How to change permissions for a folder and its subfolders files in one step

Question

I would like to change the permissions of a folder and all its subfolders and files in one step  command  in Linux  I have already tried the below command but it works only for the mentioned folder  chmod 775  opt lampp htdocs  Is there a way to set chmod 755 for  opt lampp htdocs and all of its content including subfolders and files  Also  in the future  if I create a new folder or file inside htdocs  how can the permissions of that automatically be set to 755  I had a look at this link too  How to set default CHMOD in LINUX terminal

For anyone still struggling with permission issues  navigate up one directory level cd    from the root directory of your project  then add yourself  user  to the directory and give permission to edit everything inside  tested on Mac OS   To do that you would run this command  preferred   sudo chown -R username  foldername     note  for currently unsaved changes  might need to restart the code editor first to be able to save without being asked for a password  Also  please remember you can press tab to see the options while typing username and folder to make it easier for yourself   or simply  sudo chmod -R 755 foldername  but as mentioned above  need to be careful with the second method

You can use -R with chmod for recursive traversal of all files and subfolders   You might need sudo as it depends on LAMP being installed by the current user or another one   sudo chmod -R 755  opt lampp htdocs

You want to make sure that appropriate files and directories are chmod-ed permissions for those are appropriate  For all directories you want   find  opt lampp htdocs -type d -exec chmod 711         And for all the images  JavaScript  CSS  HTML   well  you shouldn t execute them  So use  chmod 644 img   js   html     But for all the logic code  for instance PHP code   you should set permissions such that the user can t see that code   chmod 600 file

The other answers are correct  in that chmod -R 755 will set these permissions to all files and subfolders in the tree  But why on earth would you want to  It might make sense for the directories  but why set the execute bit on all the files    I suspect what you really want to do is set the directories to 755 and either leave the files alone or set them to 644  For this  you can use the find command  For example   To change all the directories to 755  drwxr-xr-x    find  opt lampp htdocs -type d -exec chmod 755         To change all the files to 644  -rw-r--r--    find  opt lampp htdocs -type f -exec chmod 644

chmod 755 -R  opt lampp htdocs will recursively set the permissions  There s no way to set the permissions for files automatically in only this directory that are created after you set the permissions  but you could change your system-wide default file permissions with by setting umask 022

You can change permission by using following commands sudo chmod go rwx  opt lampp htdocs

Use   sudo chmod 755 -R  whatever your directory is   However  be careful with that  It can really hurt you if you change the permissions of the wrong files folders

For already created files  find      -type f -exec chmod g r o r               -type d -exec chmod g rx o rx            For future created files  sudo nano  etc profile  And set  umask 022  Common modes are   077  u rw g  o  007  u rw g rw o  022  u rw g r o r 002  u rw g rw o r

Here s another way to set directories to 775 and files to 664  find  opt lampp htdocs      -type f -exec chmod ug rw o r                 -type d -exec chmod ug rwxs o rx           It may look long  but it s pretty cool for three reasons   Scans through the file system only once rather than twice  Provides better control over how files are handled vs  how directories are handled  This is useful when working with special modes such as the sticky bit  which you probably want to apply to directories but not files  Uses a technique straight out of the man pages  see below    Note that I have not confirmed the performance difference  if any  between this solution and that of simply using two find commands  as in Peter Mortensen s solution   However  seeing a similar example in the manual is encouraging  Example from man find page  find        -perm -4000 -fprintf  root suid txt   m  u  p n           -size  100M -fprintf  root big txt  -10s  p n     Traverse the filesystem just once  listing setuid files and direct- tories into  root suid txt and large files into  root big txt   Cheers

chmod -R 755 directory name works  but how would you keep new files to 755 also  The file s permissions becomes the default permission

User · Answer

Check the -R option   chmod -R  lt permissionsettings gt   lt dirname gt   In the future  you can save a lot of time by checking the man page first   man  lt command name gt    So in this case   man chmod

You might want to consider this answer given by nik on superuser and use  one chmod  for all files folders like this   chmod 755   find  path to base dir -type d  chmod 644   find  path to base dir -type f

There are two answers of finding files and applying chmod to them  First one is find the file and apply chmod as it finds  as suggested by  WombleGoneBad    find  opt lampp htdocs -type d -exec chmod 755         Second solution is to generate list of all files with find command and supply this list to the chmod command  as suggested by  lamgesh    chmod 755   find  path to base dir -type d    Both of these versions work nice as long as the number of files returned by the find command is small  The second solution looks great to eye and more readable than the first one  If there are large number of files  the second solution returns error   Argument list too long   So my suggestion is   Use chmod -R 755  opt lampp htdocs if you want to change permissions of all files and directories at once  Use find  opt lampp htdocs -type d -exec chmod 755       if the number of files you are using is very large  The -type x option searches for specific type of file only  where d is used for finding directory  f for file and l for link  Use chmod 755   find  path to base dir -type d  otherwise Better to use the first one in any situation

To set to all subfolders  recursively  use -R  chmod 755  folder -R   And use umask to set the default to new folders files     cd  folder     umask 755

I think Adam was asking how to change umask value for all processes that tying to operate on  opt lampp htdocs directory   The user file-creation mode mask  umask  is use to determine the file permission for newly created files  It can be used to control the default file permission for new files   so if you will use some kind of ftp program to upload files into  opt lampp htdocs you need to configure your ftp server to use umask you want   If files   directories be created for example by php  you need to modify php code    lt  php umask 0022      other code   gt    if you will create new files   folders from your bash session  you can set umask value in your shell profile    bashrc  Or you can set up umask in  etc bashrc or  etc profile file for all users  add the following to file  umask 022  Sample umask Values and File Creation Permissions If umask value set to   User permission     Group permission     Others permission 000                         all              all                   all 007                         all              all                   none 027                         all          read   execute            none   And to change permissions for already created files you can use find  Hope this helps

If you want to set permissions on all files to a r  and all directories to a x  and do that recursively through the complete subdirectory tree  use   chmod -R a rX     The X  that is capital X  not small x   is ignored for files  unless they are executable for someone already  but is used for directories
