Module summary
Operating system-specific functions.
Description
The functions in this module are operating system-specific. Careless use of these functions results in programs that will only run on a specific platform. On the other hand, with careful use, these functions can be of help in enabling a program to run on most platforms.
Exports
cmd(Command) -> string()
Types:
Command = atom() | io_lib:chars()
Executes Command in a command shell of the target OS, captures the standard output of the command, and returns this result as a string. This function is a replacement of the previous function unix:cmd/1; they are equivalent on a Unix platform.
Examples:
LsOut = os:cmd("ls"), % on unix platform
