-   -pipe: wyślij wyjście do WeeChat/wtyczki (linia po linii); jeśli występują spacje w komendzie/argumentach, otocz je cudzysłowem; zmienna $line jest zastępowana przez linie (domyślnie linia jest dodawana za komendą, oddzielona spacją) (nie kompatybilne z opcjami -bg/-o/-oc/-n/-nf)
--hsignal: wyślij wyjście jako hsignal (w celu użycia na przykład w triggerze) (nie kompatybilne z opcjami -bg/-o/-oc/-n/-nf)
- komenda: komenda do wykonania; jeśli zaczyna się od "url:", powłoka jest wyłączana i zawartość URLa jest pobierana i wysyłana jako wyjście
-      id: identyfikator komendy: numer lub nazwa (jeśli ustawiona przez "-name xxx")
-     -in: wyślij tekst na standardowe wejście procesu
--inclose: to samo co -in, ale stdin jest zamykane (tekst jest opcjonalny: bez niego stdin jest po prostu zamykane)
- -signal: wysyła sygnał do procesu; sygnał może być liczbą całkowitą lub jedna z nazw: hup, int, quit, kill, term, usr1, usr2
-   -kill: alias dla "-signal <id> kill"
--killall: zabija wszystkie działające procesy
-    -set: ustawia przypisaną właściwość (zobacz funkcję hook_set w opisie API wtyczek)
-właściwość: przypisana właściwość
-   wartość: nowa wartość

-    -all: usuń wszystkie zakończone komendy

-Domyślne opcje mogą być ustawione za pomocą opcji exec.command.default_options.
+   -list: list commands
+     -sh: use the shell to execute the command, many commands can be piped (WARNING: use this option ONLY if all arguments are safe, see option -nosh)
+   -nosh: do not use the shell to execute the command (required if the command has some unsafe data, for example the content of a message from another user) (default)
+     -bg: run process in background: do not display process output neither return code (not compatible with options -o/-oc/-n/-nf/-pipe/-hsignal)
+   -nobg: catch process output and display return code (default)
+  -stdin: create a pipe for sending data to the process (with /exec -in/-inclose)
+-nostdin: do not create a pipe for stdin (default)
+ -buffer: display/send output of command on this buffer (if the buffer is not found, a new buffer with name "exec.exec.xxx" is created)
+      -l: display locally output of command on buffer (default)
+      -o: send output of command to the buffer without executing commands (not compatible with options -bg/-pipe/-hsignal)
+     -oc: send output of command to the buffer and execute commands (lines starting with "/" or another custom command char) (not compatible with options -bg/-pipe/-hsignal)
+      -n: display output of command in a new buffer (not compatible with options -bg/-pipe/-hsignal)
+     -nf: display output of command in a new buffer with free content (no word-wrap, no limit on number of lines) (not compatible with options -bg/-pipe/-hsignal)
+   -oerr: also send stderr (error output) to the buffer (can be used only with options -o and -oc)
+     -cl: clear the new buffer before displaying output
+   -nocl: append to the new buffer without clear (default)
+     -sw: switch to the output buffer (default)
+   -nosw: don't switch to the output buffer
+     -ln: display line numbers (default in new buffer only)
+   -noln: don't display line numbers
+  -flush: display output of command in real time (default)
+-noflush: display output of command after its end
+  -color: action on ANSI colors in output:
+             ansi: keep ANSI codes as-is
+             auto: convert ANSI colors to WeeChat/IRC (default)

+          weechat: convert ANSI colors to WeeChat colors
+            strip: remove ANSI colors
+     -rc: display return code (default)
+   -norc: don't display return code
+-timeout: set a timeout for the command (in seconds)
+   -name: set a name for the command (to name it later with /exec)
+   -pipe: send the output to a WeeChat/plugin command (line by line); if there are spaces in command/arguments, enclose them with double quotes; variable $line is replaced by the line (by default the line is added after the command, separated by a space) (not compatible with options -bg/-o/-oc/-n/-nf)
+-hsignal: send the output as a hsignal (to be used for example in a trigger) (not compatible with options -bg/-o/-oc/-n/-nf)
+ command: the command to execute; if beginning with "url:", the shell is disabled and the content of URL is downloaded and sent as output
+      id: command identifier: either its number or name (if set with "-name xxx")
+     -in: send text on standard input of process
+-inclose: same as -in, but stdin is closed after (and text is optional: without text, the stdin is just closed)
+ -signal: send a signal to the process; the signal can be an integer or one of these names: hup, int, quit, kill, term, usr1, usr2
+   -kill: alias of "-signal <id> kill"
+-killall: kill all running processes
