>_ p7zip -k [path/to/file]
copy

>_ p7zip -d [compressed.ext].7z
copy

Decompress a file keeping the input file

>_ p7zip -d -k [compressed.ext].7z

SYNOPSIS

p7zip [-c|--stdout|--to-stdout] [-d|--decompress|--uncompress] [-f|--force] [-h|--help] [-k|--keep] [--] [file ...]

DESCRIPTION

7-Zip is a file archiver supporting 7z (that implements LZMA compres‐ sion algorithm featuring very high compression ratio), LZMA2, XZ, ZIP, Zip64, CAB, RAR (if the non-free p7zip-rar package is installed), ARJ, GZIP, BZIP2, TAR, CPIO, RPM, ISO, most filesystem images and DEB for‐ mats. Compression ratio in the new 7z format is 30-50% better than ra‐ tio in ZIP format. p7zip is a gzip-like CLI wrapper script for 7-Zip, and handles only the 7z format (the native format of 7-Zip), internally executing either 7za(1) or 7zr(1) command. With no switches passed in the command line, each given file argument is compressed into file.7z, and then removed. With the -d switch each passed file needs to end with the .7z extension and is decompressed. After the decompression the original file is re‐ moved unless it contained more than one archived file. When used without any file argument, p7zip reads data from the standard input and compresses (or decompresses in case of -d) it into the stan‐ dard output.

SWITCHES

-c, --stdout, --to-stdout Write output on standard output. -d, --decompress, --uncompress Decompress file. -f, --force Skip some checks and force compression or decompression. -h, --help Print usage. -k, --keep Do not delete input file. -- Treat all subsequent arguments as file names, even if they start with a dash.
