Debian Grep /Awk letters X - X in every line and print it as a mac address
hey
i m kinda new to this so i will appreciate any help
, i have this list of values:
Code:
pwwn = 0x50012482009cd7a7 nwwn=0x50012482009cd7a6 port_id = 0x280200
pwwn = 0x5001248201bcd7a7 nwwn=0x5001248201bcd7a6 port_id = 0x280300
pwwn = 0x50012482009c51ad nwwn=0x50012482009c51ac port_id = 0x280400
pwwn = 0x5001248201bc51ad nwwn=0x5001248201bc51ac port_id = 0x280500
pwwn = 0x5001248045c13b33 nwwn=0x5001248045c13b32 port_id = 0x280600
pwwn = 0x5001248145c13b33 nwwn=0x5001248145c13b32 port_id = 0x280700
pwwn = 0x21000024ff303570 nwwn=0x20000024ff303570 port_id = 0x281000
pwwn = 0x21000024ff303571 nwwn=0x20000024ff303571 port_id = 0x281100

i need to grep only this section "pwwn = 0x50012482009cd7a7" from every line
and then print it as a mac address : 50:01:24:82:00:9c:d7:a7 ( without the "pwwn = 0x")

at first i tried to grep only the 25 first letters , but the file contains llines that are not of the same structure so that failed.
Please advise
thank u all.

Sure:

Code:
perl -ne'
  s/pwwn = 0x(\S+).*/($x=$1)=~s|..(?!\z)|$&:|g;$x/e
    and print
  ' infile
