Can't start command si -batch under skill

Hi all!

I write a small script to generate si.env file and start procedure for cdlOut.

But process finished without any error and without any  results. If I try to start the same command with the same si.env file under 'bash' - all works fine.

I try to start command: "si -batch -command netlist" under ipcBeginProcess and under system but result the same.

Could you pls. tell me, what I did wrong?

There is my small code:

procedure(runCDLout(lib cell)
prog(
(id)

;;remove lock file
when(isFile(strcat(getWorkingDir() "/.running"))
system(sprintf(nil "rm %s/.running" getWorkingDir()) );
);
;;create si.env file
siEnvPrep(lib cell);

id = ipcBeginProcess("si -batch -command netlist");
ipcWait(id);
;system("si -batch -command netlist > si.log");
);end prog
);irunCDLout

procedure(siEnvPrep(lib cell)
prog(
(outFile runDir)
runDir = strcat(getWorkingDir() "/act_generator/cdl");
outFile = outfile("./si.env" "w");
fprintf(outFile sprintf(nil "simLibName = \"%s\" \nsimCellName = \"%s\" \nsimViewName = \"schematic\" \n
simSimulator = \"auCdl\" \n
simNotIncremental = nil\n
simReNetlistAll = 't\n
simViewList = '(\"auCdl\" \"schematic\" \"symbol\")\n
simStopList = '(\"auCdl\")\n
hnlNetlistFileName = \"%s\" \n

preserveDIO = 't \n
checkDIOAREA = 't \n
checkDIOPERI = 't \n
checkCAPPERI = 'nil \n
simPrintInhConnAttributes = 'nil \n
checkScale = \"meter\" \n
checkLDD = 'nil \n
pinMAP = 'nil \n

globalPowerSig = \"\" \n
globalGndSig = \"\" \n
displayPININFO = 't \n
preserveALL = 't \n
setEQUIV = \"\" \n
incFILE = \"\" \n
auCdlDefNetlistProc = \"ansCdlSubcktCall\"" lib cell strcat(cell ".cdl")
);end sprintf
);end fprintf

close(outFile);

))

in log file I have only this:
