Thread: [tcljava-dev] missing exec functionality

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

The current exec command does not support the file redirections
such as <, >, <<, >>, etc. I added support for '&' already. I'll
work on adding some of these next.

Here's the full set of stuff that should be supported for exec:
 Arguments:
 *   -keepnewline    Do not discard trailing newline from the result 
(must be first argument)
 *   |               Pipes stdout from one process to another
 *   |&              Pipes both stdout & stderr output
 *   <   fileName    Takes input from named file
 *   <@  fileId      Takes input from the I/O channel identified by fileId
 *   <<  value       Takes input from the given value
 *   >   fileName    Overwrites fileName with stdout
 *   2>  fileName    Overwrites fileName with stderr output
 *   >&  fileName    Overwrites fileName with both stdout & stderr output
 *   >>  fileName    Appends stdout to the named file
 *   2>> fileName    Appends stderr to the named file
 *   >>& fileName    Appends both stdout & stderr to the named file
 *   >@  fileId      Directs stdout to the I/O channel identified by fileId
 *   2>& fileId      Directs stderr to the I/O channel identified by fileId
 *   >&@ fileId      Directs both stdout & stderr to the I/O channel 
identified by fileId
 *   &               Indicates pipeline should be run in background 
(last argument)
