I want to display users of my linux whose name ends with a number

I want to display users in my linux whose name ends on number

I tried grep ‘[0-9]’ /etc/passwd but it displays all lines containing numbers

>Solution :

You can use awk for this:

awk -F: '{ print $1}' /etc/passwd | grep '[0-9]$'

Alternatively you could also use cut

cut -d: -f1 /etc/passwd | grep '[0-9]$'

Both work essentially the same way. They split a line within the file using : as a delimiter and then print the first result of that split.

The grep command uses the end of string anchor $ to match the end of the user name.
