UNIX Bash: Create incrementally numbered directories
The Problem
You would like to be able to create UNIX directories with numerical names, which increase incrementally, for instance:
0000
0001
0002
0003
etc.
The Solution
Just execute the following bash script in a directory, which contains at least the subdirectory '0000'. The script will create a new directory with a numerical name with trailing zeros precisely being the last created directories name +1.
echo "=== Create new deployment dir ==="
lastdir=$(ls -d [0-9][0-9][0-9][0-9] | tail -1)
myvalue=$lastdir
newvalue="0"
while [ "$newvalue" != "$lastvalue" ]
do
newvalue="$(echo $myvalue | sed 's/^0//')"
lastvalue=$myvalue
myvalue=$newvalue
done
echo "Last created dir: $lastdir"
lastdirnr=$newvalue
newdirnr=$((($lastdirnr) + 1))
newdir=$(printf "%04u" $newdirnr)
echo "Create new dir: $newdir"
mkdir $newdir

(there was one more post I got the 'ls' and 'printf' part from but I cannot find it at the moment :( )
