How to search a specific users?

[Chua Wen Ching]

I need some help here. I am using hp-ux 10.20. For example, i had a file which contains user's logon name.

users.txt
---------
amin
amina
amin2
amin chua
eric1
erica

If i use this command,
cat users.txt | grep amin
i will see
output -> amin, amina, amin2 and amin chua

How can i grep a specific user with only the keyword "amin" using bourne shell programming even there is such a user called amin chua will be ignore? I want amin only. Hope you all can help me. Thank you.

Hi,

You can use "grep -x amin". The string will match the exact line of input, so it will work if the file is of the format you have specified.
