My links:

Working:
[[elisp:(term "xterm")]]

**Not working**
[[elisp:(term "xterm visidata /tmp/foo.csv")]]
  1. [X] Open xterm from org mode link
  2. [ ] Open xterm from org mode link with arguments

How can I append arguments to the terminal command?

  • What about src_screen{echo "hello"} or src_bash{<something>}?

  • @mankoff I need a new frame/window opened with the cli-app launched. Offtopic: Searching emacs "src_screen" returned three (irrelevant) results :)

I don't think term does what you think it does: if you want to open an external xterm window running visidata /tmp/foo.csv, then you want to run the elisp expression:

(shell-command "xterm -e visidata /tmp/foo.csv &")

so your link should look like [[elisp:(shell-command "xterm -e visidata /tmp/foo.csv &")]].

EDIT: as the commenters indicate, the command needs to be run asynchronously, otherwise emacs waits for the command to finish and will not do anything else. That can be done, as the OP indicates in their comment, with start-process, but it can also be done, perhaps more simply, with shell-command, by adding an & at the end of the command (see the edited code above), which is how you run a shell command in the background. C-h f shell-command has all the details.

    Got infinite executing Emacs-Lisp code block.... Though you lead me to this working line: (start-process "" nil "/usr/bin/xterm" "-e" "visidata" "/tmp/foo.csv")

    I can confirm what @412p9wej mentioned: Using shell-command on an Org Mode link results in Emacs freezing, while using start-process does open a terminal window. I tried this with the following links: [[elisp:(shell-command "st")]] and [[elisp:(start-process "st" nil "st")]].
