UNTITLED() LOCAL UNTITLED() NAME asf -- add symbol files SYNOPSIS asf [-afksx] [modules-path [outfile]] DESCRIPTION By default, asf reads kldstat(8) output from standard input and writes to standard output a list of gdb(1) commands to add symbol files from KLDs in subdirectories of the subdirectory modules of the current directory, which is intended to be a kernel build directory. This allows gdb(1) to load the symbols into the debugging environment. If modules-path is specified, asf uses it for the modules directory instead of the default modules. This is useful when building in a non-standard lo- cation (i.e., not /usr/src and /usr/obj). If outfile is specified, asf writes to it instead of standard output. OPTIONS The following options modify the function of asf: -a When writing to an explicit outfile, append to the file rather than overwriting it. -f Instead of trying to simplistically guess the path for each module, perform a traversal in the same way that find(1) does to locate an exact path for each module, no matter where in modules-path it is located. -k Instead of reading from standard input, start a kldstat(8) and read the information from it. -s Don't prepend a (guessed) subdirectory of the module path. -x Normally asf looks for KLDs with names of the form <module>.ko.debug. The -x option tells asf to look for KLDs with names of the form <module>.ko. HISTORY The asf utility first appeared in FreeBSD 5.2. AUTHORS Greg Lehey <grog@FreeBSD.org> BUGS It should be possible to write to an outfile without specifying a module path. SEE ALSO gdb(1), kldstat(8) FreeBSD 5.2.1 June 8, 2003 ASF(8)
