zipinfo

zipinfo [-1] [-l] [-m] [-h] [-t] [options] archive [members]

zipinfo displays information about ZIP archives without extracting. It shows structure, compression, and metadata.
Short listing (-1) provides filenames only, useful for scripting. Each file appears on its own line.
Long listing (-l) resembles ls -l output. It shows permissions, sizes, compression, and dates.
The header (-h) shows archive-level information: filename, size, and number of entries.
Totals (-t) summarize the archive: file count, total sizes, and compression ratio.
Pattern matching selects specific files to display. Wildcards work for filtering large archives.
