[GRASS-user] simple shell problem

[Jarosław Jasiewicz]

Hi

why:

g.region -g | awk -F"=" '/^nsres=/ {print $2 * 1.45}'

works, but:

bufdist=`g.region -g | awk -F"=" '/^nsres=/ {print $2 * 1.45}'`
or
bufdist=`eval g.region -g | awk -F"=" '/^nsres=/ {print $2 * 1.45}'`

not work, while, wery similar structure:

n=`g.region -g | awk -F"=" '/^n=/ {print $2+2000}'`

works??

i.e what is wrong in bufdist calculation??

thanks if somebody ansfer
