Shell Programming and Scripting

That is dependent on number of characters in field, ASCII
is an encoding where each character is represented as
exactly one byte.

It is clear from the sample data you have given there is a
set pattern from alpha characters to digits.

C has isalpha() and isdigit() and most other languages have
something similar to this.

If you use regular expressions [A-Z] or [a-z] and [0-9] will work.

Not given enough information on your sample data, you may
try splitting on whitespace or from alpha char to digit.

Anything wrong with this code you see? I cannot get it to run: I am basically trying to run some awk code within a korn shell. I want to run the trim funciton, but I get complaint when I run the script.


#!/bin/ksh

awk '

function trim(str)
{
sub("^[ ]*", "", str);
sub("[ ]*$", "", str);
return str;
}

gref = substr($0,2,32);
gref = trim(gref);

}'

1. [as always] if on Solaris, use nawk instead of awk.
2. where is you input to awk?
3. what is your ACTION? - you have mis-matched '{}' for your action. I think you want something like this:

Code:

#!/bin/ksh

nawk '
function trim(str)
{
   sub("^[ ]*", "", str);
   sub("[ ]*$", "", str);
   return str;
}

{
  gref = trim(substr($0,2,32));
  print gref
}' path2YourInputFileGoesHere

Thanks vgersh99.

I am using Solaris.

My input to awk is some sort of file. I think I do have the braces messed up. I did get it to work. I am very greatful.
