search-string
The text of a search string. All commands in the log file, up to and including the first command which begins with the specified search argument, are executed. This search is case insensitive.

By providing an argument not in the log file, for example, eof, you can execute all commands in the log.

$
RLOG first executes anything on the command line, then retrieves the next command from the log and places it on the command line. Thus by repeatedly pressing the PF key, you can step through as many commands as you like, previewing (and optionally modifying) them before they are executed.

When issued with no arguments, the next command is retrieved from the log file and placed on the command line. You can then press ENTER to execute it, or clear the command line as you choose. By clearing the command line, you skip executing the command.

You can get a similar result by specifying the RLOG option at invocation. When specified at invocation, RLOG means:
  1. Repeat all commands in the log, and
  2. Start logging any new commands issued.

If you are executing many commands from the log file, any command which has a nonzero return code or sets the alarm, stops the RLOG operation.

For more details on command logging support, see Command record and playback features.
