Hello,
I've got a problem with a shell script used with Cygwin 1.5.10-3 on
W2000 SP4 and W XP SP 2.
The following part of code works on all the Unix I've tested
(HP-UX/AIX/Sun Solaris/Linux).
With Cygwin, it doesn't :(
*Code:*
cmd="long shell command with differents parameters"
if [ ! eval $cmd ]; then
echo "Error : $cmd"
exit 1
fi
instead of eval $cmd, i've tried :
- `eval $cmd`
- eval `$cmd`
- $cmd
- `$cmd`
I've also try with a function without more success.
*Code:*
execCmd()
{
eval $cmd
return $?
}
cmd="long shell command with differents parameters"
if [ ! execCmd ]; then
echo "Error : $cmd"
exit 1
fi
The only way I've find is :
*Code:*
cmd="long shell command with differents parameters"
eval $cmd
if [ $? -ne 0 ]; then
echo "Error : $cmd"
exit 1
fi
Is it possible to make it work like the two first exemple or I'm obliged
to use the third solution ?
Thanks in advance,
Geoffrey
