Awk Problem - Fixing needed
os: sunos/linux
shell: bash

Code:
                        awk -v PCT="$PERCENTAGE" -v UWARN="$UWARNING" -v UCRIT="$UCRITICAL" 'BEGIN {
                                PCT=PCT+0; UWARN=UWARN+0; UCRIT=UCRIT+0 ;
                                if(PCT<UWARN) { printf \" '${FILESYS}': size('${SIZE}'),usage('${USAGE}'),pct('$PERCENTAGE')\" } }'

i'm getting errors like:

Code:
awk: cmd. line:2:                         	if(PCT<UWARN) { printf \" Virtual
awk: cmd. line:2:                         	                       ^ backslash not last character on line
awk: cmd. line:2:                         	if(PCT<UWARN) { printf \" Memory
awk: cmd. line:2:                         	                       ^ backslash not last character on line

yes i already tried without the back slash and without the "printf". i tried "print". but still not working.

That is a thick mix of awk and shell. I can't even tell what you're trying to do. It almost looks like you're trying to get it to print shell statements, but that's seldom a good idea -- why not do that in the shell itself?

Please tell us what exactly you're trying to do, not just post inscrutable code which can't.

Code:
if(PCT<UWARN)

i would have used shell but shell does not handle mathematical equations that involve decimals or negative numbers...which is why i'm using awk.

this seems like an easy fix because all i want to do is just print variables. but this is driving me crazy.

the value inside $FILESYS is usually one word (without any spaces) but some times it can be two words. i.e. "Physical Memory" or "Virtual Memory" or "/var" or "/boot".

It still isn't clear what you're trying to do. You're importing $PERCENTAGE, $UWARNING, and $UCRITICAL; but you're not importing $FILESYS or $USAGE and you're not showing that they are being set in your awk script???

Making lots of wild guesses, would the following be close to what you're trying to do?
Code:
awk -v PCT="$PERCENTAGE" -v UWARN="$UWARNING" -v UCRIT="$UCRITICAL" \
    -v FILESYS="$FILESYS" -v USAGE="$USAGE" \
'BEGIN {PCT=PCT+0;
            UWARN=UWARN+0;
            UCRIT=UCRIT+0;
            if(PCT<UWARN) {
                printf "%s: size(%s),usage(%s),pct(%f)",FILESYS,SIZE,USAGE,PCT}
        }
