Thanks, that works.

My guess for "./" is "current directory" too, as in windows (DOS prompt window), (in the shape of ".\"), it meens "current directory" too.

Oh mighty and glorious moderator, would you mind moving the bits of this thread about building software under Linux into the Linux forum?

Begging your esteemed pardon, I remain

No mystery about that reason, it's a security feature.

You wouldn't want to cd into a freshly untar'd archive to "cat README" only to run a malicious ./cat instead (before asking why don't you just put ./ at the END of $PATH to avoid that? answer: because sometimes typos happen too, ./cat could as easily be ./catt or ./caat and be just as malicious if accidentally ran.)

People divide into two classes: those who add . to their $path and those who don't (including sysadmins and those who they control; in the '90s nobody cared). On your home computer you can add . to $path. At work, they will demand that you remove it.

Furthermore, people divide into those who never make mistakes (think B.Schneier) and those who do. If you are in the former, you don't need
alias rm 'rm -i'
in your .cshrc ... When you have it, it is easier to override it by typing \rm -rf *

I've encountered that; oddly I can move whole threads into forums I don't moderate.
