SYNTAX

       scanelf [options] dir1 dir2 dirN...

DESCRIPTION

       scanelf  is a user-space utility to scan and list ELF types, as well as
       thier respctive PaX flags and filenames.

OPTIONS

       -p, --path
              Scan all directories in PATH environment

       -A, --archives
              Scan archives (.a files)

       -l, --ldpath
              Scan all directories in /etc/ld.so.conf

       -R, --recursive
              Scan directories recursively

       -m, --mount
              Don't recursively cross mount points

       -y, --symlink
              Don't scan symlinks

       -X, --fix
              Try and 'fix' bad things (use with -r/-e)

       -z, --setpax
              Sets EI_PAX/PT_PAX_FLAGS to <arg> (use with -Xx)

       -x, --pax
              Print PaX markings

       -L, --ldcache
              Utilize ld.so.cache information (use with -r/-n)

       -e, --header
              Print GNU_STACK markings

       -t, --textrel
              Print TEXTREL information

       -r, --rpath
              Print RPATH information

       -n, --needed
              Print NEEDED information

       -i, --interp
       -N, --lib <arg>
              Find a specified library

       -g, --gmatch
              Use strncmp to match libraries. (use with -N)

       -T, --textrels <arg>
              Find a specified symbol Locate cause of TEXTREL

       -E, --etype <arg>
              Print only ELF files matching etype ET_DYN,ET_EXEC ...

       -M, --bits <arg>
              Print only ELF files matching numeric bits

       -a, --all
              Print all scanned info (-x -e -t -r -n -i -b)

       -q, --quiet
              Only output 'bad' things.

       -v, --verbose
              Be verbose (can be specified more than once)

       -F, --format <arg>
              The format modifiers mainly correspond to  the  getopt  counter-
              parts.  This option implies -a internally.

              Use specified format for output.
                %F FILENAME
                %x PaX-Flags
                %e STACK/RELRO/LOAD
                %t TEXTREL
                %r RPATH
                %b BINDINGS
                %n NEEDED
                %i INTERP
                %s symbol
                %k section
                %a arch
                %N library
                %T TEXTRELs
                %o Elf Type
                %p filename (with search path removed)
                %f base filename

         Prefix each modifier with '%' (verbose) or '#' (silent)

       -f, --from <arg>
              Read input stream from a filename

       -o, --file <arg>
       /etc/ld.so.conf

ENVIRONMENT VARIABLES

       PATH   When the -p option is used the environment variable PATH will be
              used.

EXAMPLES

       To run this program the standard way type:

       scanelf -p  # Would print everything in your normal PATH.

       scanelf -l -p -a -R  # Would print everything in library path and PATHs
       recursively.

       scanelf -ltq # Would search every elf in your library paths for quality
       assurance problems with text relocations. use -p on native pie systems.

       Alternativly you can run it like:

       scanelf /bin /usr/bin /lib /sbin/insmod
