Shell Programming and Scripting

Hey Nixnoob,

it's not working.
And you're not supposed to put -u and -d at the same time, it's sort of a rule.

and I tried everything you said...

more didn't work, but what's the difference between more and cat?

btw, before I replaced the cat with the more:

sort -n -r -k2 -k1 file1 | uniq -u -d > file2
cat file2

It didn't print out anything, as if file2 was empty...

Yeah, it's not supposed to even be necessary...-u and -d are the defaults if you just execute uniq.



More just prints the output 1 page at a time where cat prints every thing to the output at once. I was thinking maybe cat was doing something it shouldn't be...it was just a random thought.

If you do an ls -la on file2 it will probably show the size as zero...that means the command errored and didn't actually create a readable file.

Now I'm just puzzled...I tried your original script and my way on a newly imaged HP-UX 11.23 server and I got the exact output I wanted.


*EDIT* Shira, as System Shock suggests, could you post the entire script as it is on your system?

This thread is going to go on forever with everyone trying to guess what's wrong until someone somehow hits it by chance. As shown in my last post, the syntax works.

My last suggestion is to post the entire script here and the location of all files including paths.

Happy hunting... I'm out.

OK, I fixed it!

It wasn't a syntax problem.

This is what I did:
I have a main script which creates a file. This file needs to create another file which is being "built" in a secondary script.

What I did, is that I wrote the "cat" part in the secondary script, and it didn't work, because the file was still in the making process.

Of course that I needed to cat, sort and uniq the file in the main script, and over there to create "temp" which is my final output file.
This is why the cat command worked so well in the command line - because it printed out "temp" after all the process, whilst the cat command in the secondary script printed "temp" in the middle of the making.

I thank you both for your patience - System_Shock, you were really close! , and nixnoob - you're awfully nice, I'm sorry I puzzled you.
Joey - I'm sorry I puzzled you as well.

Way to go girl...figuring it out on your own makes it a lot sweeter in the end.

You don't need uniq as well as sort; use the -u option:

Code:

sort -u -n -r -k 2 -k 1 file1 > file2

Perhaps because you sorted a different file?

You sent the ouput to temp, but you printed file2.

Hi cfajohnson,

it was a typo, I cleared it out in the beginning of thread.
Anyway, I already fixed that problem, I blamed cat for nothing.
The problem was that I should've written this segment in my main script, instead of the secondary script.

Thanks for the help though!
