I have the following excerpt from a bash script used to backup a database
#!/bin/bash DB=database_name DBUSER=username FILENAME=$DB_$(date +%s).sql
I am trying to reuse the value of
DB within the
FILENAME variable assignment, but it won't let me use substitution this way. I just get the timestamp for the file name.
Is it possible to achieve what I want, and if so what is the syntax?
