script [glob [file join $basepath folderA *.tcl]]
If your selection criteria are stricter and you don’t need to consider other platforms, the use of «find» could offer greater versatility.
Linux command to find a file in all subdirectories Code, look for all files in the current directory and in all of its subdirectories in linux grep list files in all subdirectories linux select all files in directory and subdirectories
How to list the files inside directory and sub directories?
It provides a list of all the files with the extension ‘.txt’ in the root directory.
find /where/to/search -name "*.txt" -type f By using the command to filter files by their extension, only those files that end with .txt will be listed. The -type f filter will exclude directories, even if their name ends with .txt.
The shell built-in command echo is likely the most efficient option for performing * expansion. However, if you require additional capabilities, it would be better to utilize ls instead of echo .
Linux — How can I recursively find all files in current and, find -L . -name «foo*». In a few cases, I have needed the -L parameter to handle symbolic directory links. By default symbolic links are ignored. In those cases it was quite confusing as I would change directory to a sub-directory and see the file matching the pattern but find would not return the …
linux include all directories
how would I type a file path in ubuntu terminal to include all files in all sub-directories? If I had a main directory called «books» but had a ton of subdirectories with all sorts of different names containing files, how would I type a path to include all files in all subdirectories? /books/.
in what context? in a scripting language or at the command line as input to a shell command? some more info would be useful..
Typically, if a tool supports this, there will be a flag that can be passed to the tool to recurse subdirectories.

From within the books top directory, you can use the command:
Then, if you wanted to, say run each file through cat, you could use the xargs command:
For more info, use commands:
This is the correct way to traverse a hierarchy of subdirectories. Some shells offer a wildcard syntax **/* for this but Bash v2 is not amongst them.
Any Ubuntu version that is yet supported uses bash version 3 or higher for the terminal (as far as I know).
