.SH NAME
sfm \- Simple File Manager

.SH SYNOPSIS
.B sfm
.RI [ path ]

.SH DESCRIPTION
.B sfm
is a lightweight, terminal-based file manager written entirely in POSIX sh.
It runs in your terminal with no external dependencies beyond standard Unix
tools. Designed to be fast, flicker-free, and keyboard-driven with a
vim-inspired key layout.

If
.I path
is given, sfm opens that directory. Otherwise it opens in the current
working directory.

.SH CUSTOM OPENER
.B sfm
checks for a user-defined opener script at:
.PP
.I ~/.config/sfm/opener
.PP
If the file exists and is executable, sfm passes the selected file path
to it as the first argument instead of using the built-in smart opener.
.PP
Example opener script:
.PP
.nf
#!/bin/sh
case "$1" in
    *.jpg|*.jpeg) imv "$1" ;;
    *.mp4)        mpv "$1" ;;
    *.html|*.pdf) firefox "$1" ;;
    *)            echo "no program set for this file type" ;;
esac
.fi
.PP
Make it executable with:
.B chmod +x ~/.config/sfm/opener
.PP
If the opener script does not exist, sfm falls back to its built-in
smart opener which detects file types by extension and MIME type.
