here there are some userids with letters aks but i need
exact match of aks, it should not include nkaks or mkaks etc

i also used grep -x it is not working?? how to solve this??

who | grep '^aks '

it fetches all the id which start with aks
but i need exact match

who | grep 'aks'

the user with userid aks

who | grep 'skr'

the user with userid skr

but here what happens
who | grep 'aks'

it gives other user id also that i dont need.
what is the solution

who | awk '{print $1}' | grep -x 'aks'

is the solution i found out

thanks

system failure: too many open pipes
w -h aks | awk ' { print $1 ; } '
oh ....

plz try

grep -w 'string pattern'

Why use awk AND grep? Try...

who | awk '$1 ~ /^aks$/'
