Creating a directory with a date-based name

Creating a directory with a date-based name

[zzapper]

Hi Ya,

I'm a zsh newbie.

I have the following bash script, which will create a directory say
06Dec03 if this directoryy exists then create 06Dec03v2

I need to enhance it to create 06Dec03v3,4,5,6 etc. should these
directories exist.

How would this best be done in zsh?

dirbackup="c:/backup/mysqlnext/"
cd $dirbackup
eval dat=$(date.exe '+%d%b%y')

if ! mkdir $dat
then
   dat=$dat"v2"
   if mkdir $dat
   then
   echo "created $dat"
   fi
fi
cd $dat
zzapper (vim & zsh)
--

vim -c ":%s/^/WhfgTNabgureRIvzSUnpxre/|:%s/[R-T]/ /Ig|:normal ggVGg?"

integer vers=2

while [[ -d ${dat}v$vers ]]; do
   (( ++vers ))
done
mkdir ${dat}v$vers


(actually the same in bash, as far as I can see.)

Like this (untested):

  dirbackup="c:/backup/mysqlnext/"
  cd "$dirbackup"
  eval dat=$(date.exe '+%d%b%y')

  if ! mkdir "$dat"; then
     i=1
     finished=""
     while [ -z "$finished" ] && [ "$i" != 9999 ]; do
       i=$[i+1]
       dat="${dat}v$i"
       if mkdir "$dat"; then
           echo "created $dat"
       fi
     done
  fi
  cd $dat

Ciao
