sort command - alphanumeric
I have a file I'm trying to sort such as

fred1
fred2
fred10
fred11
...

when I sort I get

fred1
fred10
fred11
fred2
...

using sort can any give me the syntax to sort this is dict order

e.g.,

fred1
fred2
fred10
fred11

I've done is in the past but can't for the life of me remember the syntax!

If they all actually begin with "fred":
Code:
echo "fred1
fred2
fred10
fred11" | sort -k1.5n

Yields
Code:
fred1
fred2
fred10
fred11

Glenn,

Can you please tell what does sort -k1.5n mean? I think you are specifying the key as fred but what does -k.5n signify?

Let's see if I can explain this correctly (I'm still working on my sort skills):

-k to set the key
1.5 means that the 5th character of the 1st field is the start of the sort field
n means that this field is to be treated as numeric

Anyone else feel free to correct that explanation if it's not accurate.
