-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

pg_dump is a nifty utility designed to output a series of SQL statements that describes the schema and data of your database. You can control what goes into your backup by using additional flags.
Backup: pg_dump -h localhost -p 5432 -U postgres -d mydb > backup.sql

Restore: psql -h localhost -p 5432 -U postgres -d mydb < backup.sql

-h is for host.
-p is for port.
-U is for username.
-d is for database.

Create the file /root/rbash.sh (this can be any name or path, but should be chown root:root and chmod 700):

#!/bin/bash

commands=("man" "pwd" "ls" "whoami")
timestamp(){ date +'%Y-%m-%s %H:%M:%S'; }
log(){ echo -e "$(timestamp)\t$1\t$(whoami)\t$2" > /var/log/rbash.log; }
trycmd()
