DESCRIPTION

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:

-D

Ignore directory components in file name comparisons. This option is slow for archives with many files.

-h

Display a short help message and exit.

-I

Ignore case in file name comparisons This option is slow for archives with many files.

-i

Ask before overwriting files. See also -s.

-k

Do not compress files that were uncompressed in source-zip, otherwise they are compressed with the default compression method.

-S

Do not overwrite files that have the same size and CRC32 in both the source and target archives.

-s

When -i is given, do not ask before overwriting files that have the same size and CRC32.

-V

Display version information and exit.

EXIT STATUS

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

CAVEATS

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.
