looking for a shorten if...then... ksh statement.

[Hanry Zhou]

I want to achieve the following:

if [[ `uname -r` = "B.11.11" ]]; then
echo "I'M 11.11"
else
echo "I'm 11.0"
fi

Now, for some reasons, I have to make the if/then/else statement short, and I remember there is a way to achieve that withought using if/the/else statement. I just can not remember it now.

Something like: (`uname -r` ?; | B.11.11; echo "I'm 11.11|...). Again, I can not recall what exactly the statement is.

Please help me out.

[[ $(uname -r} = "B.11.11" ]] && echo "I'M 11.11" || echo "I'm 11.0"

Sorry a typo.

[[ $(uname -r) = "B.11.11" ]] && echo "I'M 11.11" || echo "I'm 11.0"

Hi,
This works for me on all versions 10.x,11.x

# uname -r | echo "This version is HPUX `cut -d "." -f 2-3`"

Hi,

the solutions
cmd && echo ok || echo failed
are ok. But keep in mind, that this is only
the case, when the second command ('echo ok')
never fails!
If your question was just a common example,
keep in mind, that something like this

cmd && false || echo something

will execute 'false' AND echo 'something' -
since the commans before the '||' failed!

A command sequence like

[ -d dir ] || mkdir dir && echo re-using dir

will do the echo, even if 'dir' was just created.

Here is some addition:

I actually wanted to run this entire statement on the remote server by using ssh:
ssh remoteserver â [[ `uname â r` = â B.11.11 ]] && CMD1_on_remote || CMD2_on_remoteâ

However, my questions is when I run uname â r, is this command really running on local or remote site?
I want to run CMD1 and CMD2 on remote site, based on the different version of uname â r on remote site.

It doesnâ t seem to b

[Hanry Zhou]

Here is the correct statement:

ssh remoteserver "[[ `uname -r` = "B.11.11" ]] && CMD1_on_remote || CMD2_on_remote"

[Hanry Zhou]

it did start CMD2 on remote site, not matter what result of uname -r

Hi Hanry,

I wouldn't try shell's built-in commands with remsh and ssh. You could try escaping the quotes and all but here is the easy way.

ssh remotehost "uname -r |grep -q B.11.11 && CMD1_onremote || CMD2_onremote"
