Bulk conversion of mp3 files into flac files in Linux

Some times before converting mp3 files to flac files in batches in Linux, I forwarded a post about audio conversion. today, I am excited and want to convert all the mp3 files on the computer into flac files, follow the steps below: 1. straighten out the idea: it seems that mp3 cannot be directly converted to flac, so I... some times before converting mp3 files to flac files in batches in Linux, I forwarded a post about audio conversion. today, I am excited and want to convert all the mp3 files on the computer into flac files, the steps are as follows: 1. straighten out the idea: it seems that mp3 cannot be directly converted to flac, so I chose mp3 --> wav --> flac. 2. install the conversion software: mp3 --> wav requires lame software; # sudo apt-get install lamewav in ubuntu --> flac or shntool software is required for flac, # In ubuntu, sudo apt-get install flac shntool 3 can be used for batch conversion. Ll script is easier to implement :#! /Bin/sh for file in *. mp3; doif [-f "$ file"]; thenlame -- decode $ file $ {file/.mp32.16.wav; newfile =$ {file/.mp32.16.wav; shnconv-o flac $ newfile; # or flac-8 $ newfile; rm $ file $ newfile; else echo "no input file"; continue; fi done 4. Summary: I originally wanted to implement it in the command line, but it will never work.
