Question

(I know there’s a similar post about this, but the solution given is not working for me as it only works for that case in particular.)

I have something like this (File1.txt):

digraph G {
1 [shape="oval" label= "Open"] 
... 
8->9 [style="dashed" label= "true"]
...
2 [shape="oval" label= "Close"] 
8->9 [style="dashed" label= "true"]
...
}

And I want a new file that looks like this (File.txt):

digraph G {
...
1 [shape="oval" label= "Open"]  
8->9 [style="dashed" label= "true"]
...
}

I tried using sort -u File1.txt >> File.txt but I don’t want it sorted, I need it in the original order.

Thanks in advance

You can do this without sorting with AWK:

awk '!x[$0]++' file > newfile
