Unix shell scripts are interpreted by a program, typically either a command shell (C-shell, bash, sh, tcsh, etc.) or by a scripting language program (perl, python, ruby, etc.)
For a shell script to be "executed" from a shell's command line, the shell script needs to have the execute bit set (see man page for chmod(1)) and the first line in the script will be in the form of: #!/bin/sh The important thing is the "#!" token which tells the shell which interpreter is appropriate for executing the script; in the example above, the intepreter is /bin/sh. So, in answer to your question, your C program should optionally check for the execute bit, fopen() the file and perform a fgets() to read a line, the C program should then parse the line to make sure that it conforms to the "#!" convention. If it finds a path to an interpreter, then your C program will probably need to fork() itself, and then use one of the exec() variants, passing it the file path to the interpreter as the name of the program to execute, and also handing it the path to the script as a "command-line" argument. Read the man pages for the particular interpreter to determine if there are any special switches that will have to be passed in order to introduce a script name for the interpreter to automatically run and exit instead of going into interactive mode. If any such switches are needed, you will have to pack it into the exec() call as well. -----Original Message----- Sent: Wednesday, October 22, 2003 11:45 AM To: Multiple recipients of list ORACLE-L The unix and C forums are pretty inactive.
