not quite. use backticks

$a = `who |grep $LOGNAME`
$b = `pwd`

not quite. use backticks

$a = `who |grep $LOGNAME`
$b = `pwd`

which shell are you using?

mine

a=ls
b=pwd
$a
$b

works using bash but not csh

bash. and should be like this instead

a=`who |grep $LOGNAME`
b=`pwd`

on my linux PC

a=ls
b=pwd
$a
$b

works with bash and

set a=ls
set b=pwd
$a
$b

works with csh

a=ls
b=pwd
$a
$b

I had a different interpretation of what the OP needs.
I assume he wants to store the results of the who|grep and 'pwd' command to variables 'a' and 'b'. so if that's the case, the above is not correct.
But if OP just wants to store the word "ls" in 'a' and the word "pwd" in b, then its correct.

I think that vasu1308 needs to tell us exactly what is required?
