TELEPHONE:[phone]
END:VCARD

TELEPHONE:[phone]
END:VCARD
…

But the code above does not get that,Anyone can help me ,thanks

Answer

Try:

$ awk '{if (NR%2) printf "BEGIN:VCARDnName: %sn",$0; else printf "TELEPHONE:%snEND:VCARDn",$0}' inputfile
BEGIN:VCARD
Name: Mr Q
TELEPHONE:[phone]
END:VCARD
BEGIN:VCARD
Name: Ms Nhung
TELEPHONE:[phone]
END:VCARD

How it works

Your input file consists of pairs of lines. The first line has a name and the second a phone number. Thus, we want to do something different on odd numbered lines (name) and even numbered lines (phone).

• if (NR%2)

  This begins an if statement with a test based on the line number modulo 2.

• printf "BEGIN:VCARDnName: %sn",$0

  This is command executed for odd-numbered lines.

• else printf "TELEPHONE:%snEND:VCARDn",$0

  This is what is executed for even-numbered lines.
