Re: [LI] c compiler

["Shanker R Swaminathan" <CseWhiz@xxxxxxxxxxxxx>]

type ./a.out to execute your program. In Unix, the programs you run are the
programs you have in your path unless you explicitly use an absolute
filename , i.e., one with the path( assuming you have the rights to
access/execute it). The current directory is NOT searched by default in
order to execute a file , unlike dos. This is so because having the current
directory in your path is one of the biggest security holes you could have.
Imagine some malicious program named ls. You go across to that directory and
type ls and THAT gets executed and does some damage to you , since it now
has access to your files. Think if you has root permissions!For more
information about this , refer to the Linux gazette , volume 45 if my memory
serves right.
