cannot run multi-line bash command

[w1475963]

when: I paste muti-line bash script into terminal

example:

for ((i=0; i<5; i++)); do
    echo "$i"
done

error:

bash: eval: line 2: syntax error: unexpected end of file from `for' command on line 1

It seems that the issue occurred because a ; was not added when multiple lines of text were merged into one line.

# error(one line)
for ((i=0; i<5; i++)); do echo "$i" done

# success(one line)
for ((i=0; i<5; i++)); do echo "$i" ; done
# It can also run successfully when pasted into fish

btw, if the first line starts with #, it will not be executed either (may be the same reason).

adding a ';' before done, it will run successfully.

for ((i=0; i<5; i++)); do
    echo "$i"
;done

but this ; is unnecessary for bash
