Split big files in bash with … split

Example on how to use split to phisically split large files in smaller ones. 

ls -lh bigfile
# This is our initial situation: a large file we want to split
#-rw-r--r-- 1 foo foo 10M Jul 29 11:30 bigfile

# This will do the dirty job
# we're going to split the big file in many little ones, each of 2mb
split -b 2m bigfile part_

# Let's check what we got
ls -lh part_* 
# Will output the list of new files
#-rw-r--r-- 1 foo foo 2.0M Jul 29 11:31 part_aa
#-rw-r--r-- 1 foo foo 2.0M Jul 29 11:31 part_ab
#-rw-r--r-- 1 foo foo 2.0M Jul 29 11:31 part_ac
#-rw-r--r-- 1 foo foo 2.0M Jul 29 11:31 part_ad
#-rw-r--r-- 1 foo foo 2.0M Jul 29 11:31 part_ae
