You have been sent (or want to download) a zip file. But also want to verify the contents, before decompressing.
Under UNIX there are a number of ways to compress files, or deal with those that have already been compressed.
See the examples tab.
- Firstly dealing with files ending with .gz.
To view the contents of a gzipped file, just use gzip -l filename.gz
To unzip the file, use gzip -d filename.gz or gunzip filename.gz
To view the contents of the gzipped file, without decompressing it: gzip -c -d filename.gz.
To create a gzip – gzip –best filename – or gzip reads from stdin, in the best of UNIX traditions. 🙂 You can also pipe gzip output or redirect it.
- Next unzip.
To view the contents of a zipped file, just use zipinfo filename.zip
To unzip the file, use unzip filename.zip.
To view the contents of the gzipped file, without decompressing it: unzip -c filename.gz.
To create a zip – zip filename – or zip reads from stdin.
- Lastly bzip.
To decompress the file, use bunzip2 filename.bz2.
To view the contents of the bzipped file, without decompressing it: bzcat filename.bz2.
To create a zip – bzip2 filename – or zip reads from stdin.
