SHA1 generate with range in terminal -

im trying generate sha1 hashes specified numeric range on terminal

i tried this

for in {1..100};do echo -n i(which ever word) | shasum -a 1 | awk '{print $1}';

doesnt seem working

okay, proper answer instead of comment.

for in {1..100}; echo -n ${i}ball | shasum -a 1 | awk '{print $1}'; done 

mind $ before i in particular.

generally when in doubt echo, use printf instead (-n isn't posix anyway).

generally unexpected outputs pipes these, debug removing progressively more parts of pipe: in case dropping shasum , awk original line show it's printing e.g. "i i i" instead of "1 2 3 4 5".
