Dear All,
Good day. Here i am facing some problem like below.
file contains
12345 0001 090112
14385 0001 090112
13255 0001 090112
11345 0001 090112
....

I want to sort ascending according to the first column. What will be the shell script.

12345 0001 090112
14385 0001 090112
13255 0001 090112
11345 0001 090112

sort sortfile

11345 0001 090112
12345 0001 090112
13255 0001 090112
