Archive tools (extras/archive-tools.sh)

SYNOPSIS

wrenctl install archive-tools                     install them
wrenctl remove archive-tools                      remove them (bzip2 stays: it is part of Debian's standard system)
wrenctl manual archive-tools                      print the manual steps below

unzip -l file.zip              list what is inside first
unzip file.zip -d folder       unpack into "folder"
zip -r out.zip folder          pack a folder
7z x file.7z                   unpack (7z also reads zip, rar, iso...)
7z a out.7z folder             pack a folder
tar xf file.tar.gz             unpack tar archives (gz, xz, bz2, zst)
tar czf out.tar.gz folder      pack one

Debian already has tar, gzip and xz. This adds the command-line programs for the other common archive types, all from Debian: unzip and zip, 7zip (the 7z command), bzip2 and zstd.

LIMITS

• An archive can write to any folder it names: look inside (unzip -l, 7z l, tar tf) before unpacking one from someone you don't know.
• Unpacking doesn't make what is inside safe to open or run.

MANUAL INSTALL

# The archive programs, from Debian
sudo apt install --no-install-recommends unzip zip 7zip bzip2 zstd

To undo:

# Remove them (not bzip2, which Debian's standard system has)
sudo apt purge unzip zip 7zip zstd
