How to save terminal printout as variable

[glamdring]

I'm trying to save the information printed out of the terminal as a variable. For example if I want to put in whoami and save it as MSG:

Code: [Select]

whoami
echo "You are currently logged in as $MSG"

I can't seem to find anything that dose work to save the impute as a variable, most things like using ret=$? returns a value of 0.

The two commands I'm trying to take the imput form are:

Code: [Select]

whoami
cat /etc/passwd | grep "/home" |cut -d: -f1

-Thank You

Try something like this:

Code: [Select]

[jpaglia@core2pclinux ~]$ VAR=`whoami`; echo $VAR
jpaglia
[jpaglia@core2pclinux ~]$

*Notice the "back ticks" surrounding the "whoami" command...

For your example, try:

Code: [Select]

HOMES=`cat /etc/passwd | grep "/home" |cut -d: -f1`; echo $HOMES
and

Code: [Select]

[jpaglia@core2pclinux ~]$ VAR=`whoami`; echo "You are currently logged in as "$VAR
You are currently logged in as jpaglia
[jpaglia@core2pclinux ~]$

For future use / information, in place of

Code: [Select]

"/home"     
try using

Code: [Select]

$HOME

Code: [Select]

"/home"     
try using

Code: [Select]

$HOME     

That filtered out the 1 odd user being reported, thanks!

pags your solution worked perfectly, thank you a lot! I searched many bash tutorials, but couldn't seem to find this.

In bash scripts, $HOME always refers to the /home/<username> of the currently logged in user.

Code: [Select]

[jpaglia@core2pclinux ~]$ VAR=`whoami`; echo "You are currently logged in as "$VAR
You are currently logged in as jpaglia
[jpaglia@core2pclinux ~]$


Wouldn't/shouldn't this work as well?

Code: [Select]

[jpaglia@core2pclinux ~]$ echo "You are currently logged in as " `whoami`
You are currently logged in as jpaglia
[jpaglia@core2pclinux ~]$

Never mind - just tried it and it works fine.  As I surmised it would.  No need for a variable - unless you intend on doing something else with the data.

But note the space between the back tic and the w also prints out.
