hush

I redirected env into a file, and then altered it a little so that I could set the environmental variables when a script is executed.

I was having a problem when the script was being executed by cron.

In the end it worked out ok but I was wondering if anyone could explain each part of the command I added or has a link to a page that had some info on it. I found the command in a scripting book and then again on the web but neither of them went into any detail.

I hate using code that I don’t understand.


This is what I think is happening:
The PATH=/usr/local/bin sets the variable to what ever is on the right hand side of the =

Export PATH exports the variable, as it is a global variable it is able to do this (can some one confirm this is correct)

$PATH: was on a line that followed PATH=/usr/local/bin so I assume this somhow appends the string within the variable (this is a guess and the part I am most confused by). What is the “:” all about?.
