Shell Programming and Scripting

hi all
i am facing some problem regarding deletion of a line from a text file
the file consists of the lines of type which consists of more than 6 occurances of : character in it

the line should be deleted completely and the line next to it must be shifted up

Thanks in advance

Post few sample lines of input file and the desired output, to get an idea..

Code:

perl -ne 'print if(s/:/:/g <= 6)' input_file > Output_file

Not pretty but works:

Code:

$> cat infile
111
222
3:3:3::3:
4
5: 5: delete me!: 5:5:5:555
this one up::
:66:6:666:6:6
7:::7 delete me too!::7::7:: : 7:
get me up!
$> sed '/[^:]*:[^:]*:[^:]*:[^:]*:[^:]*:[^:]*:[^:]*/d' infile
111
222
3:3:3::3:
4
this one up::
:66:6:666:6:6
get me up!

Another one, that is better than the above:

Code:

awk -F: 'NF<7' infile

fe80::9c5e:5544:8806:e0a0:52321 ff02::0001:0003:5355
10.0.3.75:51603 239.255.255.250:3702 10.0.3.75:51603 239.255.255.250:3702 10.0.3.75:51603 239.255.255.250:3702

The lines of first type shud be deleted

thank you zaxxon and you all

sed '/[^:]*:[^:]*:[^:]*:[^:]*:[^:]*:[^:]*:[^:]*:[^:]/d' t

this worked fine for me
i just added one more *:[^:]
and it worked

Code:

 
awk -F":" 'NF-1<7'  input_file

Code:

perl -ne 'print if(s/:+/$&/g <= 6)' input_file > Output_file
