[ilugd]: Handling of error 'permission denied'

[gurdeep]

Hi Folks,   After installation of linux on our system, many of us may have encountered the problem of permission denied error eg.   When someone logs in he may come across of such kind of error of permission denial (Shell-Init). Now, In my case if I am trying to run the cat command to check the connectivity of my modem by issuing the command cat > /dev/ttyS1 I am also encountered by the error bash:/dev/ttyS1:permission denied.   All this need that our root directory and all the directories up to our home directory must be readable and executable by everybody. Is there anyone who can help me for how to fix this problem, I shall be thankful to him.   Best Regards, Malkiat   Pl. also reply at [EMAIL PROTECTED]
