Version 0.2
usage: ./split_file.sh inf [chunk_size]
Default for chunk_size, which is in megabytes, is 1024 MB (1GB).
.tar.gz format).tar.gz format)To install from the Base64-encoded file, download the file as text and prepare cut and paste it into a terminal such as PuTTY logged into your desired host. Then run these commands, and make sure when cutting and pasting or retyping that any " character is not changed into a “ or a ” character.
cat > split_file-0.2.tar.gz.base64.txt
Paste into the window the contents of split_file-0.2.tar.gz.base64.txt, press Ctrl+D and press Enter, then retype or cut and paste these commands:
da=$(printf \\055) file=split_file$da""0.2 t=.tar.gz b=base64
openssl $b $da""d<"$file"$t.$b.txt>"$file"$t&&
tar xzvf "$file"$t&&
openssl dgst $da""sha256 "$file"{$t,$t.$b.txt,/s*,/t*}|tee sums.txt&&
(cd "$file"&&./t*)
If everything worked, it should say “Tests for split_file.sh passed.”
The sums above should exactly match what is in the split_file-0.2.sums.txt file. You can compare it with this command and then cutting and pasting that file, pressing Ctrl+D, and pressing Enter:
diff sums.txt $da&&echo Checksums all match.
You can now use the utility in split_file-0.2/split_file.sh. To have it easily available, copy it to /usr/local/bin:
install -m 755 split_file-0.2/split_file.sh /usr/local/bin
da=$(printf \\055) f=split_file$da""0.2 t=.tar.gz b=base64
