Convert m4a to mp3
Damn my iPod doesn’t support m4a audio files ( http://support.apple.com/kb/sp27 )
No problem:
sudo apt-get install faad#!/bin/bash
IFS =$'\t\n'
EXTS =( m4a M4A m4A M4a )
for EXT in ${EXTS[@]} ;
do
for f in ` find . -name "*.$EXT " -type f` ;
do
echo "Converting m4a to mp3 ..."
faad -o - "$f " | lame - "${f%.m4a} .mp3"
rm $f
done
done Yes the script is similar to this resize multiple images
Great tool to edit tags (http://easytag.sourceforge.net/ )

Easy Backup Data Unix-Like
Some examples tested on Debian / Ubuntu
# Include .hidden_files (.svn/.git/etc...)
# copy dir on localhost
cp -a $SOME_PATH $NEW_PATH
# apt-get install smbfs smbclient
# Samba remote to local
smbclient "//SOME_PLACE/SHARED FOLDER" -U $USER $PASS -c \
"cd \" $SOME_PATH \" ; lcd \" $NEW_PATH \" ; prompt; recurse; mget *; quit"
# wget -c "http://ossw.ibcl.at/FTPSync/ftpsync-latest.tar.bz2"
# User and Password on .netrc (chmod 600) [http://www.mavetju.org/unix/netrc.php]
# FTP remote to local
ftpsync -gv ftpserver =someserver.com BackupWWW/ ftpdir =/ www/
# SSH Copy File
scp $SOME_FILE $USER @ $REMOTE :$SOME_PATH
# SSH Copy Dir
scp -r $SOME_PATH $USER @ $REMOTE :$SOME_PATH
# apt-get install rsync
# Sync directories
rsync -v -u -a --delete --stats $SOME_PATH $BACKUP_PATH
# Backup System:
nc -lp $HOST > backup.tar.gz
tar cf - $DIR | gzip | nc -w 1 $HOST $PORT
# Clone disk to other disk (same host)
dd if / dev/ sdX of =$OUTPUT # (OUTPUT could be /dev/sdY or /some/path/disk.img)
# Clonning Hard Drive (other host)
nc -l -p $PORT | dd of =/ dev/ sda
dd if / dev/ sda | nc $HOST $PORT
# Date
NOW =` date +% h-% d-% Y-% H% M% S`
# Compress (z = gzip or j = bzip2)
tar cvzf $BACKUP_FILE -$NOW .tar.gz $SOME_PATH
# MySQL
mysqldump $DB -u $USER --password =$PASS | gzip -c > $DB -$NOW .sql.gz
# SQLite
echo '.dump' | sqlite3 $DB | gzip -c > $DB -$NOW .sql.gz
# PostgreSQL
# .pgpass (chmod 600)
pg_dump $DB | gzip -c > $DB -$NOW .sql.gzUsing crontab to run your backup(s) script(s)
