UNIX for Dummies Questions & Answers

Hello, I have a file with a list of car makes and specific information for each make. An example is:

@Audi:Warranty
@Audi:Pricing
@Audi:Colors
@Acura:Warranty
@Acura:Pricing
@Acura:Colors

and so on through a bunch of makes. I need to make a list in a selection box of just one name of each make. For example:

Audi
Acura
BMW
Buick

Any help is muchly appreciated! Thanks!

Inefficient but it will work:

Code:

$ sed 's|@||g' yourfile | awk -F\: '{print $1} | sort | uniq'

A similar way. Only slightly less efficient:

Code:

awk -F: '{print $1}' filename|sort|uniq|tr -d '@'

Code:

awk -F: '{ print $1 }' <Sample File name>|awk -F@ '{ print $2 }' | sort | uniq

Just noticed that this is a duplicate post.
