Hello Group,

I want to ask ,how we can use shell commands like 'sed' and many
others in Lua program.
Direct syntax of sed is not working.

I got the following error:

lua: part.lua:23: attempt to call global 'sed' (a nil value)
stack traceback:
	part.lua:23: in main chunk
	[C]: in ?

I searched internet but didnt find anything relevant.
Any help would be appreciated.
