SC1135 – ShellCheck Wiki

See this page on GitHub


Prefer escape over ending quote to make $ literal. Instead of "It costs $"5, use "It costs \$5"

Problematic code:

echo "The apples are $""1 each"
eval "var=$"name

Correct code:

echo "The apples are \$1 each"
eval "var=\$name"
# or better yet: var="${!name}"


The script appears to be closing a double quoted string for the sole purpose of making a dollar sign $ literal.

While this happens to work, the better solution is instead to escape it with a backslash. This allows the double quoted string to continue uninterrupted, thereby reducing the visual noise of stopping and starting quotes in the middle of a shell word.
