| − | <big>Simple ID3v1 Reader</big>
| + | Slam dunkin like Shaquille O'Neal, if he wrote informative atricles. |
| − | __TOC__
| + | |
| − | ==What is this?==
| + | |
| − | A simple and quick command line ID3v1 tag reader for getting artist, title, etc data from mp3s. Googling for a pre-existing one was taking too long so decided to write this one night. Most of the others had lots of excess features, like a GUI, pffft! Enjoy the redundancy! :P

| − | | + | |
| − | ==Examples==
| + | |
| − | '''Compile'''<br> | + | |
| − | This is obvious, just copy the code below to main.c and:
| + | |
| − | <source lang="bash">
| + | |
| − | gcc -o id3 main.c
| + | |
| − | </source>
| + | |
| − | | + | |
| − | '''Using'''<br>
| + | |
| − | <pre>
| + | |
| − | ~/Projects/mp3tagread$ ./id3 /media/160gb/e/MP3s/Dead\ Prez\ -\ Hip-Hop.mp3
| + | |
| − | title: Hip-Hop
| + | |
| − | artist: Dead Prez

| + | |
| − | | + | |
| − | '''Getting just one field'''
| + | |
| − | <pre>
| + | |
| − | ~/Projects/mp3tagread$ ./id3 /media/160gb/e/MP3s/Dead\ Prez\ -\ Hip-Hop.mp3 | grep "^title\:"
| + | |
| − | title: Hip-Hop
| + | |
| − | </pre>
| + | |
| − | | + | |
| − | '''Translating SJIS to UTF-8'''<br>
| + | |
| − | Requires the recode command, but can be used to translate id3 tags :D
| + | |
| − | <pre>
| + | |
| − | ~/Projects/mp3tagread$ ./id3 ~/Music/th03_├ª┬¥┬▒├ªΓÇô┬╣├Ñ┬ñ┬ó├ªΓäóΓÇÜ├º┬⌐┬║\ ├»┬╜┼╛\ Phantasmagoria\ \
