Hi All,

I am trying to check if if column 5 is greater than 90. If greater it will print the term in column 6, else if all are within limit, then it will output "Size is within limit". I can't seem to do that with the below code. The output should only be 1 statement of "Size is within the limit" since all column 5 numbers are less 90. Can somebody advise me what's wrong with my code ?

Input:

/aaa 0 0 0 0 /zzz
/aaa 240553 145567 70931 68 /
/aaa 1170399 800131 311749 72 /qqq
zz 0 0 0 0 /rrr
/xxx 288445 139404 120197 54 /ttt
/xxx 6048174 1946727 4040966 33 /ggg
/xxx 336337 225215 77489 75 /uuu
/xxx 8813861 2025333 6700390 24 /ooo
zzz 496704 35864 460840 8 /ppp
aaa 3073262 1757331 1254466 59 /hhh
aaa 140074829 106235104 32438977 77 /lll
ddd 6048174 1946727 4040966 33 /vvvv
ddd 140074829 106235104 32438977 77 /nnn

BEGIN {}
{
if ($5 > 90) Dir = $6; printf("%5s is over 90%.Pls take note!\n",Dir); 
if ($5 < 90) printf("Size is within Limit.\n");
}
END{}

My Output from the above code:

$ nawk -f awk_proto sys_info2.txt
is over 90%.PPls take note!
Size is within Limit.
is over 90%.PPls take note!
Size is within Limit.
is over 90%.PPls take note!
Size is within Limit.
is over 90%.PPls take note!
Size is within Limit.
is over 90%.PPls take note!
Size is within Limit.

Add the braces

if ($5 > 90) {Dir = $6; printf("%5s is over 90%.Pls take note!\n",Dir); }

Hi anbu,

My output now is below:

$ nawk -f awk_proto sys_info2.txt
Size is within limit.
Size is within limit.
Size is within limit.
Size is within limit.
Size is within limit.
Size is within limit.
Size is within limit.
Size is within limit.
Size is within limit.
Size is within limit.
Size is within limit.
Size is within limit.
Size is within limit.

Can i output only 1 of the above statement when all are within the limits? Once 1 of the value is not within the limits, this statement would not be displayed.

awk '
{
if ($5 > 90) {Dir = $6; printf("%5s is over 90%.Pls take note!\n",Dir); flag=1}
}
END{ if( flag != 1 ) { printf("Size is within Limit.\n"); }' file
