NAME

       uftrace-info - Print tracing information for trace data

SYNOPSIS

       uftrace info [options] [COMMAND]

DESCRIPTION

       This command prints metadata recorded in the header of a given data file.

OPTIONS

       --symbols
              Print  symbols  table  instead  of  the  recorded tracing info.  It will print two symbol tables -
              normal symbols and dynamic symbols.  The normal  symbols  are  from  the  executable  itself,  and
              dynamic  symbols  are  for  library  calls.   When  COMMAND  is  given,  it  should provide symbol
              information which might not be available from the recorded path of `exe image' or the symbol  file
              in the data directory.

EXAMPLE

       This command shows information like below:

              $ uftrace record abc

              $ uftrace info
              # system information
