Hello all:
today I have two questions :
first question :in page 105
there was "If you want that value to be passed to other processes that you launch,use the export built-in command"
I opened other terminal then try this but it doesn't find it
Second one : in page 109
" kill `cat /var/run/named/named.pid` "
but output of 'cat' isn't parameter ,it's input to kill
then why Backticks , I expect PIPE is more suitable
waiting for your replies
