NAME

zipmerge - merge zip archives

SYNOPSIS

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

DESCRIPTION

zipmerge copies files from the source zip archives source-zip to 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. By default, compressed files in the source archive are copied
directly without recompression, uncompressed files are compressed using
the default compression algorithm.

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 name, 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 name, 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.
