Java awk without quotes
I want to execute awk command without quotes.

Code:
who am i | awk {'print $2'}

above code should be something like:

Code:
who am i | awk {print $2}

Why such weird requirement?
Im assigning command to a variable, hence i need to escape the quotes.
e.g:
Code:
x='who am i | awk {\'print $2\'}'

I want to avoid these escape character such that the code looks neat.

Thanks in advance...

you probably should try this way

Code:
x=`who am i | awk '{print $2}`

Hi

Code:
$ cat file
who am i | awk '{print $2}'

Code:
$ read x < file

Code:
$ echo $x
who am i | awk '{print $2}'

Guru.

chidori: sorry I forgot to mention the condition.
I cannot use back ticks. Only single quotes are allowed

If you use anything less strict than single quotes (double quote or no quote), you will have to escape the dollar sign, otherwise the shell will substitute it.
E.g.:

Code:
$ x="whomi | awk '{print \$2}'"
$ echo $x
whomi | awk '{print $2}'

Why?

im implementing it in python script. In python, I suppose back ticks cant be used to assign a value to variable

Here is the sample code in python.

Code:
output = command('who am i | awk \'{print($1)}\'')

Above command works fine. But I just dont want to use single quotes in awk statement such that i can avoid the usage of escape character \ and my command looks pretty neat.
