How to open a split zip archive with more than 99 parts?

I think the problem is that when I concatenate the zip files before unzipping they are not in order because zip only uses one leading zero. For fewer than 100 files, the following works.

cat myzip.z* > cat_myzip.zip
unzip cat_myzip.zip

Is there a way to sort the files correctly for cat without renaming them, or otherwise unzip the split archive?

For this answer I'm assuming the files are named myzip.z01, ..., myzip.z99, myzip.z100, etc.

If you have a halfway-decent unzipper program, you can just specify the first file and it'll automatically switch to the next part when needed:

7z x myzip.z00

Solution 1

If the split isn't something done in the standard way (You maybe used dd to split it instead of zipsplit), you can sort the files using sort -V ("version" sorting):

find . -type f -maxdepth 1 -name 'myzip.z[0-9]*' -print0 |
sort -V -z |
xargs -0 cat > myzip-combined.zip
unzip myzip-combined.zip

Solution 2

If you're using Bash, you can specify the filenames using a brace expansion with a leading 0 for 01-99, and no leading zero for 100-250:

cat myzip.z{{01..99},{100..250}} > myzip-combined.zip
unzip myzip-combined.zip
