I would like to give 755 permissions to a directory, so I use:
# chmod -R 755 /my/folder/
It works for all files inside my folder, but the problem is that I use scripts that create new files in this folder, and by default the permissions are 600.
How could I impose, 755 permissions on these 'future' files ?
–EDIT–
I use a script that gives me info about network traffic on my campus. I have a new file every 10 minutes, located in a folder called journey, located in the month folder like this :
ls -lrt /home/netmet/secure/2017-04/2017-04-27/
total 118548

-rwxr-sr-x 1 root root 21854 avril 27 03:10 zzaccounting.dmp-03-00
Here I changed permissions by hand but when new the file appears, I have this :
-rw------- 1 root root 3479106 avril 27 15:50 zzaccounting.dmp-15-40
The thing is that for every folder and file under /home/netmet/secure/ I want 755 permision by default.
I have already done this :
chmod -R g+s /home/netmet/secure
setfacl -d -m g::rwx /home/netmet/secure
setfacl -d -m o::rx /home/netmet/secure

Try to run
umask
in your folder. If it returns anything other than '0022' then this is your problem. In your case it should initialy output '0177'. The permission system when creating directory is basically computed:default - umask
0777 is the default mode for directories, and 0666 to ordinary files, but there are different umasks, if I understand these things right. Try to executeumask a=rx,uu+w
.EDIT: You can use umask to give execute bit to directory to be able to cd into it, but not to files. These have to be given execute bit manually because of security. Simply add
chmod +x <file>
to your script. And, execute flag set on file anything other than executable has no effect.
