OS: Fedora 28, Running on a Dell Latitude E7450 Standard RPM Package: bash-4.4.23-1.fc28.x86_64 if you type a multi-line if-then-else-fi statement with a command before the else. Bash does not add a semi-colon before the else when saving to history. Type into command line (watch out for no-break-spaces added by mail)... if true then echo yes # comment - required to activate bug else echo no fi this works fine! outputting "yes" But if you look at the history history|grep i\\f|tail -1 Returning... 830 if true; then echo "yes" else echo "no"; fi You will see the required ';' before the else is missing. Meaning if the command is repeated from history it will go wrong. Producing instead... yes else echo no If the comment was not present, the semicolon is added correctly. Probably effects other muti-line input containing comments too. Anthony Thyssen, writing shell script since 1988
