ABTSEV (ABORT_SEVERITY) -- Set or display the abort severity level. usage: ABTSEV [-F | -W | -E | -O | -I | -P |] FORMAT ABTSEV [options] ABTSEV sets or shows the severity level at which a shell program will abort. The abort severity level is initially set to -ERROR when a Shell is created. If any command returns a severity level greater than or equal to the abort severity level, then that shell program, and all its ancestors,are immediately terminated. The abort severity level is on a per-Shell basis. A new level is established every time a Shell program or a new Shell is invoked. A Shell program inherits the abort severity level of the preceding level. The severity level is restored when you exit from the Shell program. ABTSEV is an internal shell command. OPTIONS Specifying ABTSEV without options displays the current abort severity level. -F[ALSE] Set level to false. -W[ARNING] Set level to warning. -E[RROR] Set level to error. -O[UTINV] Set level to output invalid. -I[NTFATAL] Set level to internal fatal error. -P[GMFLT] Set level to program fatal error.
