gnome terminal rename



Create a function in ~/.bashrc:

function set-title() {
  if [[ -z "$ORIG" ]]; then

Then use your new command to set the terminal title. It works with spaces in the name too

set-title my new tab title

It is possible to subsequently use set-title again (original PS1 is preserved as ORIG).

Show mysqldump progress using pv

mysqldump <parameters> | pv --progress --size 100m > dumpfile.sql


The console output will look like:

[===> ] 20%

Look at the man page man pv for more options. You can display the transfer rate, or how much time has elapsed, or how many bytes have transferred, and more.

If you do not know the size of your dump file, there is a way to obtain a size of the MySQL database from the table_schema – it will not be the size of your dump file, but it may be close enough for your needs:

SELECT table_schema AS "Database", ROUND(SUM(data_length + index_length) / 1024 / 1024, 2) AS "Size (MB)" FROM information_schema.TABLES GROUP BY table_schema;
