HP-UX 11.0 N4000 I have two different file sizes for the POSIX shell. The one root is mapped to and the one general users are mapped to are different sizes.

What is the command to set a path to an executable/binary file and its corresponding library in .sh file The default path is '/usr/sbin:/bin:/usr/bin:'. If the command name contains a / then the search path is not used. Otherwise, each directory in the path is searched for an executable file. If the file has execute permission but is not an a.out file, it is assumed to be a file containing shell commands. A subshell (i.e., a separate process) is spawned to read it. I have figured out the address of the system() using p system command in gdb. And by inspection of the stack frame using x/500s $esp, I figured the environment variable's address which contains \bin\sh.

The Bourne shell was the default shell for Version 7 Unix. Unix-like systems continue to have /bin/sh—which will be the Bourne shell, or a symbolic link or hard link to a compatible shell—even when other shells are used by most users.
