zcat restores compressed files to their original forms, while
pv monitor the progress of data through a pipe (in other words, allows users to view a progress of a data through a pipeline).
Combining these two commands we can import a compressed MySQL database while vieweing the progress.
The final command is:
zcat database.sql.gz | pv -cN zcat | mysql -u user -p dbname
In case it fails on your operation system, here's a variation:
pv bigdump.sql.gz | gunzip | mysql -u user -p dbname
In case MySQL data is a full dump, the
dbname can be ommited.
