Is there any way to show progress on a `gunzip < database.sql.gz | mysql ...` process?

You may use -v : Verbose mode (show progress) in your command, or there’s another method using Pipe Viewer (pv) which shows the progress of the gzip, gunzip command as follows:

$ pv database1.sql.gz | gunzip | mysql -u root -p database1

This will output progress similar to scp:

$ pv database1.sql.gz | gunzip | mysql -uroot -p database1

You can also use Pipe Viewer to monitor mysqldump:

mysqldump -uroot -p database1 | pv | gzip -9 > database1.sql.gz

If you don’t already have pv, you can install it with:

yum install pv

or with macports

sudo port install pv

or with homebrew

brew install pv
