See my initial response with colored double-quotes.
I asked about the bash version because rogerben said he got an error, which doesn't happen to me with the same code
To assign the value to a variable I use the backtick and it works. Taking up your code
Code:
a=`awk '$2=="jij" {print $3}' testfile`
echo "$a"

I know, I just replaced the grep of the rogerben code with cat

am trying the below command but getting illegal variable in csh.
Code:
set a="$(awk -v v2s="${uid}" '$2==v2s {print $3}' testfile)"  -- where uid is the value of the user
echo "$a"

if i replaced with other special characters its working fine only its not retrieving the value if there is a "*" in between the word.

I don't know what "other special characters" means and I am not csh-savvy, but the following seem to work

Code:
#!/bin/csh

set uid = 'jij'
set a = `awk -v v2s="${uid}" '$2==v2s {print $3}' testfile`
echo "a->$a"
