I want to see what shell command line were used to start Vim. For example, I used command

vim -S Session.vim

argv() and argc() don't show switches and it's parameters.

Command

:echo tr(join(readfile("/proc/" . getpid() . "/cmdline")), "\n", " ")

shows command line. But, is there more elegant (shorter) method?

You can use the special v: variable v:argv, which would show, when running vim -S Session.vim exactly this:

:echo v:argv
['vim', '-S', 'Session.vim']

In addition, to get the proper vim binary, you should probably also use the v:progpath variable, which specifies the exact path of the vim binary that was run (which matters if you have several vim binaries installed, because e.g. you compile your own version)

  • There is no v:argv in Vim 7.4 that I use. But thanks for hint.

  • I do to. But still you wouldn't get all the security updates and some of the core vim feature enhancements

  • I'm inspired Your problem with Vim.... And Vim 7.4 never sum up me on 2 machines: Linux 2.6 and Cygwin. New features are OK. But for me 7.4 is enough.
