For windows was pretty simple to redirect the std in a and out of a
child process for "cmd.exe " command prompt terminal to a socket using connected pipes passed to a new process in the STARTUPINFO structure.
In above code the context (current directory) of the terminal cmd.exe is not lost between connections, and I can run internal shell commands as start, call, cd, and so on ....
For Linux I've tried to mimic the shell using popen(), and to write and read in the handler returned by popen(), but I cannot run /bash shell commands as cd, cp, mkdir and so on because they are internal bin/bash commands. I would like to have a shell up, and to write and read from it trough it's stdin stdout, available in my app (pipes of file handlers).
Something like:
I tried these samples (but they don;t hold the shell up, and the command is sent to a shell, then the shell is closed):
My supervisor keep getting "stdin not tty" or something like that when he pipe or redirect input into a program. Others
don't seem to get this message. Is there some way I can help him to fix or turn this off?
Thx in advance (1 Reply)
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)

Looking for the proper way to bring a string into the stdin. I have a string that I would like to grep and awk. Each have to be run separately, not piped together. So far, the only way I could figure out how is to echo the string and pipe it:

Mail::SPF::Mod::Redirect(3) User Contributed Perl Documentation Mail::SPF::Mod::Redirect(3)NAME
Mail::SPF::Mod::Redirect - SPF record "redirect" modifier class
DESCRIPTION
An object of class Mail::SPF::Mod::Redirect represents an SPF record modifier of type "redirect".
Constructors
The following constructors are provided:
new(%options): returns Mail::SPF::Mod::Redirect
Creates a new SPF record "redirect" modifier object.
%options is a list of key/value pairs representing any of the following options:
domain_spec
See "new" in Mail::SPF::Mod.
new_from_string($text, %options): returns Mail::SPF::Mod::Redirect; throws Mail::SPF::ENothingToParse, Mail::SPF::EInvalidMod
Creates a new SPF record "redirect" modifier object by parsing the string and any options given.
Class methods
The following class methods are provided:
name: returns string
Returns 'redirect'.
name_pattern: returns Regexp
Returns a regular expression that matches a modifier name of 'redirect'.
precedence: returns real
Returns a precedence value of 0.8. See "precedence" in Mail::SPF::Mod.
Instance methods
The following instance methods are provided:
params
See "params" in Mail::SPF::Mod.
domain_spec: returns Mail::SPF::MacroString
Returns the "domain-spec" parameter of the modifier.
process($server, $request, $result): throws Mail::SPF::Result
If no mechanism matched during the evaluation of the current SPF record, performs a recursive SPF check using the given SPF server and
request objects and substituting the modifier's target domain name for the request's authority domain. The result of the recursive SPF
check is then thrown as the result of the current record's evaluation. However, if the target domain has no acceptable SPF record, a
"permerror" result is thrown. See RFC 4408, 6.1, for details.
See Mail::SPF::Mod for other supported instance methods.
