Hi,
How can I export variables from awk? For example, I have this script: cat awkscr #start of scr bdf | awk '(/ *% /) && (length($NF)>maxl) {maxl=length($NF)} END {print maxl; export maxl}' echo $maxl #end of scr The echo return nothing. I know I can do it in this way: maxl=`bdf | awk '(/ *% /) && (length($NF)>maxl) {maxl=length($NF)} END {print maxl}'` but if I have 2 or more variables need to pass back to the shell, this doesn't work. Any idea???
