[SOLVED] Sort file in bash shell

Issue

I want to sort file, by the first number, which looks like this.

11: wc 
1:cmp: 
115:wc
7:ls

So i get output in file like this.

1:cmp:
7:ls 
11: wc 
115:wc

I've tried to sort it my self, but it doesn't work. This is my following code

cat dat | sort -t ":" -k 1 >dat;

What can i do? Thank you!

Solution

You can use this sort command with numeric sort:

sort -t: -nk1 file
1:cmp:
7:ls
11: wc
115:wc
