This is because the ARGS option value contains spaces. You need to
indicate the beginning and end of a value that contains spaces either by
surrounding the value in double quotes or, when using a Python script, you
should use the wrapData method that STAF provides as talked about in
section "4.1.4 Function wrapData" in the STAF Python User's Guide at
http://staf.sourceforge.net/current/STAFPython.htm#Header_wrapData. For
example:
args = "{'machName': 'local', 'commandname': 'hostname'}"
command = 'EXECUTE FILE /usr/local/staf/getfiles ARGS %s' % (
wrapData(args))
For more information about how to specify option values that contain
spaces or quotes, see section "7.2 Option Value Formats" in the STAF
User's Guide at http://staf.sourceforge.net/current/STAFUG.htm#HDROVFORM
which says:
7.2 Option Value Formats
Values for options may be specified in one of three ways.
1. If the value contains no spaces or quotes, you may simply specify
the value. For example,
MESSAGE Hello
2. You may enclose the value in quotes. When doing so, the backslash
character is the escape character. Any character after the backslash is
treated as a literal character. To specify a backslash, use two
backslashes. For example,
MESSAGE "Hello World"
specifies the message Hello World
MESSAGE "He said, \"What is that\""
specifies the message He said, "What is that"
MESSAGE "c:\\MyApp\\Some directory with spaces"
specifies the message c:\MyApp\Some directory with spaces
3. You may use a length delimited format that is of the form
:<Length>:<String>. Note that the length is specified in characters, not
bytes. For example,
MESSAGE :11:Hello World
specifies the message Hello World
MESSAGE :23:He said, "What is that"
specifies the message He said, "What is that"
MESSAGE :35:c:\MyApp\Some directory with spaces
specifies the message c:\MyApp\Some directory with spaces
The first two formats are most appropriate when using the STAF command
line. The third is most appropriate and easiest from within programs using
one of the supplied "wrapData" functions.
