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.
