bash: adding new items to a list

Xeratul · 11-19-2012, 12:14 AM

Hi,

I would like to add some new items from list.txt to a given file. However I would like that no dubblets (line check) exists. It is a txt.

Would you mind helping to know how to remove the possible dubblets?

Code:

 cat list.txt >> "$varlist"

thank you in advance

is this list sorted? In that case you can use sort -u. Otherwise you will need a script (perl/awk/whatever)

what are "dubblets"?

This may help?
