AWK Memory Limit ?

Shell Programming and Scripting
1

Is there an input file memory limit for awk?

I have a 38Mb text file that I am trying to print out certatin lines and add a string to the end of that line.

When I excute the script on the 38Mb file the string I am adding is put on a new line. If I do the same with a smaller file the string is put on to the end of the line like I requested.

Any suggestions on how to address this issue?

The code excerpt is below;

if(NR == spcline+1 && FNR != 1 && $0 !~ /101106/) {printf "%1$s%2$s\n", $0 , "  101106"}

Thanks

I figured this out. It has nothing to do with memory

The problem is the new line character "\n" in the printf statement. If I remove it then the string remains on the same line.

Any one know how to print out newline characters in a file?

You just answered your own question - '\n' is your friend.

What do you mean - print out newline characters in a file?

jim mcnamara,

I mean the ability to see no printing characters ie..... if i run

$ cat -v file.txt

This will print carriage returns.

Is there away to see other non-printing characters?
