Help in error seen in the Bash script - Shell Programming and Scripting

ahjiefreak · #1 01-22-2008

Hi,

I am currently encounter an error of:-
./max.bash: line 45: [: 0.226667: integer expression expected

Basically I try to get the first field of first element in a file. If the first field number does not return me anything from the file, i will set the variable max as 0.

maximum=`cat $version.txt|head -1|awk '{print $1}'`

if [ $maximum -eq 0 ]
then
max=0
else
max=$maximum

It seems that it does not allow max to assigned with floating numbers.

Please help.

Thanks.

Use this logic

Code:

maximum=`cat file1.txt|head -1|awk '{print $1}'`

[ -z $maximum ] && max=0 || max=$maximum
echo $max

//Jadu

max=${maximum:-0}

if maxinum is not blank it will assing 0, otherwise it will assign value of $maxinum
