Currently it seems to be 664
,how can I change it to 700
?
You can use the umask command to change the file creation mask. This though only masks bits. If the application creating the file does not request a bit to be set then umask wont set it. With a umask 077
then files will generally be created 600
and directories 700
You can set your default umask in your $HOME/.profile
You want to use umask
sente@oslo: $ umask
0022
sente@oslo: $ umask -S
u=rwx,g=rx,o=rx
sente@oslo: $ touch foo
sente@oslo: $ ls -l foo
-rw-r--r-- 1 sente pg2662512 0 2011-08-02 23:13 foo
sente@oslo: $ umask -S u=rwx,g=,o=
u=rwx,g=,o=
sente@oslo: $ touch bar
sente@oslo: $ ls -l bar
-rw------- 1 sente pg2662512 0 2011-08-02 23:13 bar
I think you'll need to chmod u+x still.
sente@oslo: $ help umask
:
umask: umask [-p] [-S] [mode]
The user file-creation mask is set to MODE. If MODE is omitted, or if
`-S' is supplied, the current value of the mask is printed. The `-S'
option makes the output symbolic; otherwise an octal number is output.
If `-p' is supplied, and MODE is omitted, the output is in a form
that may be used as input. If MODE begins with a digit, it is
interpreted as an octal number, otherwise it is a symbolic mode string
like that accepted by chmod(1).
