$1 or ${1} refers to the first argument passed to the script when invoked.
If you have an script named myscript.sh and you invoked it as ./myscript.sh /dir1 /dir2, $1 for it will be /dir1 and $2 will be /dir2
In order to answer your question you need to tell us what arguments are passed to it when invoked.

VIFM(1) File Manager VIFM(1)
NAME
vifm - a ncurses based file manager with vi like keybindings
SYNOPSIS
vifm [ options ] [ dir1 [ dir2 ]]
DESCRIPTION
This manual page documents briefly the vifm file manager. This manual page was written for the Debian distribution because the original
program does not have a manual page.
vifm is a ncurses based file manager with vi like keybindings. If you use vi, vifm gives you complete keyboard control over your files
without having to learn a new set of commands.
For full documentation, visit the doc directory. A better man page may follow later.
OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is
included below.
The optional argument dir1 opens an initial directory in the left pane, the dir2 another one for the right pane respectively. If one or
both are missing, the current working directory is used.
--help Show summary of options.
--version
Show version of program.
