Redirect stdin stdout to multiple files
Hi,
i know how to
a) redirect stdout and stderr to one file,
b) and write to two files concurrently with same output using tee command
Now, i want to do both the above together.
I have a script and it should write both stdout and stderr in one file and also write the same content to another file at the same time.
In other words, both files should contain all stdout and stderr and both files
should be identical, and both files should overwrite any existing files
s1.sh > log1.txt 2>&1
In the above command i want to write the exact ouput to log2.txt at the same time
How to do this?
Thanks

I have tried this approach:
# ./script -option <argument1> <argument2> 0<$2
# $2: ambiguous redirect
Is this possible? (4 Replies)

Hi,
Program A: uses pipe()
I am able to read the stdout of PROGAM B (stdout got through system() command) into PROGRAM A using:
* child
-> dup2(fd, STDOUT_FILENO);
-> execl("/path/PROGRAM B", "PROGRAM B", NULL);
* parent
-> char line;
-> read(fd, line, 100);

All,
Ok...so I know I *should* be able to control a process's stdin and stdout from the parent by creating pipes and then dup'ing them in the child. And, this works with all "normal" programs that I've tried. Unfortunately, I want to intercept the stdin/out of the scp application and it seems... (9 Replies)
