How do I split the output from mysqldump into smaller files?

This bash script splits a dumpfile of one database into separate files for each table and names with csplit and names them accordingly:

#!/bin/bash

####
# Split MySQL dump SQL file into one file per table
# based on https://gist.github.com/jasny/1608062
####

#adjust this to your case:
START="/-- Table structure for table/"
# or 
#START="/DROP TABLE IF EXISTS/"


if [ $# -lt 1 ] || [[ $1 == "--help" ]] || [[ $1 == "-h" ]] ; then
        echo "USAGE: extract all tables:"
        echo " $0 DUMP_FILE"
        echo "extract one table:"
        echo " $0 DUMP_FILE [TABLE]"
        exit
fi

if [ $# -ge 2 ] ; then
        #extract one table $2
        csplit -s -ftable $1 "/-- Table structure for table/" "%-- Table structure for table \`$2\`%" "/-- Table structure for table/" "%40103 SET TIME_ZONE=@OLD_TIME_ZONE%1"
else
        #extract all tables
        csplit -s -ftable $1 "$START" {*}
fi
 
[ $? -eq 0 ] || exit
 
mv table00 head
 
FILE=`ls -1 table* | tail -n 1`
if [ $# -ge 2 ] ; then
        # cut off all other tables
        mv $FILE foot
else
        # cut off the end of each file
        csplit -b '%d' -s -f$FILE $FILE "/40103 SET TIME_ZONE=@OLD_TIME_ZONE/" {*}
        mv ${FILE}1 foot
fi
 
for FILE in `ls -1 table*`; do
        NAME=`head -n1 $FILE | cut -d$'\x60' -f2`
        cat head $FILE foot > "$NAME.sql"
done
 
rm head foot table*

First dump the schema (it surely fits in 2Mb, no?)

mysqldump -d --all-databases 

and restore it.

Afterwards dump only the data in separate insert statements, so you can split the files and restore them without having to concatenate them on the remote server

mysqldump --all-databases --extended-insert=FALSE --no-create-info=TRUE
