Module `V1.Process`

Execute external programs.

type result = { exit_code : int; stdout : string; stderr : string; }

val run : t -> ?⁠dir:string -> ?⁠env:string list -> string -> string list -> result

run t prog args runs prog with arguments args and returns its exit status together with the content of stdout and stderr. The action is logged.

parameter dir: change to dir before running the command.

parameter env: specify additional environment variables as a list of the form NAME=VALUE.

val run_capture_exn : t -> ?⁠dir:string -> ?⁠env:string list -> string -> string list -> string: run_capture_exn t prog args same as run t prog args but returns stdout and die if the error code is nonzero or there is some output on stderr.

val run_ok : t -> ?⁠dir:string -> ?⁠env:string list -> string -> string list -> bool: run_ok t prog args same as run t prog args but only cares whether the execution terminated successfully (i.e., returned an error code of 0).
