I want to print entire row of file

awk '{print $0}' inputfile

but sometime before every row have space characters. Example:
" HVLR is not in service on AP 54"

How can i print entire row without space characters ?

thanks

Code:

#delete leading whitespace (spaces, tabs) from front of each line
awk '{sub(/^[ \t]+/, ""); print}'

#delete BOTH leading and trailing whitespace from each line (also removes extra space between fields)
awk '{$1=$1;print}'

If you are not tied to awk. Sed works on removing leading and trailing whitespace.

awk '{print $0 }' inputFile |sed -e 's/^ //g' -e 's/ $//g'
or
sed -e 's/^ //g' -e 's/ $//g' inputFile

sed 's/^[ \t]*//' yourfile name
