Linux Shell 下的輸出重定向

Linux Shell 環境中支持輸入輸出重定向，用符號<和>來表示。0、1和2分別表示標準輸入、標準輸出和標準錯誤信息輸出。同時，還可以在這三個標準輸入輸出之間實現重定向，比如將錯誤信息重定向到標準輸出，可以用 2>&1來實現。Linux下還有一個特殊的文件/dev/null，它就像一個無底洞，所有重定向到它的信息都會消失得無影無蹤。如果想要正常輸出和錯誤信息都不顯示，則要把標準輸出和標準錯誤都重定向到/dev/null， 例如：
# ls >/dev/null 2>&1
注意：此處的順序不能更改，否則達不到想要的效果，此時先將標準輸出重定向到 /dev/null，然後將標準錯誤重定向到標準輸出，由於標準輸出已經重定向到了/dev/null，因此標準錯誤也會重定向到/dev/null，於是一切靜悄悄.
