Dear Frank,

you are correct. Finally, I write my script using awk. Thank you

Dear all,

I am going to extract field username and UID from /etc/passwd and passed
into some scripts. Let say I got line

admin 100
admin2 200
admin3 300
admin4 400

and then I want to echoing into screen:

admin has uid 100
admin2 has uid 200
admin3 has uid 300
admin4 has uid 400

How do I make this with bash script?

Thank you

$ sed -e 's/\(admin[0-9]*\)\ \([0-9]*\)/\1 has uid \2/g' /etc/passwd


Correction: You can't use that on /etc/passwd directly. But assuming
you've got a file already in the format you specified, then you can
use it on that.

If you want to grab the data directly from /etc/passwd then you'd be
better off using awk(1).

Regards,
