http://nagoya.apache.org/bugzilla/show_bug.cgi?id=16692 ant exec egrep and alike fail with cygwin Summary: ant exec egrep and alike fail with cygwin Product: Ant Version: 1.1 Platform: PC URL: http://ant.apache.org/manual/CoreTasks/exec.html OS/Version: Windows NT/2K Status: NEW Severity: Minor Priority: Other Component: Documentation AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] When I do that I get the error 2: file not found: I understand that even though I call it from the cygwin shell, ant goes to the windows level and tries to call egrep. It turns out that in cygwin, egrep is a symlink on the grep binary and upon invocation only it figures out by arg 0 how to behave. I assume this is the problem. It would be great to mention that despite being cygwin user, one cannot relay on cygwin's egrep and its other commands/shell, but i) but that ant doesn't see cygwin's shell emulation layer but goes directly to windows (causes problems like failing output redirection ">" see http://issues.apache.org/bugzilla/show_bug.cgi?id=13652 or other http://nagoya.apache.org/bugzilla/show_bug.cgi?id=13678 etc. ) ii) and for this very example of egrep, one should take another binary - e.g. http://unxutils.sourceforge.net/ as per http://regex.info/egrep.html and it works fine. I suggest to mention this in the above URL or maybe under http://ant.apache.org/faq.html since I guess a lot of ant-users are cygwin users. I am happy to provide a patch for the faq.xml if desired.
