ciao to all
pay attention to spaces between column name in v.db.renamecol: no
spaces before and after comma.
Command substitution: backticks → $(....) not substantial
differences; the second form is easier to read and write; it is also
nestable (we are all used to ` ` form, but $() is better (IMHO))
This should work (probably):
================================
db.columns test
key_column="cat"
suffix="_tmp"
for column in `db.columns test`; do
if [ "$column" != "$key_column" ]; then
tempcolumn=$(echo $column | awk '{print tolower($1)}')
tempcolumn=$tempcolumn$suffix
v.db.renamecol map=test layer=1 column=$column,$tempcolumn
lower_column=$(echo $tempcolumn $suffix| awk '{print
substr($1,1,length($1)-length($2))}')
v.db.renamecol map=test layer=1 column=$tempcolumn,$lower_column
fi
done
db.columns test
===================
ciao
