bash - Usage of expect command within a heredoc -

for following tiny expect script function added bash profile:

chai() {     expect <<- eof     spawn ssh myuser@myserver     expect ': $'     send 'mypassword\r'     eof } 

we get:

bash: /etc/profile: line 409: syntax error: unexpected end of file 

what wrong script?

i expect heredoc terminator (eof) @ start of line e.g.

chai() {     expect <<- eof     spawn ssh myuser@myserver     expect ': $'     send 'mypassword\r' eof } 

i see you're using <<- , linked doc:

the - option mark here document limit string (<<-limitstring) suppresses leading tabs (but not spaces) in output. may useful in making script more readable.

so should check script see if have tab preceding commands. eof subject same rules.

cat <<-endofmessage     line 1 of message.     line 2 of message.     line 3 of message.     line 4 of message.     last line of message. endofmessage # output of script flush left. # leading tab in each line not show.
