A remark: adding the current working directory to your path is considered very dangerous. You cannot move around safely in any filesystem anymore. Just imagine, someone places a script called "ls" in his home or any directory which calls "rm -f" on your home or any other sensitive files. –  barbaz Oct 26 '11 at 19:57

Add a PATH=$PATH:. line to your ~/.bashrc. See this question for details.

Bear in my that adding current folder to the path is security risk, it exposes user of never knowing if its running command from some unsecured folder or a normal system command ( 'ls' for example) –  bbaja42 Oct 26 '11 at 16:48

And before someone claims that adding the current directory at the end of PATH is safe, an attacker can still run code as you by creating a program or script named after misspelled commands, such as mroe, tial, vmi, emasc, etc. Those won't be found earlier in the path, and then you end up running the attacker's code as you. –  Fran Jun 8 '12 at 20:42
