Change all files and folders permissions of a directory to 644 755

Question

How would I change all files to 644 and all folders to 755 using chmod from the linux command prompt   Terminal

User · Answer

The easiest way is to do   chmod -R u rwX go rX go-w  path to dir   which basically means   to change file modes -Recursively by giving    user  read  write and eXecute permissions  group and other users  read and eXecute permissions  but not -write permission    Please note that X will make a directory executable  but not a file  unless it s already searchable executable       X - make a directory or file searchable executable by everyone if it is already searchable executable by anyone    Please check man chmod for more details   See also  How to chmod all directories except files  recursively   at SU

The shortest one I could come up with is   chmod -R a r u w a X  foo   which works on GNU Linux  and I believe on Posix in general  from my reading of  http   pubs opengroup org onlinepubs 9699919799 utilities chmod html    What this does is    Set file directory to r  r  r    0444  Add w for owner  to get rw r  r    0644  Set execute for all if a directory  0755 for dir  0644 for file     Importantly  the step 1 permission clears all execute bits  so step 3 only adds back execute bits for directories  never files   In addition  all three steps happen before a directory is recursed into  so this is not equivalent to e g   chmod -R a r  foo chmod -R u w  foo chmod -R a X  foo   since the a r removes x from directories  so then chmod can t recurse into them

One approach could be using find   for directories  find  desired location -type d -print0   xargs -0 chmod 0755   for files  find  desired location -type f -print0   xargs -0 chmod 0644

Do both in a single pass with   find -type f     -o -type d       As in  find type f OR type d  and do the first     for files and the second     for dirs   Specifically   find -type f -exec chmod --changes 644      -o -type d -exec chmod --changes 755        Leave off the --changes if you want it to work silently

On  https   help directadmin com item php id 589 they write   If you need a quick way to reset your public html data to 755 for directories and 644 for files  then you can use something like this   cd  home user domains domain com public html find   -type d -exec chmod 0755       find   -type f -exec chmod 0644         I tested and     it works

Easiest for me to remember is two operations   chmod -R 644 dirName chmod -R  X dirName   The  X only affects directories
