Heh - så ku' jeg altså ikke lige ha' at det var så langt det script, så jeg
kom til at nørde lidt mere med det:
#!/bin/sh
InputFile="/home/sites/local/mysql.domains"
BaseDir="/home/sites"
awk 'BEGIN {FS="."}{printf "%s.%s\n", $(NF-1),$NF}' < ${InputFile} | \
while read SecondLevel; do
if [ ! -d ${BaseDir}/${SecondLevel} ] ; then
echo "...Making dir: ${BaseDir}/${SecondLevel}"
mkdir ${BaseDir}/${SecondLevel}
fi
done
...her har jeg så lagt teksthåndteringen over til awk (som jo er bygget til
netop den slags ting) og giver så shell'en lejlighed til at gøre hvad den er
god til :-)
