Sometimes it is quite important to have all the time the same length of characters. A small bash script can help and with “printf” the beginning indicated has always the same length.
#!/bin/bash count=0 #counter equals zero # star loop until 9999 is reached while [ $count -le 9999 ] do myvar=$(printf "%.5d" "$count") #define the length in %.5d echo $myvar count=$[$count+1] done exit 0
To get tis into a text file safe this scrip e.g. as counter.sh as executable and pipe it into a file
./counter.sh > couterfile.txt
