Split large files into files with .001 .002 (and so on) extension in CentOS via Terminal

Question

How to split large files into parts with .001 .002 (and so on) extension in CentOS via SSH Terminal (using Putty)?

For example, if I have a large file - LargeFile.iso, then how can I be able to split it into files like LargeFile.iso.001, LargeFile.iso.002, LargeFile.iso.003, LargeFile.iso.004.... and so on till LargeFile.iso.xxx (where xxx is the last part)?

Answer 1

Split is your friend with options:

-d --numeric-suffix  for numerical suffixes
-a -- suffix-lenght  for suffix lenght

Give a look at

split --help

in terminal

Answer 2

The best way might be a short bash script along the lines of

#!/bin/bash

BS=1024
SEGMENT=100000

LEN=$(ls -l | awk '{ print $5; }')
BL=$(($LEN/$BS))
S=0
I=1
while test "$BL" -le "$S"; do
  dd if="$1" of="$1."$(printf '%03d' $I) bs="$BS" skip="$S" count="$SEGMENT" 2>/dev/null
  S=$(($s+$SEGMENT))
  I=$(($I+1))
done
