I need to create folders starting from 00 to 99 (00, 01, 02, 03, etc....) in several hundred places. Is there a single line command that will let me do that?
I know this is old, but my recommendation would be:
for i in
seq -f %02g 0 99 ; do mkdir $i ; done
the -f %02g ensures it stays at least two characters, such as 00 or 99, and will still allow 3 character numbers past 99 so if you have 100 it will not become 001. It will be 00-99 100 instead of 001-100 such as the -w does.
