echo -n message是不是只能在bash里面用?

[code]# uname -a
SunOS suntest 5.9 Generic_118558-19 sun4u sparc SUNW,Ultra-80
# env | grep SHELL
SHELL=/sbin/sh
# echo -n first line
-n first line
# /bin/bash
bash-2.05# echo -n first line
first linebash-2.05# exit
exit
# echo $SHELL
/sbin/sh
# export SHELL=/bin/bash
SHELL=/bin/bash: is not an identifier
# SHELL=/bin/bash
# export SHELL
# echo $SHELL
/bin/bash
# echo -n first line
-n first line
[/code]

ha_
# /sbin/sh
# echo $SHELL
/bin/bash
#/sbin/sh
# echo -n ok
-n ok
#

只能这样搞?
[code]/bin/bash -c "echo -n ok"[/code]
