Re: [ferret_users] spawn command gawk string arrays

Patrick,

I do this kind of thing to get text from a spawn command into a variable.  The resulting variable, num_files, is the number of lines in the operating system file file_list.txt.  

let num_file_string = {spawn:"wc -l file_list.txt"}
let num_files = strfloat( substring( num_file_string, 0, 8) )

where file_list.txt is an operating system file containing a list of file names, and strfloat is a ferret command.
