which program will execute

[Henry Chua]

Hi Guys

Just curious, say I have a shell script "kk.sh", if I have it in /bin, and another in /usr/bin and other paths..all different...which one will be executed if i run it in root shell? what is the hierachical tree for program execution?

Henry:

Type:

echo $PATH

from ypur shell prompt - this will give you a : delimited list of your seach path when attempting to execute a script/executable etc.

A quick way to find out which one will run is to type:

which kk.sh

# echo $PATH
This should give you the sequence of the paths that
is used to search the executable if you are not using
the absolute path. If your $PATH looks like following

/bin:/usr/bin/:.

then /bin/kk.sh will be executed.
