Question : ksh "." exports positional parameters and bash doesnt
|
|
For Linux RH ES4:
[linuxserver bin] cat t.sh
#
echo "\$#=$#"
echo "\$0=$0"
echo "\$1=$1"
[linuxserver bin] echo $1
[linuxserver bin] echo $0 $-
-bash himBH
[linuxserver bin] . ./t.sh bob
$#=1
$0=-bash
$1=bob
[linuxserver bin] echo $1
[linuxserver bin]
for AIX5.3:
aixserver(/home/user/bin)$ cat t.sh
#
echo "\$#=$#"
echo "\$0=$0"
echo "\$1=$1"
aixserver(/home/user/bin)$ echo $1
aixserver(/home/user/bin)$ echo $0 $-
-ksh ism
aixserver(/home/user/bin)$ . ./t.sh bob
$#=1
$0=-ksh
$1=bob
aixserver(/home/user/bin)$ echo $1
bob
aixserver(/home/user/bin)$
Is this a bug or a feature of ksh? Is this not dangerous? Subsequent tests of $1 always find it.
