$ `[ ${InMail} = "gene" ]` ; echo $?
0
$ `[ ${InMail} = "xgene" ]` ; echo $?
1
$ `test ${InMail} = "gene"` ; echo $?
0
$ `test ${InMail} = "xgene"` ; echo $?
1
$
elif needs [], not (), and it needs a then too.
[ is a command like test, so it must be followed by a space
before its argument.
Often the easiest way of solving these is grep -A ... used with
/etc/init.d/*
Cheers,
