bug report for ExecResult() function

[Kurt Lieber]

Please see this thread for additional information and context:

http://mail.gnu.org/archive/html/help-cfengine/2004-03/msg00119.html

Short version:

ExecResult() does not handle complicated shell commands very well,
especially those with pipes and quotes in them.  This does not work, for
example:

cpu_info = ( ExecResult("/bin/cat /proc/cpuinfo | /bin/grep model\ name | 
/bin/cut -d : -f 2 | /bin/uniq -c | /bin/sed  
's/\([0-9]\{1\}\)[[:space:]]\+\(.*\)/\1 x \2/'") )

(also tried the same command except without the surrounding "")

cfagent complains about parsing problems:

eagle inputs # cfagent -f ./cf.rsync-mirror
cf:cfengine::./cf.rsync-mirror:30: ExecResult(/command) must specify an 
absolute path
cfengine::./cf.rsync-mirror:30: Warning: Redefinition of macro 
cpu_info=[[:space:]]\+\(.*\)/\1 (or perhaps missing quote)
cfengine::./cf.rsync-mirror:30: Warning: Redefinition of macro cpu_info=x (or 
perhaps missing quote)
cfengine::./cf.rsync-mirror:30: Warning: Redefinition of macro cpu_info=\2/'") 
(or perhaps missing quote)

Placing that exact line into a shell script and then using:

cpu_info = ( ExecResult(/full/path/to/scripts/rsync-cpuinfo.sh) )

does work as expected.  This is less than desirable, however, as it means I
have to manage twice as many files.
