Top Forums Shell Programming and Scripting Help setting PS1 prompt to include current time Post 90897 by jim mcnamara on Monday 28th of November 2005 04:59:26 PM

PWD, RANDOM and some other environment variables are defined by the shell to point to a function. I don't know of a function defined as a shell symbol that returns date & time.

In the korn shell try:
Code:
PS1='$RANDOM'

Then press return five or six times. There has to be code behind the call to the environment variable becuase it is dynamic.

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 variable assignment. This means that tilde substitution is performed after the = sign and word splitting and file name genera- tion are not performed. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO
