You put your dreasmwarrior key into the directory (.ssh) for the user you want to be. e.g., whoever.
then
Code:
ssh whoever@remotebox
#or
sftp whoever@anotherbox
You are now whoever, not dreamwarrior, on the remote box. So all you have to keep straight is what username goes with what remote box.
Ahh...well, that's the part that I wasn't getting. I didn't realize that would work. I'm an SA n00b for sure, lol! THANKS! I suppose the upfront work may be annoying, but at least it'll only have to be done once!
Much appreciated, and yes I agree, this is a much better solution than my hacking away supposing they'll let me do it. They may still say "well, if your dreamwarrior account gets hacked then the hacker has access to everything now...don't they." In which case, I suppose I can use the passphrase on the key and at least (according to Corona) I should only have to enter the passphrase once to enable the key and never again. Then there's another level of security.
Hello all, I am trying to create n child processes and control them from a parent process; say make child 3 print its pid and then child 5 do the same and some other stuff. Is there a way to accomplishing this after all the child processes are created via a call to fork().
Thank you,

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);

Hi all
I've run into a snag in a program of mine where part of what I entered in at the start of run-time, instead of the current value within printf() is being printed out.
After failing with fflush() and setbuf(), I tried the following approach

I am trying to implement the below using Ksh script on a Lx machine.
There is a file(input_file) with 100K records. For each of these records, certain script(process_rec) needs to be called with the record as input. Sequential processing is time-consuming and parallel processing would eat up... (2 Replies)

In my script i have 2 variables which can have value of 0 or 1.

filter_create_fd
filter_create_fd(3) util/filter.h filter_create_fd(3)NAME
filter_create_fd - Create a sub process and return the requested pipes
SYNOPSIS
#include <util/filter.h>
NEOERR *filter_create_fd(const char *cmd, int *fdin, int *fdout, int *fderr,
pid_t *pid);
ARGUMENTS
cmd -> the sub command to execute. Will be executed with
/bin/sh -c
fdin -> pointer to return the stdin pipe, or NULL if you don't
want the stdin pipe
fdout -> pointer to return the stdout pipe, or NULL if you don't
want the stdout pipe
fderr -> pointer to return the stderr pipe, or NULL if you don't
want the stderr pipe
DESCRIPTION
filter_create_fd and filter_create_fp are what popen
been: a mechanism to create sub processes and have pipes to all their input/output. The concept was taken from mutt, though python has
something similar with popen3/popen4. You control which pipes the function returns by the fdin/fdout/fderr arguments. A NULL value means
"don't create a pipe", a pointer to an int will cause the pipes to be created and the value of the file descriptor stored in the int. You
will have to close(2) the file descriptors yourself.
RETURN VALUE
fdin -> the stdin file descriptor of the sub process
fdout -> the stdout file descriptor of the sub process
fderr -> the stderr file descriptor of the sub process
pid -> the pid of the sub process
