Network awk doubt

I'm having a file with 5 fields.
I want to sort that file according to one field
no 3. How shall I do using awk programming.

Any input appreciatable.

If you are asking how to sort a file on the 5th field, that's easy:

sort -k 5 < file

I can certainly give you an example in awk too, but, be careful what you ask for.. ;-)

Sort is not reliable for all fields.


thanks for ur response. But that sort option is
not working. My file is like,

ABCD 2.03 0.00 123.00 0.00
ACB 0.00 25.00 0.00 123.23
ABVCERR[12] 0.00 456.00 98.00 0.00

like this I want to sort with the last field.
As every field is of various length and 5 spaces
between fields, I'm not able to use sort command
like sort -t\ +3rn < file
it is giving some garbage results. That's why
I want an awk program which will be a secured one.
Thanks for any input.

Try "sort -k5n". I have tried it on your data and it worked for me.

Remember, homework is not allowed in the forums. This looks like a homework problem to me Smilie

I'm not a student.


I'm a programmer. I'm having the problem in
extracting a report file. I dont want to give
the exact information in the report file,
so I gave an example. If it leads to a
misunderstanding that I'm a student I feel
sorry for that.

Hi Perderabo,

I'm getting error message like,

sort: option requires an argument -- k

for the command sort -k5n < file
It is suggesting that I've to give end
field argument also.
