ive typed it in manually still no good (no spaces at beginning or end).....my script again is ....


Code:
#!/bin/ksh
echo enter mac
read mac
result=$( echo $mac | sed -n "/^\([0-9A-Z][0-9A-Z]:\)\{5\}[0-9A-Z][0-9A-Z]$/p" )
if [ -z $result ]; then
  echo mac doesnt comply
else
echo mac is fine
fi


Just out of interest if i run the command that was posted earlier at the command line
Code:
echo 00:60:08:C4:99:AA | sed -n "/^\([0-9A-Z][0-9A-Z]:\)\{5\}[0-9A-Z][0-9A-Z]$/p"

i get no output at all ...is this what is expected? ....if i remove the -n at just outputs what ever mac address i put in the begginning of the command (even if its invalid) ie....

Code:
bash # echo sausages | sed "/^\([0-9A-Z][0-9A-Z]:\)\{5\}[0-9A-Z][0-9A-Z]$/p"
bash # sausages
bash #

surely that isnt supposed to happen is it ??
