However, there is a very good Bash script out there for converting various sound files to flac: https://www.legroom.net/software/convtoflac
I suggest you download it and study it. It's safe to use, by the way: I use it almost daily.

#
# App Title: convtoflac.sh
# App Version: 2.1.5
# Author: Jared Breland <jbreland@legroom.net>
# Homepage: http://www.legroom.net/software
#
# Script Function:
# Convert losslessly compressed audio file to FLAC format, preserving tags
# Currently supports FLAC, Monkey's Audio (APE), Shorten, WAV, and WavPack
#
# Instructions:
# Ensure that all programs are properly set in "Setup environment"
#
# Caveats:
# Transcoded files will retain original file name, but use .flac extension
# The one exception is for FLAC input files - the original input file will
# be renamed <name>_old.flac, and the transcoded file will be named
# <name>.flac.
#
# Requirements:
# The following programs must be installed and available
# sed (http://sed.sourceforge.net/)
# used to handle case sensitivity and tag processing
# trash-cli (http://code.google.com/p/trash-cli/))
# used for moving files to trash rather than deleting
# flac/metaflac (http://flac.sourceforge.net/)
# used to create and tag new FLAC files
# alac (http://craz.net/programs/itunes/alac.html)
# used to decompress ALAC (Apple Lossles) files
# mp4info, part of libmp4v2 (http://resare.com/libmp4v2/)
# used to read tags from ALAC (Apple Lossles) files
# mac (http://sourceforge.net/projects/mac-port/)
# used to decompress APE (Monkey's Audio) files
# apeinfo (http://www.legroom.net/software)
# used to read tags from APE files
# shorten (http://etree.org/shnutils/shorten/)
# used to decompress Shorten files
# ttaenc (http://www.true-audio.com/)
# used to decompress TTA (True Audio) files
# wvunpack (http://www.wavpack.com/)
# used to decompress WavPack files
# ffmpeg (http://www.ffmpeg.org/)
# used to decompress MLP, TAK, and lossles WMA files
# optionally used to decompress ALAC, APE, Shorten, and WavPack files
#
# Please visit the application's homepage for additional information.
