Linux chmod octal mode

Linux chmod octal mode-The chmod command stands for change mode and it's used to limit access to resources It's a same as using your mouse to rightclick a file or folder and selecting the permission tabs and defining who can access the resource the chmod command is the way to do it on the command lineChmod is a Unix command which changes the access bits (modes) on a file It can make a file readable, writable, or executable by the owner, people in the same group as the file, or everyone chmod can also be used to change the SUID, SGID or "sticky" bits

Use the octal CHMOD Command chmod R 0640 folder_name OR use the symbolic CHMOD Command chmod R arwx,ux,gwx,orwx,ugs,t folder_nameUse the octal CHMOD Command chmod R 0640 folder_name OR use the symbolic CHMOD Command chmod R arwx,ux,gwx,orwx,ugs,t folder_nameOwner can read, write and execute;

The way to set these bits with chmod in octal mode is to add a value prefix, such as 4755 to add setuid to an executable file In symbolic mode, the u and g can be used to set or remove setuid and setgid, such as us,gs The sticky bit is set using ot (Other combinations, like os or ut, are meaningless and ignored)We can present permissions as an octal number For example, for setting read, write & execute permissions for the owner, read & write permissions for its group, and no permission for others, to a hellotxt file, we will execute the following command sudo chmod u =rwe, g =rw,orwx hellotxtWe only use commas to separate them Another way to specify permission is by using the octal/numeric format

If you're wondering why that leading zero is important, it's because permissions are set as an octal integer, and Python automagically treats any integer with a leading zero as octal So oschmod ("file", 484) (in decimal) would give the same result What you are doing is passing 664 which in octal is 1230 In your case you would needThe command line usage for chmod mode looks like this chmod options newmode filename The new mode is specified in octal mode or symbolic mode We'll cover symbolic mode first In the first example we used gw to remove write permission for group As you might be able to guess, g stood for group, for remove and w represented write permissionThe first octal digit sets the setuid, setgid and sticky bits (see this article for more details on setuid/setgid) octal 2 means to set group ID on the file So, the equivalent would be to do a chmod arwx filename, then chmod gs filename The chmod info page does explain this in more detail
