Indentation help
Hi
I have coded 300 line script.Its not indented properly.i am not good at indentation.
I would appreciate your help on this.
i want to use a 4 space indentataion.Hence if i "set tabstop=4" and use tabs for coding and if some one else open
this script in their system it looks unindented since default value for tab is 8.
I have tried beautify ruby script but ruby script fails.
I would appreciated help
1)Any utility to beautify by apply indentation
2)Any documenation for indentation for korn shells.
3)Any standards for identation and its procedure for very long scripts.

What does your editor of choice do to tabs? What is your editor, for that matter? Tabs should still be there even if differently sized unless your editor does something weird.

try 'setterm -regtabs 4' to make a console have tabs at 4 spaces. In my case I had to force it with 'TERM=linux setterm -regtabs 4'

The only way to get consistent indentation is to use paces, not tabs.

My editor (GNU emacs) handles indentation nicely for most langauges, and it's customizable.

I have downloaded GNU emacs.
I put some code on editor on my windows machine.

I pressed cntl+alt+\

It did not indent my code.
Can please help how the emac will automatically indent all my 300 script shell.

At the top of the buffer, press Ctrl+<space>, move to the bottom of the buffer and press cntl+alt+\

A buffer is the area that stores your file.

I could have said, "Go to the top of your file."

(You can have many buffers open at once. I typically have 50.)
