LINUX中 設定了umask 建立的預設檔案和目錄的權限
普通檔案預設是644 也就是:
-rw-r--r-- 1 root root 0 May15 20:04 test
自已有讀寫(rw),同組人員有讀(r),其它有讀(r)
預設權限可通過umask 修改
預設umask 為022
檔案:666 - 022 = 644
目錄:777 - 022 = 755
如果你下了umask 011 的指令，則生成的檔案目錄權限就變成:
檔案:666 - 011 = 655
目錄:777 - 011 = 766
修改 .bash_profile 檔案就可以了
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
alias ls='ls -CF'
PS1='SZDATA_suheadof:$PWD> '; export PS1
umask 022 #########就是這個問題
