Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:
Consider the following simple situation [ reading something using while and read ]
[See script 1 in sample output]
The variable var is assigned with "nullll" at first. Inside the while loop [piped while] it is assigned with "whillleeee". [Onlly 2 assignments stmts]. Outside the loop the last assigned value for "var" [and no variable] inside the while can't be accessed [Due to pipe, var is executed in a sub shell].
In these type of situation variables can be accessed by modifying as follows.
[See script 2 in sample output]
Vary helpful when reading a set of items, say file names, stored on a file [or variable] to an array an use it later.
Is there any other way 2 access variables inside and outside the loop ??
There are 6 alternatives - vote for the best!
