Ho fatto qualche funzione per files di configurazioni con stanze... se
a qualcuno possono essere utili:

# Function: get_stanzas
# Purpose : Print the list of stanzas found in $1 file
get_stanzas()
{
   typeset config_file=$1

   awk -F '[][]' '
      NF==3 && $0 ~ /^\[.*\]/ { print $2 }
   ' ${config_file}
}

# Function: set_var_in_stanza
# Purpose : read the stanza from config file and set al parameters as
variable
set_vars_in_stanza()
{
    typeset cfg_file=$1
    typeset cur_stanza=$2

    eval `sed -e 's/[[:space:]]*\=[[:space:]]*/=/g' \
        -e 's/#.*$//' \
        -e 's/[[:space:]]*$//' \
        -e 's/^[[:space:]]*//' \
        -e "s/^\(.*\)=\([^\"']*\)$/\1=\"\2\"/" \
       < $cfg_file \
        | sed -n -e "/^\[$cur_stanza\]/,/^\s*\[/{/^[^;].*\=.*/p;}"`
}

# Function: unset_var_in_stanza
# Purpose : read the stanza from config file and free all parameters
previously set as variables
free_vars_in_stanza()
{
    typeset cfg_file=$1
    typeset cur_stanza=$2

    vars_in_stanzas=$(sed -n
"/^\[$cur_stanza\]/,/^\s*\[/{/^[^#].*\=.*/p;}" < $cfg_file | grep -o
^[^=]*)
    for var in $vars_in_stanzas ; do
        #eval "echo $var=\$$var"
        unset $var
    done
}

Ciao
