Calling shell script from a C program
 

hi,
im COMPLETELY new to linux. using it for the first time. i need to learn how to call a shell script from a c program. the script im using is

#!/bin/bash
# first script
who am i
date
pwd

how do i call it in a c program using 'system'.

Thanks.

Not sure what/why you're asking...you seem to answer your own question. You call it using the 'system' function, like you said. Doing it on Linux is no different than calling a program on Windows or Mac in C.

Im asking what arguments system() takes? im providing the path of the script file but it doesnt work.

the shell script runs fine. the c program compiles. but when i run it it gives me error

sh:1 home/user/documents/firstshell.sh not found.

Could you guide me where i could be wrong?

Thanks, it was just a syntax error :)

I'm guessing that you forgot the leading slash before "home" -- am I right?

Note that if you want to be able to actually use the output of the script in the program, you'll need to use something like popen to do so.
