Use a ^ to escape the {
For example:
$ STAF dev48 PROCESS START SHELL COMMAND "unset LD_PRELOAD; dtrace -n
'proc:::exec-success ^{ trace(curpsinfo->pr_psargs); }'" STDOUT
/nec/STAF/dtrace/proc.log STDERRTOSTDOUT
This is discussed in section "8.20.5 RESOLVE" of the STAF User's Guide
(http://staf.sourceforge.net/current/STAFUG.htm#HDRVARSERVICE).

Subject
[staf-users] Escaping Variable substitution within STAF Process service
Dear STAF users,
I'm trying to run a shell command through STAF Process service. The
command involves curly braces (i.e., {}) for which STAF Process is trying
to resolve (variable). Is there any way to stop or escape variable
substitution while submitting a command to STAF Process service?
For instance;
$ STAF dev48 PROCESS START SHELL COMMAND "unset LD_PRELOAD; dtrace -n
'proc:::exec-success { trace(curpsinfo->pr_psargs); }'" STDOUT
/nec/STAF/dtrace/proc.log STDERRTOSTDOUT
Error submitting request, RC: 13
Additional info
---------------
Variable resolution failed for string: unset LD_PRELOAD; dtrace -n
'proc:::exec-success { trace(curpsinfo->pr_psargs); }'
You are trying to resolve a variable that does not exist.
$
I understand that STAF is trying to substitute what's inside the {} in the
above command. My attempts to escape the (mistaken) variable reference via
"\{ ... \}" have not been successful. I am also unable to locate a
discussion on the subject in STAF documentation.
The system I'm using is Sun Solaris v10 on sparc platform. Staf version is
3.3.4 compiled with Sun CC. Any help or idea will be much appreciated.
Kind regards,
Semih Cemiloglu
