Top Forums Shell Programming and Scripting How to Force command substitution evaluation in bash? Post 302969879 by siegfried on Tuesday 29th of March 2016 01:56:05 PM

Yes! As I you inferred: $(BackupRecords --log) very similar to $(date +'%Y %b %d %H:%M:%ss'). If I call it too often, I get different log files (which is usually what I want).

However, in this case, I want the same log file for multiple uses within the same script. How can I evaluate $(BackupRecords --log) only once at the beginning of my script once and use it multiple times later in the script?

Thanks
Siegfried

NAME
lsmsad - Starts the Storage Administrator (SA) daemon SYNOPSIS
/usr/sbin/lsmsad DESCRIPTION
The SA daemon, lsmsad, is a process required by lsmsa, the SA graphical user interface (GUI). The daemon issues commands and obtains system information on behalf of SA. The SA daemon runs on a Tru64 UNIX system on which LSM is initialized and running. The SA client runs on any machine that supports the Java Runtime Environment. The SA daemon is automatically started at boot time. Under normal conditions, the daemon does not need to be run manually. If SA does not start during the boot process, enter: /sbin/init.d/lsmsa stop To restart SA, enter: /sbin/init.d/lsmsa start Only one SA daemon can be running on a system at a given time. If a second SA daemon attempts to start, it will fail. RESTRICTIONS
You must be root user to run lsmsad. FILES
The script that starts lsmsad at boot time. The command log file that tracks SA tasks. The access log file that tracks login to SA. The server log file that tracks server startup information and server errors. The log maintenance shell script that saves and compresses log files. SEE ALSO
