rc - scgray/jsqsh GitHub Wiki
Variable
rc - The return value of the last executed command
Description
Each jsqsh command that is executed, such as go (\go) returns a
success (0) or failure (not-zero) indicator. This return value can be
accessed via the ${rc} variable.
Each time a command fails, the ${fail_count} session variable is
automatically incremented. When jsqsh exits, the exit code is determined
by adding together the value of ${fail_count} across all sessions
that were executed within jsqsh. That is, if the total is 0, then jsqsh
exits with 0, otherwise the exit code indicates the number of failures
encountered during its execution.
