Repeat-By: ---- Note ---- Unicode characters: - blank (U+2423) for space (U+20) and - tab (U+2B73) + 7 spaces for Tab (U+9) used for clarity in the following. -------------- heredoc-error.sh: #!/bin/bash sed -f - heredoc-error.sh <<-SCRIPT ␣␣s/something/else/ ⭲ s/more/else/ ␣␣SCRIPT $ . heredoc.sh bash: warning: here-document at line 2 delimited by end-of-file (wanted `SCRIPT') sed: file - line 3: unknown command: `S' $ . heredoc-ok.sh #!/bin/bash sed -f - heredoc-ok.sh <<-SCRIPT ␣␣s/else/else/ ⭲ s/else/else/ ⭲ SCRIPT Fix: I think it'd be convenient if Heredoc supports indentation with spaces at the delimiter line, too. And, BTW, there's a mixture of (leading) backtick (U+60) and (trailing) apostrophe (U+27) at `SCRIPT' and `S' in the error message. Kind regards Gerold 'Geri' Broser
