Instead of what?
I do not create or open a file. All I need is to get the answer of any command from the command line into a string, "pwd" is just an example.

Can you please give a simple example?

Situation: I have

char command[50] = "ls";

system(command); // executes the string

pwd(1)								   User Commands							    pwd(1)

NAME
pwd - return working directory name SYNOPSIS
/usr/bin/pwd DESCRIPTION
The pwd utility writes an absolute path name of the current working directory to standard output. Both the Bourne shell, sh(1), and the Korn shell, ksh(1), also have a built-in pwd command. ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of pwd: LANG, LC_ALL, LC_MESSAGES, and NLSPATH. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. If an error is detected, output will not be written to standard output, a diagnostic message will be written to standard error, and the exit status will not be 0. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |CSI |enabled | +-----------------------------+-----------------------------+ |Interface Stability |Standard | +-----------------------------+-----------------------------+ SEE ALSO
cd(1), ksh(1), sh(1), shell_builtins(1), attributes(5), environ(5), standards(5) DIAGNOSTICS
``Cannot open ..'' and ``Read error in ..'' indicate possible file system trouble and should be referred to a UNIX system administrator. NOTES
If you move the current directory or one above it, pwd may not give the correct response. Use the cd(1) command with a full path name to correct this situation. SunOS 5.10 28 Mar 1995 pwd(1)
