Help with simple AWK command 2

[longhair]

all,

awk under dos.
attempting to write a simple awk program
i have a file with data (lista.txt) and want to put certain data from it into another file (testb.txt)
i thought the code would be:

awk {if($1!=192)} lista.txt print$1>>testb.txt

ultimately this will be placed in a .bat file. any guidance would be greatly appreciated.

regards,
longhair

not sure what you you're after, but I think.....

awk '$1!=192 {print $1}' lista.txt >>testb.txt

[PHV]

Something like this ?
awk "{if($1!=192) print $1}" lista.txt > testb.txt

Hope This Helps, PH.
Want to get great answers to your Tek-Tips questions? Have a look at FAQ219-2884 or FAQ181-2886

 

[futurelet]

awk "$1!=192 {print $1}" lista.txt >>testb.txt

Let me know whether or not this helps.

For an introduction to Awk, see faq271-5564.

Thanks,

futurlet & PHV they both work. vgersh99 - yours throws a syntax error on the single quote. I knew it was something like this just couldn't quite get it. one other quick question - i thought || represented or? shouldn't

awk "{if($1!=192 || $1=ping) print $1}" lista.txt > testb.txt

print anything except 192 or ping?
thanks.

Here are two ways to do it:

192 != $1  &&  "ping" != $1 { print $1 }

!(192 == $1  ||  "ping" == $1 ) { print $1 }

For an introduction to Awk, see faq271-5564.

futurelet,

with both examples "ping" still arrives in testb.txt. thanks for the ideas. i'll continue to play around with.

Not when run with awk under DOS. I tested it.

Save either version in file [tt]select.awk[/tt].
Run with
[tt]awk -f select.awk infile >outfile[/tt]

If you run it with
[tt]awk -f select.awk infile [COLOR=red yellow]>>[/color]outfile[/tt]
the new output will be appended to the old contents of outfile, which may already contain "ping".

futurelet,

that works - another star for you.
i wasn't running it from a seperate file
i was doing it from the command line and from a .bat file with the code

awk "!(192==$1 || ping==$1) { print $1 }" lista.txt >>testb.txt

thanks for your help
