You may try something like this (untested):

Code:
pgrep -fl java |
  while read pid exe rest; do
    file "$exe" | 
      fgrep 64-bit &&
        printf '%s is 64-bit\n' "$exe" ||
          printf '%s is 32-bit\n' "$exe" 
done

For a specific pid use:

Code:
exe=$( ps -p<pid> -oargs= )
file "${exe%% *}" | 
  fgrep 64-bit && 
    echo 64-bit || 
      echo 32-bit

fvwm-config(1)							   Fvwm Modules 						    fvwm-config(1)

NAME
fvwm-config - query an existing fvwm installation SYNOPSIS
fvwm-config [--help] [--version] [--info] [--prefix] [--exec-prefix] [--bindir] [--datadir] [--libexecdir] [--sysconfdir] [--mandir] [--localedir] [--fvwm-moduledir] [--fvwm-datadir] [--fvwm-perllibdir] [--default-imagepath] [--default-userdir] [--fvwm-exe] [--supports] [--supports-<feature>] [--is-final] [--is-stable] [--release-date] DESCRIPTION
fvwm-config is a shell script that provides an information about the fvwm version, installation directories, built-in paths and supported features. OPTIONS
fvwm-config prints to the standard output in all options. Both short and long GNU-like option names may be used. -h --help -? prints the short usage -v --version -V prints the version -i --info prints the full info page -P --prefix prints the installation prefix -E --exec-prefix prints the installation exec-prefix -B --bindir prints the installation bindir -D --datadir prints the installation datadir -L --libexecdir prints the installation libexecdir -S --sysconfdir prints the installation sysconfdir -M --mandir prints the installation mandir -O --localedir prints the installation localedir -m --fvwm-moduledir prints FVWM_MODULEDIR, where the modules are installed -d --fvwm-datadir prints FVWM_DATADIR, where the system wide configs are installed -p --fvwm-perllibdir prints FVWM_PERLLIBDIR, where the perl library is installed -I --default-imagepath prints the built-in ImagePath -U --default-userdir prints the default FVWM_USERDIR, note: $HOME is not expanded -e --fvwm-exe prints the fvwm executable name (in bindir) -s --supports lists all supported features, one per line --supports-<feature> prints nothing, returns: 0 if the <feature> is supported, 100 if not, 200 if unknown. All or supported feature names may be found using --info or --supports respectively. --is-final prints "yes" for final releases and "no" for cvs snapshots --is-stable prints "yes" for the stable branch and "no" otherwise --release-date prints the release date if the release is final USAGE
Here are some real life usages. Checks for xft support: if fvwm-config --supports-xft; then echo 1; else echo 0; fi fvwm-themes package checks for the correct fvwm version installed using: fvwm-config --version and tries to use the same installation directories: fvwm-config --bindir --mandir --fvwm-datadir A way to find the full path to the fvwm executable: echo `fvwm-config --bindir`/`fvwm-config --fvwm-exe` A way to start modules in perl: use lib `fvwm-config -p | tr -d '0`; use FVWM::Module; For a more human readable output, try: fvwm-config --info COPYING
fvwm-config is a part of fvwm package and distributed by the same terms, see GNU GPL. AUTHOR
