Hi all,

I don't know how to redirect a variable in this case:

while true
do
./ready_data
...
done

ready_data should read a file looking for an ID, if this doesn't exist then...

Ok... it works!

and now... if I want to open this file in other function by

open (char *filename, int flags, int mode)

how can I do to recognize the $name variable inside the function?
...

Ok thanks, it works!!

Actually into the first file there is something like:
...
Filename 089E data...
...

And I want to redirect a command into 089E.txt

I have tried:

awk '/Filename/ {name=$2;}' File1...

Hi all!!

is possible to assign the output of some command to filename, i.e.

grep_output.txt

Otherwise, I want to open a new file which name is inside another, how can I do it?

Thanks a...

Ahhh... you mean fot Temperature and everything, hehe... sorting alphabetically is right. Thank you very much.

Can you explain me every step of the program?

Great! Now I have easier line identifier, but actually my final target is to get something like this:

4D5A:Temperature: 27,5 / 28 / 21,5
4D5A:Humidity: 40 / 41 / 43
4D5A:Dew Point: 23 / 21 / 20...

Please I need to rearrange data acquired by USB port from a sensor network. The information is mixed and I need to convert it into a kind of table. This is my input file:

Node 4D5A joined...

Sorry the input file was missed

awk '/ / { }' input.file > output.file

Try this if you want to get every number:

awk '/Jun/ {print $0}' > output.file

or if you want to get the total

awk '/Jun/ {sum+ = $0}
END {print "grand total is:" sum}'

Actually I don't know how can I write in a line of a file at the end of the line... like APPEND option of files.

I'm trying to implement the whole program by awk...

Thanks a lot!!!

Which is the best command(s) to arrange data of a file?

This is my example input file:

Tom ------
apples: 5
oranges: 7
pears: 10
apples: 2
oranges: 8
Jack ------
apples: 3
pears: 10...

Thanks, it works fine!!

Ok I have used it, but I think that my manner is not really elegant.

Do you know how to (by sed)...

overwrite a line which actually you only know how it begins but not how finishes?

I want...

no, I want to do it in a boot script.

I want to do it by commands lines.

Hi all,

I am trying to overwrite some lines of a very big file.
I know the number of the line but I don't know how to point the cursor on its beginning. there is an option to notice the offset in...

So... by closing stdout you are sending the output to nowhere. Is like that?

Thank you!

Hi!

I'm new in these forums and more or less new with Unix. So... here is the question:

does anyone know where is redirected the output of a command when you put >&- after it?

Does it means...
