Splitting and joining ISO image into smaller files for backup onto FAT32 drive

[success2be]

What commands do I use to split and join binary files? Please show me the usage of the commands too. Thanks. The 'man' command can be confusing.

 

I think I found 'split', but I'm not sure if 'cat' is what I use to join two binary files. I remembered using 'cat' to display text files to the screen.

use cat to join the iso segments.

 

cat isopart1.iso isopart2.iso > full.iso

use cat to join the iso segments.

 

cat isopart1.iso isopart2.iso > full.iso

 

Do u mind giving a step by step instruction?

 

i've tried this

 

cat "filename*" > "output file name"

or

cat "filenamea[a-e]" > "output filename"

 

but it just keep saying no such file exist

I assume you'd have to CD to the directory first so:

 

cd /directory/where/iso/parts/are/
cat part1.iso part2.iso > both_parts_combined.iso

 

Thats if you want to merge 2 parts of an ISO together.

This was what happenned when i tried to change directory

 

cjmclean$ cd/Documents/Movies/123/abc

-bash: cd/Documets/Movies/123/abc: No such file or directory

 

 

thanks for helping mate!

[chris2k]

a space was missing, do this:

 

cd /Users/cjmclean/Documents/Movies/123/abc

 

'cat' as described above

 

'split -b1024m <file>'

would split the file into 1024MB parts...

[CJMclean]

after i hit

 

cat "abc_a[a-b]" > "abc.iso"

 

nuthin happens

 

Sorry fellas, i'm such a noob

[chris2k]

cat part1 part2 part3 >full.iso

[CJMclean]
