A Guide on Modifying File Permissions for an Entire Directory
The use of a certain method will group the file names together before executing a sub-process for that particular group of files. Solution 1: In PHP, the function allows you to modify the file permissions. For recursive changes, execute the command using exec. Make sure that the webserver has write access to the folder. For more details, refer to the following resources: http://php.net/manual/en/function.chmod.php and http://www.w3schools.com/php/func_filesystem_chmod.asp. Solution 2: Although there is a lengthy way to accomplish this in PHP, personally, I would prefer using the command line which can be interacted with by PHP.
Chmod all files in a directory [duplicate]
find path_to_dir -type f -name "*.*" -exec chmod 775 <> \;
Specify the desired file type for which you want to modify permissions. Applying *.* will result in changes being applied to all files within the directory.
Linux — How to chmod all files in sub-directories without, I have tried to chmod 444 for every HTML file in all sub-directories, but all files and folders were changed to 444 when I tried this command: chmod -R 444 /home/ppp/ *.html. I just want to chmod all HTML files in /home/ppp folder and sub-folders, but not for folders and other file types. linux centos debian chmod.
How to set chmod for a folder and all of its subfolders and files in PHP? [duplicate]
The PHP function enables the modification of file permissions, and for recursively changing permissions, the «exec» command can be utilized.
exec ("find /path/to/folder -type d -exec chmod 0770 <> +");//for sub directory exec ("find /path/to/folder -type f -exec chmod 0644 <> +");//for files inside directory
Ensure that the Folder has write access granted to your web server.
For more detailed information, please refer to the following links regarding the chmod function in PHP: — http://php.net/manual/en/function.chmod.php — http://www.w3schools.com/php/func_filesystem_chmod.asp
In PHP, there are two ways to accomplish this task: a verbose method and a more preferable method involving command line interaction.
In the Linux/Unix command line, you have the option to execute the following command: chmod options permissions filename .
To alter permissions in a recursive manner, one would execute the following command: chmod -R 0777 masterFile .
In PHP, the code exec(«chmod -R 0777 masterFile»); would be used.
The letter «R» signifies recursion, allowing it to delve into your sub-folders.
Instead of the lengthy process in PHP, which involves obtaining an array of sub folders and executing a foreach loop to apply the chmod() function, this alternative method is more efficient.

Linux — How to remove all the files in a directory?, I am trying to remove all files and subdirectories in a directory. I used rm -r to remove all files, but I want to remove all files and subdirectories, excluding the top directory itself.. For example, I have a top directory like images.It contains the files header.png, footer.png and a subdirectory.. Now I want to delete header.png, …
Changing chmod for files but not directories
An effective response, find -exec , has a minor drawback of generating a distinct sub-process for each file, which is typically unrelated. Nevertheless, it remains fully functional and only exhibits poor performance when dealing with a significantly high number of files. By utilizing xargs , the file names can be grouped together and processed as a batch, thereby mitigating this issue.
It is important to exercise caution when using xargs , as you need to ensure that filenames containing spaces, newlines, or other special characters are handled correctly.
A viable solution to address both of these issues involves having a sufficiently good implementation of find and xargs .
find . -type f -print0 | xargs -0 chmod 644
The usage of -print0 results in the termination of file names on its output stream with a NUL character instead of a space. Additionally, when -0 is applied, it informs the program to anticipate this NUL character as the input format.
One alternative approach to achieve this is by employing find . -exec . in the following manner:
find . -type f -exec chmod 644 <> \;
The inefficiency arises from the fact that the -exec initiates a chmod process for each file. To mitigate this issue, a solution can be implemented.
find . -type f -exec chmod 644 <> +
The chmod command line process collects multiple file name arguments, while the find . | xargs . approach follows a similar pattern and can be found in the accepted answer.
Please note that the use of back-ticks will cause issues if there are an excessive number of files to be chmoded or if the combined length of the pathnames is too large.
To modify all files in the current directory and its subdirectories, use this method recursively. If you wish to target a different directory, simply replace . with the appropriate path.
$ chmod 644 `find /home/my/special/folder -type f`
How to chown/chmod all files in current directory?, You want to use chown username:groupname *, and let the shell expand the * to the contents of the current directory. This will change permissions for all files/folders in the current directory, but not the contents of the folders.
Default chmod for new files in one specific folder
Please refer to the answer titled «Default permissions,» which is sourced from the page on «Default files permissions in a specific folder.
That should be what you’re seeking. This ensures that any newly created files will adhere to the default settings.
Explore PHP’s umask() function, which allows you to set file permissions. For instance, by using umask(000), you can ensure that all newly created files will have read and write access for the owner, group, and others.
I’m uncertain about the possibility of altering the default file permissions for a new file. Even if it is feasible, I’m unsure if setting it to 777 is advisable.
Instead, I suggest using an alias and creating a custom command that modifies the permissions of newly created directories.
alias chmodd='function _chmodd()< mkdir "$1" ; chmod 777 "$1" ; >; _chmodd'
How to set chmod for a folder and all of its subfolders, On the command line (Linux/Unix) you can do chmod options permissions filename To recursively change permissions you would do chmod -R 0777 masterFile So in PHP you would do exec («chmod -R 0777 masterFile»); -R means recursive so it would go to your sub-folders
Changing file and folder permissions recursively within a directory using chmod/chown/chgrp
To illustrate, you can search for: — All files in the current directory — All entries, which include files, directories, and other items By default, the find function treats regular and hidden files equally, except for the «.» file which it excludes. To exclude hidden files altogether, you can add a comma. On the other hand, if you only want to operate on hidden files, you can add a «.».
Recursively chmod/chown/chgrp all files and folder within a directory
This could prove beneficial as syntax errors have been rectified through editing.
function fsmodify($obj) < $chunks = explode('/', $obj); chmod($obj, is_dir($obj) ? 0755 : 0644); chown($obj, $chunks[2]); chgrp($obj, $chunks[2]); >function fsmodifyr($dir) < if($objs = glob($dir."/*")) < foreach($objs as $obj) < fsmodify($obj); if(is_dir($obj)) fsmodifyr($obj); >> return fsmodify($dir); >
You can perform a system call
system("/bin/chmod -R $mod $root"); system("/bin/chown -R $user $root"); system("/bin/chgrp -R $user $root");
To prevent the execution of arbitrary commands, it is necessary to utilize either escapeshellarg() or escapeshellcmd().
system("/bin/chmod -R $mod $root"); system("/usr/bin/find -type d $root -print0 | xargs -0 | /bin/chmod $moddir"); system("/bin/chown -R $user $root"); system("/bin/chgrp -R $user $root");
When encountering mode 493 error, it indicates that the mode was passed in decimal format. To resolve this error, the mode must first be converted to an octal string.
Chmod all files (including hidden files) in a directory in, For example: All files in the current directory: find . -maxdepth 1 -type f. All entries (files+directories+others): find . -maxdepth 1. Find doesn’t normally distinguish between regular files and «hidden» files, but it does not include If you want it to ignore them you can add ‘!’ -name ‘.*’, if you want it to operate only on dot files …
Recursively apply a command to modify all files in a directory
As per my comprehension, it seems that you have the ability to convert a single file.
./convert /path/to/file >/path/to/file.new mv /path/to/file.new /path/to/file
To perform a command on all files in a directory tree, utilize the find tool. As you are required to run a complicated command on each file, it is necessary to explicitly call a shell.
find /path/to/top/directory -type f -exec sh -c ' /path/to/convert "$0" >"$0.new" && mv "$0.new" "$0" ' <> \;
The linked question’s functionality is limited to a single level, lacking recursion. To achieve recursion, implement find .
find . -type f -exec /path/to/convert <> \;
You aim to relocate convert from the tree you’re traversing to prevent any attempt by it to modify itself.
It seems like you aim to replace the content of every input file with the output of convert for that particular file. In that case, you can attempt the following solution:
find . -type f | while IFS= read -r file; do ./convert "$file" > /tmp/foo.tmp && mv /tmp/foo.tmp "$file"; done
Shell — Recursively apply a command to modify all files in, To apply a command to every file in a directory tree, use the find utility. Since you need to execute a complex command for each file, you need to invoke a shell explicitly. find /path/to/top/directory -type f -exec sh -c ‘ /path/to/convert «$0″ >»$0.new» && mv «$0.new» «$0» ‘ <> \; Share Improve this answer answered Oct 16, …
Recursively merge all files under a root directory
Use find with two -exec options:
find $YOUR_DIR -iname '*.csv' -exec cat <> \; -exec echo \;
Additionally, in case your CSV files contain a header, you could consider utilizing sed 1d to eliminate the initial line, instead of repeatedly using cat .
find $YOUR_DIR -iname '*.csv' -exec sed 1d <> \; -exec echo \;
Bash — Is there a shell command to recursively give, First line changes file permissions, and the second changes directory permissions in the active directory and its subdirectories. find . -type f -print0 | xargs -0 chmod 644 find . -type d -print0 | xargs -0 chmod 755
Chmod all files (including hidden files) in a directory in Linux (not recursively)
In case you use bash, by defining dotglob you can make files starting with a . also be recognized by * .
You mentioned not wanting to use «find», but it is actually a suitable tool for this task due to its extensive functionality. You have the ability to specify whether or not to search recursively, modify directories, and more. A prime example is:
- The files present in the current directory can be found using the following MSDT code: find . -maxdepth 1 -type f .
- The list includes all types of entries such as files, directories, and others labeled as find . -maxdepth 1 .
By default, the «find» command doesn’t differentiate between regular files and hidden files. However, it excludes .. . To exclude hidden files from the search, you may use ‘!’ -name ‘.*’ . Conversely, if you only want to operate on dot files, you can use -name ‘.*’ .
An additional benefit is that you can view the entries that the operation will be performed on by adding «| less» at the end. This review process could have potentially avoided the issue you encountered.
After selecting a suitable find command, you can execute the chmod command by appending -exec chmod o-rwx ‘<>‘ ‘;’ at the end. If your find supports it, replace ‘;’ with + .
Utilizing the «find» tool is highly recommended in this scenario, as it is precisely what is needed and should not be avoided.
Although it may not be entirely trustworthy since it may overlook dotfiles with unusual names (such as .+baz ), the tool is brief and upbeat. However, given the rarity of such cases, I have learned to utilize it effectively.
