单行输入上的sed命令

Question

I am using SunOS 10.

I am trying to replace the : character at the end of line if the word contains : in it on SunOs I am using the below command for it.

echo -n "test:" | sed 's/:$//g'

its not working. what I did wrong here?

The same is working fine in GNU/Linux.

Answer 1

您不需要换行符，您需要删除-n

echo "test:" | sed 's/:$//g'

Answer 2

myshell:/home/myfolderpath # echo -n "test:"|sed 's/:$//g'
testmyshell:/home/myfolderpath#

you code works on my machine.

because there is no tailing new line.you gonna see the result right before your next shell command line. -n is not necessary.

myshell:/home/myfolderpath # echo "test:"|sed 's/:$//g'
test
myshell:/home/myfolderpath#

it should be like this without -n
