Try

Code:

awk -F":" '/Important list/ {print $2}' dailyreports | awk '{print $1}'|while read w
do
   line="${line}${w}"
done

echo ${line}

Or in awk:

Code:

awk '
BEGIN {FS=":"}
{
	if ( $0 ~ /Important list/ )
		c=substr($2,1,1)c
}
END {print c} ' dailyreports

or

Code:

grep "Important list" dailyreports| awk -F":" '{print $2}' | awk '{print $1}'| while read l; do echo -e "$l \c"; done

Which is almost the same Klashxx says in his first example
