One line if statement in bash -

i've never programed in bash... yet i'm trying solve problem anchievement in game (codingame.com)

i have following code:

for (( i=0; i<n-1; i++ ));    tmp=$(( sorted_array[i+1] - sorted_array[i] ));    if [ $tmp < $result ]; result=$tmp fi done

and error:

/tmp/answer.sh: line 42: syntax error near unexpected token `done'at answer.sh. on line 42 /tmp/answer.sh: line 42: `done' @ answer.sh. on line 42

i want compare adjacent values of array , store minimun diference between them... cant figure how if statement in bash

each command must terminated, either newline or semi-colon. in case, need separate assignment of result keyword fi. try adding semi-colon;

for (( i=0; i<n-1; i++ ));    tmp=$(( sorted_array[i+1] - sorted_array[i] ))    if [ $tmp -lt $result ]; result=$tmp; fi done

also, need use lt rather <, since < redirection operator. (unless intend run command named $tmp input file named variable $result)
