UNIX Bash: Create incrementally numbered directories
You would like to be able to create UNIX directories with numerical names, which increase incrementally, for instance:
0000 0001 0002 0003 etc.
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 :( )
