redirect output to a file name
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 lot!

To create a filename with the output
Code:
cat >`cat file1 | grep this`

To open a file, from a file, where file-name1 contains the file to be opened.

Code:
for i in <file-name1>
do
cat $i
done


Choose your method.

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
command > $name.txt

Data is stored in this file, cuz I'm able to do:

cat $name.txt but it doesn't appear on the folder. Any Idea why does it happen?

Do the following:

Code:
[nua7]: name=`awk '{print $2}' file1`
[nua7]: echo $name
089E
[nua7]: pwd >$name.txt
[nua7]: ls
089E  089E.txt  file1  file2  file3  mpstat.out
[nua7]: cat 089E.txt
/home/nua7

Also as a bit of explanation, awk's variables are entirely separate from the shell's variables. The traditional way to export a result from awk (or, indeed, any subprocess) to the current shell is with backticks, just like nua07 showed you already.

Code:
name=`awk '/Filename/ { print $2 }' File1`

Ok thanks, it works!!

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?

Thanks
