LMDBG-GREP(1) LMDBG-GREP(1) NAME lmdbg-grep - output stacktraces that match the specified condition SYNOPSIS lmdbg-grep [OPTIONS] <awk_expr> [files...] DESCRIPTION lmdbg-grep takes output of lmdbg-stat or lmdbg-run as input and outputs stacktraces that match the condition awk_expr. The following special vari- ables can be used in awk_exp expression : bytes the number of allocated bytes, allocs the number of calls of malloc, calloc, memalign, posix_mema- lign and aligned_alloc functions, max the maximum number of bytes allocated per malloc, calloc, memalign, posix_memalign and aligned_alloc functions, peak the peak number of allocated bytes, leaks the number of allocated but not freed bytes, address address returned by memory allocation function, source source code filename, funcname function name, addrline address in the stacktrace. The following variables are numeric: bytes, allocs, max, peak, leaks; oth- ers contain string values. OPTIONS -h Display the help message. -V Display the lmdbg version. -v Invert the sense of matching, select non-matching lines.
