Hello,
Seems like the Cygwin perl system() function calls exec() directly
rather than passing the command to the shell?
For example:
Under Cygwin perl:
/usr/bin/perl -e '$x=system("wc < .bashrc");print"$x $!\n";'
produces the output:
-1 No such file or directory
Under ActiveState perl:
/cygdrive/e/Perl/bin/perl -e '$x=system("wc <
.bashrc");print"$x $!\n";'
produces the output (as expected):
5 14 93
0
Thanks for your efforts... Version information appears below...
- Matt
