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

can you redirect STDIN with command arguments?
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)

shmidcat
SHMIDCAT(1) Shared Memory Trampoline SHMIDCAT(1)
NAME
shmidcat - Copies stdin/file to a shared memory block for gtkwave(1)
SYNTAX
shmidcat [VCDFILE]
DESCRIPTION
Copies either the file specified at the command line or stdin (if no file specified) line by line to a shared memory block. stdout will
contain a shared memory ID which should be passed on to gtkwave(1).
EXAMPLES
To run this program the standard way type:
cat whatever.vcd | shmidcat
The shared memory ID is emitted to stdout.
shmidcat whatever.vcd | gtkwave -v -I whatever.sav
GTKWave directly grabs the ID from stdin.
LIMITATIONS
This program is mainly for illustrative and testing purposes only. Its primary use is for people who wish to write interactive VCD dumpers
for gtkwave(1) as its source code may be examined, particularly the emit_string() function. It can also be used to test if an existing VCD
file will load properly in interactive mode. Note that it can also be used to redirect VCD files which are written into a pipe to gtk-
wave(1) in a non-blocking fashion.
