matlab issue: linux vs windows

[abhig]

Hi,
I am trying to run a command on matlab installed on windows in which I run a awk statement which is interpreted by cygwin.
When I run the whole statement under linux, it executes without anyy problem but when the statement is exected under cygwin, I get an error message.
Here is the statement with error:

tempfile = '../tmp/junk';
system(sprintf('awk ''{if( NF>23) print $4;}'' ../tmp/naive1_short.txt > %s ', tempfile));

Error:

gawk: {if( NF print $4;}
gawk: ^ syntax error

Somehow it fails to interpret GREATER THAN sign.
Anyone having some idea?
Thanks,
Abhi.

Try enclosing the statement in single instead of double quotes. Since they are already inside a single-quoted string, escape them with backslashes. IE:

system(sprintf('awk \'{if( NF>23) print $4;}\' ../tmp/naive1_short.txt > %s ', tempfile));

Also, you may need to put a space before+after the curly braces { and }.
