module POSIXShell: sig
.. end
val split : string -> string list
split s
: the string s
is interpreted as command line
arguments and splitted into its components (un-escaped). For
example split "a \"b c\" d" = ["a"; "b c"; "d"]
. Note that
split "" = []
. It is possible that substitutions such as "$a"
(resp. "$(a b)") may be transformed into "${a}" (resp. "${a b}").
val escape : string -> string
escape s
quote s
if needed to protect spaces, '"' and '\''
so it reads as a single argument in a POSIX shell command, the
content of which is identical to s
(interpreted with OCaml
conventions). If quoted, the returned string will start and end
with '"'. The original string s
is returned if no quoting is
necessary.
val unescape : string -> string
unescape s
returns a string s'
removing all backslashes
preceding a char.
