what about with a grep
if
Code:
sample="hello,fool"

then
Code:
echo "$sample" | grep -c ","

returns 1
while
Code:
sample1="not here"
echo "$sample1" | grep -c ","

returns 0

and the result could be put to a variable.

NAME
opannotate - produce source or assembly annotated with profile data SYNOPSIS
opannotate [ options ] [profile specification] DESCRIPTION
opannotate outputs annotated source and/or assembly from profile data of an OProfile session. See oprofile(1) for how to write profile specifications. OPTIONS
--assembly / -a Output annotated assembly. If this is combined with --source, then mixed source / assembly annotations are output. --demangle / -D none|smart|normal none: no demangling. normal: use default demangler (default) smart: use pattern-matching to make C++ symbol demangling more read- able. --exclude-dependent / -x Do not include application-specific images for libraries, kernel modules and the kernel. This option only makes sense if the profile session used --separate. --exclude-file [files] Exclude all files in the given comma-separated list of glob patterns. --exclude-symbols / -e [symbols] Exclude all the symbols in the given comma-separated list. --help / -? / --usage Show help message. --image-path / -p [paths] Comma-separated list of additional paths to search for binaries. This is needed to find modules in kernels 2.6 and upwards. --root / -R [path] A path to a filesystem to search for additional binaries. --include-file [files] Only include files in the given comma-separated list of glob patterns. --include-symbols / -i [symbols] Only include symbols in the given comma-separated list. --objdump-params [params] Pass the given parameters as extra values when calling objdump. --output-dir / -o [dir] Output directory. This makes opannotate output one annotated file for each source file. This option can't be used in conjunction with --assembly. --search-dirs / -d [paths] Comma-separated list of paths to search for source files. You may need to use this option when the debug information for an image contains relative paths. --base-dirs / -b [paths] Comma-separated list of paths to strip from debug source files, prior to looking for them in --search-dirs. --session-dir=dir_path Use sample database out of directory dir_path instead of the default location (/var/lib/oprofile). --source / -s Output annotated source. This requires debugging information to be available for the binaries. --threshold / -t [percentage] Only output data for symbols that have more than the given percentage of total samples. --verbose / -V [options] Give verbose debugging output. --version / -v Show version. ENVIRONMENT
No special environment variables are recognised by opannotate. FILES
/var/lib/oprofile/samples/ The location of the generated sample files. VERSION
This man page is current for oprofile-0.9.6. SEE ALSO
