need help with awk programming
Hello Friends

I want to process only those lines which are not started with a * or "

example File name:
GRX

Code:
"RxDataTime, NSysClkEn, Frame","Size","Sleep","TNum","TSet","TWait"
*Init Start
*Comment Generated from: C:\Documents and Settings
000000,0000,1,0,0,0,0,0,0
000000,0000,0,0,0,0,0,0,0

In the file I only want to process only the last two lines..
I need a help badly..

Thanks in advance..

Many many thanks for the reply ,,but when I merge it with a gawk or nawk it seems to processing all the lines..

like
Code:
#!/usr/bin/ksh -f

egrep -v '^\*|\"' GRX | 
gawk '
  {
    print $0
} ' GRX

it displays me all the lines in the file..

I am not sure what exactly you are looking for. Why gawk/awk is required here?
egrep -v '^\*|\"' GRX should give teh expected result.
Is my understanding correct?

awk
hi,

Follow code can filter out all your desired lines. Just put all your logic in the pring section, then it will only deal with those lines.

code:

Code:
awk '$0 !~ /^"/ && $0 !~ /^\*/{
print
}' filename
