I figured the files were just literally split and renamed, just shows how stupid people are that try to make you download this closed source HJSplit crap probably full of virii. Shh, don’t show them this page or they will insert headers and obfuscation in the split files!

thanks a million. i honestly feel “enlightened” this is a really neat feature that i can use. i was not aware of the split command and the script makes sense (to me) now.

@aman: that’s easy. to split the file use bash’s split command.

split -da 3 bigfile.pdf splitfiles

(‘man split’ for more info on the useful split command)

the command:

i=1;for file in splitfiles*; do mv $file $(printf “newfiles.%03i” $i);i=$((i+1)) ; done

is just used to rename the files so the first splitfile has .001 has its extension instead of .000 which is the default for the split command.

Because HJSplit only detect files starting with .*1 as its first file (which is weird in computerland where everything should start with 0).

I guess you can make a better version using Perl/Python/Ruby/etc that will split files into HJSPlit named formats but I’m lazy so the above will work anytime, everytime without you breaking a sweat.

great tip. i rate this as one from a “guru”. thanks. but i can not figure out the script that would split the file. where are we specifying the number of parts we would like to split the file into ?

You have the choice of installing cygwin.com. But why install cygwin when you can install hjsplit for windows.

This is just for linux users who don’t want to install hjsplit for linux on their machines.

You can try the “type” command in the command propt but I’m not sure if that will work.

We’d like to hear if you are successful.
