78. true, false
true and
false are useful to make multi-line comments in a bash script:
# multi-line comment
if false; then
echo hello
echo hello
echo hello
fi
To comment these
echo statements back in:
if true; then
echo hello
echo hello
echo hello
fi
The formal man page definitions of these commands are amusing:
true:
"do nothing, successfully (exit with a status code indicating success)";
false:
"do nothing, unsuccessfully (exit with a status code indicating failure)".
