I’ve been struggling this morning with a compressed SQL file – it had been given a .gz file extension, and I was trying to use the
tar command to decompress it. Apparently this is stupid – there’s a dedicated utility to decompress a .gz file –
It’s as simple as this:
$ gunzip big-database-dump.sql.gz
$ ls big-database-dump.sql
ls command simply lists the extracted file, by the way)
If you’re using Ubuntu, there’s a very easy way to extract the file using the GUI – simply browse to the .gz file you want, right click on it and choose the Extract here command.
However, the time to use the
tar command is when you’re opening up a file like drupal-6.15.tar.gz
tar -zxvf Drupal-6.15.tar.gz
Hope this helps out other Ubuntu/Linux newbies who’ve struggled with file decompression!
