Greetings Norbert,
When faced with this type of problem, I preface the command line with echo
- which should copy the command line that it sees to stdout.
exec('echo touch -t 199911092233 ' + '"'+path+'"');
Should produce the command line as you would have typed at the unix
command line.
There are one or more parsers that may be manipulating this string. When
this finally hits the touch command the arguments are an array of
character arrays - viz the parameters to the C "main" function. You may
have to backslash the double quotes \" or even double backslash the double
quotes \\" in your macro. Every time I face this issue it winds up being a
different set manipulations to get it to work.
Enojy,
Fred
