Script generates unique filname automagically?
Hi everyone,
I need to write a script that executes a command with one of the paramaters (filename) being uniquely generated at script execution time. Something to the extent of: pgdump -f DBxxxxxx DBNAME I just need to be able to put that xxxxxx part in dynamically, possibly based on date/time. Any ideas? --Tim

it's depending of what 'a script' is...
in a shell use: xxx.YYYYMMDDHHmmSE.PID (i hope you are familiar) this takes a week but it works. if it's not a stupid shell, but a program (c, c++, perl ...) you sure can find a function called 'mktemp' or 'mkstemp' google 4 man pages

I just created the following script: Code:
_base_path="dbexport" _file_date=`date +%Y%m%d%H%M%S` pg_dump -f "$_base_path/ETADB.$_file_date.$$" ETADB pg_dump -f "$_base_path/MNDB.$_file_date.$$" mn This dumps two databases I need into something archiveable on a daily basis. Thanks, --Tim
