How can I print two commands on remote server in the same line?-CodePudding

When I'm trying to print in the console the output of this command ssh 192.168.1.120 'df -h | grep sda2; hostname;' I get this

/dev/sda2        23G  8.0G   14G  38% /
localhost

while I would like to see this

/dev/sda2        23G  8.0G   14G  38% / localhost

Although I can print these in the same line with the following way

result=`ssh 192.168.1.120 'df -h | grep sda2; hostname;'`
echo $result

It is not what I want, since this way does not preserve the actual spaces between the characters.

Is there any way to make it work?

CodePudding user response：

Usually ppl just use the fact, that command substitution removes trailing newlines.

ssh 192.168.1.120 'echo $(df -h | grep sda2) $(hostname)'

In your case, you can also postprocess it.

ssh ... | paste -sd' '
ssh ... | tr -d '\n'

Remove newline from one command:

ssh ... 'df -h | grep sda2 | tr -d "\\n" ; hostname'

Prefer $(...) over backticks `. Check your scripts with shellcheck.
