File Processing: Handling spaces in a line
Hi All,

Iam trying to get a file processed and some lines have spaces...the below is not working

Want to remove empty line
Want to remove lines that start with #
Avoid line with substring WHOA
When trying to get the substring from the var also Iam having trouble

file is like VAR=VALUE, an fiel to set environment to be exact


HTML Code:
for var in $(cat -r $file | sed '/^$/d' | grep -v -E ""^\#"" )
do
      subvar=`echo $var | cut -c1-4`
      if [ "$subvar" != "WHOA" ]
      then
                eval export $var
      fi
done
Sample Input

Code:
MONITOR_OFF=YES
DIR=/usr/as/brs
DATADIR=/usr/df/brs
SHELLDIR1=/usr/as/brs
SHELLDIR2=/usr/as/brs
WHOA= %s : %S - %C [%c xxxx]    --- This is the line Iam trying to avoid by substring logic, this has spaces in between, need logic to get only WHOA also from this line

I dont know how to pass the file using while and IFS as Iam doing some stuff before I use it


Regards
