Hi my database has started to go over 2GB in backed up size, so I'm looking at options for splitting the file and then reassembling it to restore the database.
I've got a series of files from doing the following backup shell file:
DATE_STRING=\date +%u%a\
BACKUP_DIR=/home/myhome/backups
/usr/local/mysql_versions/mysql-5.0.27/bin/mysqldump --defaults-file=/usr/local/mysql_versions/mysql-5.0.27/my.cnf --user=myuser --password=mypw --add-drop-table --single-transaction mydb | split -b 100000000 - rank-$DATE_STRING.sql-;
this prodes a sequence of files like:
mydb-3Wed.sql-aa
mydb-3Wed.sql-ab
mydb-3Wed.sql-ac
...
my question is what is the corresponding sequence of commands that I need to use for linux to do the restore?
Previously I was using this command:
/usr/local/mysql_versions/mysql-5.0.27/bin/mysql --defaults-file=/usr/local/mysql_versions/mysql-5.0.27/my.cnf --user=myuser --password=mypw -D mydb < the_old_big_dbdump.sql
Any suggestions even if they don't involve split / cat would be greatly appreciated

I don't see why you can't just do:
cat mydb-3Wed.sql-* | /usr/local/mysql_versions/mysql-5.0.27/bin/mysql --defaults-file=/usr/local/mysql_versions/mysql-5.0.27/my.cnf --user=myuser --password=mypw -D mydb
The * globbing should provide the files in the sorted order, check with ls mydb-3Wed.sql-* that they actually are though.
Eric M : Good to see proper basic shell knowledge applied.Simon B : Yup you're right, sorry for such a basic question. Thanks for replying, Simon B
