[non-important] Indent here-docs? - UNIX for Dummies Questions & Answers

I recently coded a typical ftp script looking like

Code:

ftp -n $hostname <<
user $user $pass
<commands..>
quit
!

I know the code fails when you try to indent it like:

Code:

    ftp $hostname <<
    user $user $pass
    <commands..>
    quit
    !

Just for the sake of neat code, is there a way to indent it at all (because I have that in an IF statement)?

In ksh, you can use <<- which will delete leading TABs (but not spaces).
See here-documents.

I see, too bad I like using soft-spaces, instead of hard-tabs for fear it may not display correctly cross-platform.

Thanks.

you could also make the ftp section into each own function and call that function when required ...

Code:

hostname=box
user=user1
pass=passWd1

ftp_files(){
ftp -inv $hostname << !
user $user $pass
<commands..>
quit
!
}

if [ cond ]
then
    ftp_files
else
    <commands...>
fi

Ahh, good idea. Thanks.
