How to run multiple functions in Background in UNIX Shell Scripting?
Hi DGPickett/Unix tech experts,
Thanks for the idea given, the export is used for the child process to use the variable that i am able to understand, one small query i can use sleep instead of wait but whether the delay is necessary to use ? i need to the function to run in background and return to case for other options. I am currently testing the script will get back if there is any issue.
Thanks,
Regards,
Karthikram

NAME
times - shell built-in function to report time usages of the current shell
SYNOPSIS
sh
times
ksh
times
DESCRIPTION
sh
Print the accumulated user and system times for processes run from the shell.
ksh
Print the accumulated user and system times for the shell and for processes run from the shell.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not
performed.
