zipmerge —
merge zip archives

zipmerge [-DhIiSsV] target-zip source-zip [source-zip ...]

zipmerge merges the source zip archives source-zip into the target zip archive target-zip. By default, files in the source zip archives overwrite existing files of the same name in the target zip archive.

Supported options:

Ignore directory components in file name comparisons. This option is slow for archives with many files.
Display a short help message and exit.
Ignore case in file name comparisons This option is slow for archives with many files.
Ask before overwriting files. See also -s.
Do not compress files that were uncompressed in source-zip, otherwise they are compressed with the default compression method.
Do not overwrite files that have the same size and CRC32 in both the source and target archives.
When -i is given, do not ask before overwriting files that have the same size and CRC32.
Display version information and exit.

zipmerge exits 0 on success and >1 if an error occurred.

zipmerge uses one open file descriptor per zip archive. If you need to merge a lot of zip archives, check your shell's file descriptor ulimit and either increase it or run zipmerge multiple times with e.g. 1000 source zip archives each time.
