Sourceval ls : string -> cmd

Sourceval sh : string -> cmd

Sourceval rg : ?in_:string -> string -> cmd

in_ is the directory that should be rg'd: rg <search> <in>. Without it, it'll filter stdin, just rg <search>

Sourceval rg_v : ?in_:string -> string -> cmd

Source

val find : 
  ?include_starting_dir:bool ->
  ?ignore_hidden:bool ->
  ?kind:[ `Files | `Directories ] ->
  ?name:string ->
  ?depth:int ->
  string ->
  cmd

Sourceval tr : string -> string -> cmd

Sourceval tr_d : string -> cmd

Sourceval grep : ?in_:string -> string -> cmd

Sourceval mkdir : string -> cmd

Sourceval mkdir_p : string -> cmd

Sourceval pwd : cmd

Sourceval less : cmd

Sourceval sort : cmd

Sourceval uniq : cmd

Sourceval shuf : cmd

Sourceval head : ?file:string -> int -> cmd

Sourceval tail : ?file:string -> int -> cmd

Sourceval tail_f : string -> cmd

Sourceval cp : string -> string -> cmd

Sourceval cp_r : string -> string -> cmd

Sourceval mv : string -> string -> cmd

Sourceval sed : ?g:bool -> string -> string -> cmd

Sourceval cut : ?d:char -> int -> cmd

Sourceval cut' : ?complement:unit -> ?d:char -> int list -> cmd

Sourceval (|.) : cmd -> cmd -> cmd

Source

val collect_lines : 
  ?cwd:string ->
  ?env:(string * string) list ->
  cmd ->
  string list

Source

val collect_stdout : 
  ?cwd:string ->
  ?env:(string * string) list ->
  cmd ->
  string

Sourceval map_lines : f:(string -> string) -> cmd

Sourceval filter_lines : f:(string -> bool) -> cmd

map within a series of pipes will be run in a thread.

Sourceval run : ?cwd:string -> ?env:(string * string) list -> cmd -> unit

Sourceval run_bg : ?cwd:string -> ?env:(string * string) list -> cmd -> unit

Run the process in a thread. Use wait to ensure that the parent won't exit, subsequently killing the background process.

Sourceval write_stdout_to : string -> cmd -> cmd

Sourceval append_stdout_to : string -> cmd -> cmd

Sourceval write_stderr_to : string -> cmd -> cmd

Sourceval append_stderr_to : string -> cmd -> cmd

Sourcemodule File_redirection_infix : sig ... end

Sourceval stdout_to_stderr : cmd -> cmd

Sourceval stderr_to_stdout : cmd -> cmd

stdout_to_stderr and stderr_to_stdout are NOT composable! Think of these functions as each creating a new command with the given redirection.

Applying both will result in no output to either stdout or stderr. flip_stdout_and_stderr should be easy to write if anyone should need it.

Sourceval devnull : string

devnull is easier to type than "/dev/null"

Sourceval last_exit : unit -> int

last_exit returns the exit status of the last child process to have exited

Sourceval fzf : ?cwd:string -> ?env:(string * string) list -> cmd -> string option

fzf runs the command, and fuzzy finds the stdout. Returns None if no item was chosen, Some str otherwise

Note that fzf is a way to to run a cmd and does not in itself return a cmd.

Sourceval debug : bool Core.ref
