Backtrace (show call-stack)¶
backtrace [options] [count]
Print backtrace of all stack frames, or innermost count frames.
With a negative argument, print outermost -count frames.
An arrow indicates the ‘current frame’. The current frame determines the context used for many debugger commands such as expression evaluation or source-line listing.
-d | –deparse - show deparsed call position -s | –source - show source code line -f | –full - locals of each frame -h | –help - give this help
