I am using pipes (specifically piping out) in Perl to put an array from one file into an array in a different file. I can't figure out how to transfer the array. I kow how to open the pipe : open (FILEHANDLE, "| file") or die~
but how do I transfer the array. I think it has something to do with... (1 Reply)
Hi, I am trying to write a program that will pipe any number of programs together like in the linux shell. As an example, the below code tries to execute "cat data | grep int | cut -b 1-10." The problem is that the programs never get executed for some reason. It seems like the first program... (3 Replies)
I've got a file with lots of commands I want to run in it. They're formatted like so:
cp /path/to/file /path/to/new/file
and on and on and on.
Hundreds of them.
Anyways, I'd like to execute them one at a time, then check what time it is, and repeat this process until 7am.
I can... (3 Replies)
Hi,
To explain this question I will have to go into a bit of detail. I hope you don't mind.
currently I have a log handler (an already compiled c++ version) and what it does is makes a log file and writes all the unix output (echo, etc) of a script to that log file. To me the log_handler is... (3 Replies)
Hi,
I'm trying to wrap my head around piping in C - I've got a small C program that forks and pipes stuff from the child process to the parent process.
Currently the child process calls a C program that squirts out random numbers which then pipes the result to the parent process.
The... (0 Replies)
Hi,
I need to use a double grep so to speak. I need to grep for a particular item say BOB and then for each successful result I need to grep for another item say SMITH.
I tried grep "BOB" filename | grep "SMITH"
but it does not seem to work.
I can achieve my desired result using an... (12 Replies)
Hi everybody,
I have a big file with blast results (if you know what this means, otherwise look at it just as a text file with a specific form).
I am trying to extract some ids from within this file, which have certain parameters.
For example, some Of my IDs have the term 'No hit results'... (1 Reply)
Hi ,

Hey guys. I'm very new to Unix. I'm pretty fluent in Java and C, but I have never actually used Unix for anything. I am in an Operating Systems course now and I have an assignment to write a piece of code that involves forks and piping. I'm stuck.
1. The problem statement, all variables and... (6 Replies)

standards - UNIX standards behavior on HP-UX
DESCRIPTION
HP-UX conforms to various UNIX standards. In some cases, these standards conflict. This manpage describes the methods that programmers
and users must follow to have an application conform and execute according to a particular UNIX standard.
UNIX Standard Conformant Programmer Environment
The following table lists feature test macros and environment variables that must be defined while compiling an application. Both a fea-
ture test macro and an environment variable must be defined while compiling the application so that the application conforms and executes
according to a particular UNIX standard. Otherwise, the behavior is undefined.
Standard Feature Test Macros to be Environment variable
defined during compilation to be set
UNIX 95 _XOPEN_SOURCE_EXTENDED=1 UNIX95 or
UNIX_STD=95 or
UNIX_STD=1995
UNIX 2003 _XOPEN_SOURCE=600 UNIX_STD=2003
The compiler uses the feature test macros to obtain the appropriate namespace from the header files. The compiler uses the environment
variable to link in an appropriate object file to the executable. Using the environment variable customizes libc to match UNIX standards
for various functions.
If an application has already been compiled for default HP-UX behavior or for one particular standard, and needs to change to a particular
UNIX standard behavior, recompile the application as specified in the above table.
For an HP-UX command to conform to a particular UNIX standard behavior, the application has to set the corresponding environment variable
as specified in the above table before executing that command.
UNIX Standard Conformant User Environment
To enable a particular UNIX standard conformant user environment, set the corresponding environment variable as defined in the above table.
EXAMPLES
The following examples shows an application example. To have the system be conformant to UNIX2003 behavior, set the environment variable
to and define the feature test macro before compilation.
The following example changes the command to have UNIX95 behavior by setting one of the environment variables to or to before executing
that command. There are three ways of setting the environment variable for UNIX95:
